KEMARO Autonome Roboter für den sauberen Industriealltag Thu, 19 Jan 2023 10:17:36 +0000 en-US hourly 1 KEMARO 32 32 At the Forefront of Robotics Wed, 18 Jan 2023 09:25:35 +0000 After graduating from business school with a focus on languages, Silvan Spescha from Engelburg (SG) embarked on two language stays. In French-speaking Switzerland and Canada, he honed his skills in English and French, and familiarized himself with new cultures. To gain early work experience prior to his studies, Silvan completed an internship with the City of St.Gallen in the Human Resources Office. During this time, he realized that a career in public service was not for him – he wanted to explore the vast world. He enrolled in the Bachelor’s degree program in “International Management” with a specialization in strategic management. Before that, he fulfilled his military service as a tank reconnaissance officer. Silvan Spescha completed his Bachelor’s degree with determination, as he was already aware at the time that he needed to attain good grades for a potential Master’s continuation. A few months before graduation, the Corona pandemic threw a curveball. Silvan Spescha completed his Bachelor’s degree with determination, as he was already aware at the time that he needed to attain good grades for a potential Master’s continuation. Half a year later than originally planned (and with the six-month experience abroad) Silvan Spescha completed his Bachelor’s degree – with a specialization in International Strategic Management and a second specialization in Accounting and Controlling.

Connection thanks to a Practical Project

The now 24-year-old then moved to Zurich to work for a consulting firm – not at all his desired field, as he soon realized. And so, after a conversation with KEMARO co-founder Martin Gadient, whom he had met during a previous practical project, he began an internship at the Eschlikon-based robotics company. “The fact that I delayed my semester abroad and didn’t immediately pursue my Master’s degree was fortuitous in retrospect – because I would not have had the opportunity at KEMARO AG.” At the beginning, the start-up environment was a bit of a culture shock: “In the consulting environment I encountered designer chairs and glass walls, but at KEMARO AG we held our meetings on wooden benches at the time.” A minor detail – because the team, the numerous freedoms and the innovative product continue to convince him today. “Thanks to the many freedoms, I am able to achieve and truly develop the business.” He evaluated new tools early on and contacted potential investors. His open, interested manner won them over and he eventually secured a permanent position with the Swiss robotics specialists.

Potential for the Future

Parallel to his work, Silvan Spescha is pursuing a Master’s degree in Business Innovation at the HSG. Silvan no longer likes to hear the stereotypes associated with HSG students. “I don’t do a job for prestige, but to make a difference and gain practical experience.” Thanks to his job at KEMARO AG, he is close to the business world, with both feet on the ground. He aspires to actively influence and shape the robotics company. To this end, he has acquired knowledge about the industry, social transformation, and various business models of robotics companies. “I have great plans for KEMARO AG.”

Successful Series A funding round: Accelerating the global expansion Thu, 15 Dec 2022 07:40:09 +0000 KEMARO AG’s K900 is a globally unique autonomous cleaning robot for industrial use, developed with Swiss engineering methods. The company employs over twenty people at its site in Eschlikon TG. KEMARO AG secured additional capital in a Series A funding round to continue its worldwide expansion.

KEMARO AG’s latest funding round of close to CHF 5million was carried out with five investors, of which three were existing shareholders reinvesting. Spicehaus Partners acted as lead investor. “The past two years have clearly shown that KEMARO AG is successfully catering to an increasing demand for autonomous and digital solutions in industrial areas, not only for cleaning purposes but also from a health and safety perspective,” said Daniel Andres, a Founding Partner at Spicehaus Partners AG. One of the new investors, W+P Beteiligungen AG from Wil SG, also found the breakthrough very promising. “The K900 can be used sensibly in almost all of the logistics and production buildings that our company creates,” says owner Maurice Weber about the commitment.

The largest investor from Japan

In addition to W+P, a strategic partnership has been secured with another corporate investor, the Obayashi Corporation. The company is one of Japan’s largest construction companies, listed on the Nikkei 225. Obayashi Corporation also participates in KEMARO AG’s funding round. Tamaki Horii, Head of the Corporate Strategy and Business Development Division at Obayashi Corporation, anticipates great worldwide market potential for the unique dry-cleaning robot: “We are looking forward to supporting and accompanying KEMARO AG in this phase.” The K900 is already in use in 20 countries today, and the additional capital will be used to attain more of the Asian and the American markets. “This Series A financing round enables us to continue our global expansion plans,” says Armin Koller, co-founder and chairman of the board at KEMARO AG. “With the investors, we not only gained necessary capital, but also brought on board a lot of entrepreneurial experience and strategic market expansion.”

Winner of the Swiss Logistics Award

A significant milestone for KEMARO AG was its victory this summer at the Swiss Logistics Awards, where it triumphed over competition from well-known Swiss companies including SBB-Cargo, Feldschlösschen and Denner. The jury was particularly impressed by the ecological sustainability, health benefits and cost savings that come with using a K900. Added to that is the fact that the sweeping robot is produced in Switzerland. The Swiss Logistics Award gave the company a lot of recognition and momentum for further work.

About the K900: Fully autonomous mobile robotics (AMR) made in Eschlikon

The K900 dry-cleaning robot cleans autonomously and smartly, perceiving its surroundings using distance measurement algorithms that rely on optical sensors and supporting 3-D sensors. KEMARO’s robotics technology, developed in-house and based on the latest technological advances, enables full autonomous operation around the clock. It cleans floors without chemicals or water, and autonomously disposes of packaging residues, industrial dust and pallet splinters. With its two large front brushes, the robot cleans right up against objects and walls. Precise live mapping of the room and sophisticated navigation algorithms also enable unprecedented cleaning performance and quality.

“Creating both real and digital life experiences is my goal.” Tue, 06 Dec 2022 08:53:19 +0000 Having travelled halfway around the world, Matthew Bertschinger arrived in Eschlikon at KEMARO AG a few months ago. The 23-year-old has decided to start a new chapter in Switzerland after 18 years in New Zealand. As a child, he immigrated with his family to his mother’s home country, occasionally returning to Switzerland during the holidays, and is now back and living here.

Matthew has been interested in technology and robotics from a young age and went on to study mechatronic Engineering in Christchurch. This is an engineering discipline that deals with mechanical and electronic systems and how they interact. During one of his summer holidays, he travelled to Switzerland and did an internship at a smart sensor development company near Lake Zurich. In his spare time, he taught himself web development, using video tutorials and online courses. This is how the self-proclaimed nerd became a versatile all-rounder in software and hardware. With this knowledge, he founded his first start-up at the age of 22, an organisation and networking platform for administration in sports clubs.

The somewhat different nerd

Matthew does not embody the classic image of a nerd who only sits in front of a computer. In his free time, he tries to travel and play sport as often as possible. In addition to hiking, skiing and football, he plays floorball at the highest level in New Zealand. His father was one of the pioneers who brought floorball from Switzerland to New Zealand and promoted its popularity in the island nation.

One factor in Matthew’s move to Switzerland was the opportunity to advance in floorball, which was becoming difficult in New Zealand. He currently trains twice a week with Unihockey Luzern. For him, the almost two-hour drive to Central Switzerland is “no big deal”, as he is used to travelling much longer distances in New Zealand. He benefits from the flexible working hours at KEMARO AG and enjoys working on the train on his way to training.

Future prospects

At KEMARO AG, Matthew works as a web developer, utlilising the skills he learnt through his degree in mechatronics and experience in the startup environment. He enjoys developing web-based technologies to connect people and make jobs easier and faster. He especially appreciates being able to see the results of his work directly and test them on the robot. He also enjoys learning from his friendly, competent colleagues.

He sees many advantages for people in automation and the further development of robots. Whether in the world of industry, healthcare or agriculture – there are still physical tasks in many areas that can be performed by machines, giving people more time and reducing their risk of physical injury. He sees future jobs primarily in the creative and social sectors. For his own future, Matthew wants an independent life as a digital nomad. “Simultaneously creating real and digital life experiences is my goal.”

K900: Lord of Ventilation Tue, 06 Sep 2022 09:59:02 +0000
Air filter and airflow

The K900’s housing is pressurized by a powerful and compact fan. In the front area of the robot, at the dirt opening, an airflow is created by the negative pressure. This is the area where most of the dust is created, which is sucked into the robot by the air flow and passed through the air filter, almost 2 m2 in size. The size of the air filter corresponds to that of a ride-on sweeper. The filtered air is directed out of the robot through the sensors so that they are protected and freed from accumulating dust by the permanent air flow – the patented process ensures clear vision. Intensive tests have confirmed that the maintenance interval of the sensors is extended by a factor of 20 thanks to the air flow.

Performance and use

The K900 can filter up to 2.6 m³ of air per minute, which corresponds to 156 m³ per hour. This is 1,250,000 litres of air cleaned at eight hours of operation per day. Assuming that the robot operates eight hours per day, it is equivalent to the amount of air that 85 people breathe in and out per day. Constantly cleaning a room significantly lowers the concentration of dust particles in the air. Less dust settles on work surfaces, goods and machines, not to mention in the lungs of the employees. If wet cleaning had once been necessary to absorb the dust with the water, the K900’s dust binding usually eliminates the need for this. This saves water and chemicals, and no additional moisture enters the room.

The filter of the K900 is class «M» and is particularly suitable for cleaning industrial dirt. This also includes metal and wood dust particles, as well as normal house dust. To benefit permanently from the air filter, the filter must be serviced once a week, depending on the degree of contamination. The best way to do this is with a hoover, so the dust does not get back into the room. KEMARO offers a wall-mounted hoover for easy maintenance, with a mounting directly above the charging station of the K900. If the filter becomes unclean, the customer can replace it himself.

Care should be taken if the filter seal or filter membrane are damaged. If this occurs then filters, instead of ventilatingthe sensors with clean air, will send the dust tothe sensors, which can lead to malfunctions. Therefore, we recommend checking the air filter regularly.

KEMARO AG wins Swiss Logistics Award 2022 Mon, 04 Jul 2022 08:51:07 +0000

KEMARO’s K900 smart vacuum sweeper robot won the 2022 Swiss Logistics Award.

Bern, 9th of June, 2022 – The Swiss company KEMARO AG has launched the first autonomous dry cleaning robot for industrial use. The Eschlikon-based company’s autonomous solution is revolutionizing the cleaning market for both industrial and commercial areas. KEMARO AG received the Swiss Logistics Award on the 8th of June, 2022 for its Swiss engineering skills.

Whether warehouses, large workshops, or industrial plants: the world’s first dry cleaning robot (the K900 from KEMARO AG) cleans autonomously and intelligently, navigating its environment using 3D sensors, and SLAM algorithms. The K900 won the prestigious Swiss Logistics award due to its environmental sustainability, operational safety, and cost savings, while also being packed full of Swiss engineering and manufactured in Switzerland.

Eco-friendly and low-maintenance
The fully autonomous K900 cleans industrial floors sustainably, without chemicals or water. The is remarkable – not only because of the reduced maintenance, but also from an environmental point of view. The K900 autonomously clears floors of things like packaging debris, industrial dust, and pallet splinters, and with its two large sweeper brushes it can clean right up against objects and walls. As the catch container has a 35 liter storage capacity it is ideally sized for industrial use. The rechargeable battery also provides a cleaning time of up to five hours.

Reducing dust pollution
Managing the fine dust often found in industrial and logistical operations is a serious challenge for employees, production facilities and products. The cleaning robot is the solution: The K900 has a built-in dust extraction system thus preventing dust build up. The built-in dust class M filter removes wood and metal dust, along with paint particles, from approximately 3.5 cubic meters of air per minute.
A low dust concentration minimizes the wear on machine parts in the intralogistical systems, and ensures dust does not settle on stored packages or other production goods.

Halving cleaning costs
The labor costs for cleaning halls can also be greatly minimized by using the dry cleaning robot, and this working time can then be invested into value-adding activities. The K900 can reduce cleaning costs by up to 50 percent. This means that the purchase price is practically amortized within a year. Furthermore, the vacuum sweeper robot provides a potential alternative for companies where cleaning can otherwise only be done when adhering to high safety requirements.

Swiss innovation
The K900 is equipped with state-of-the-art technology. The active light detection and distance measurement (Lidar) sensor scans the robot’s surroundings 40 times per second. The K900 creates a map based on the reflected light within the surrounding 20 meters and autonomously calculates its optimal drive-path. The Lidar is supported by a 3D sensor that conveys the reflectivity and relative distance of surrounding objects to the robot. The measured values from both sensors are used together by the K900’s computing unit to ensure precision, reliability, and optimal navigation.

The Swiss Logistics Award goes to a company for special market and customer-orientated process solutions that have demonstrated an above-average market success. “The K900 industrial vacuum sweeper is full of Swiss engineering know-how and is a showcase project in the age of Industry 4.0,” – said by Renate Gröger Frehner, head judge of the Swiss Logistics Award, Director of Real Estate and Operations at the University Hospital Zurich, when explaining the decision. The winner and the nominees can participate in the competition for the European Award for Logistics Excellence (ELA). Information about the other three nominated projects can be found at . Photos from the award ceremony can be downloaded from 2pm on the 9th of June, 2022.

K900 and 3D sensor E Wed, 01 Jun 2022 08:00:56 +0000

The way our 3D sensor works is significantly different from conventional cameras. It centers on conveying spatial impressions to the user. The sensor collects information on the shape and position of all light-reflecting surfaces in the environment, and enables the K900 to detect obstacles.

How a 3D sensor works

A 3D sensor measures the distance between the device and the nearest surface, point by point, using the time-of-flight (ToF) principle. This method uses the known speed of light in a medium, e.g. air, to measure the distance to the surface point of the object in question. To do so, the 3D sensor uses infrared light, which is invisible to the human eye. Reflective behavior is the decisive factor here. Time-of-flight is suitable for one-dimensional distance measurement as well as for obtaining 3D contours. The sensor illuminates the site with either an integrated or external light source and calculates the relative distance based on the light reflected from the surface. If the device projects light itself, this is referred to as an active ToF system. A passive system is one in which the sensor relies on an external light source. The 3D sensor produces a grayscale image that indicates how far away an object is; the lighter the gray value, the farther away the object.

The colors show the infrared light emitted. The top image visualizes the reflection of the objects, the one below their depth.

The K900’s 3D sensor

The K900 features an active 3D sensor. Infrared light is emitted from the device to measure the distance to the nearest object in the room based on travel time and surface characteristics. The active sensor can also be used in the dark, which means that the K900 robot can also be used to clean at night.

The range of the sensor is approx. five meters. Within this distance, the light being emitted decreases in strength. Objects that are further away are not detected. The sensor supports the LiDAR, which is mounted at a height of 33 cm. The LiDAR serves as an orientation and obstacle detection system. The sensor additionally detects anything below these 33 cm and keeps the robot from driving into low objects. There is a significant cost difference in using a combined LiDAR and 3D sensor system instead of one that relies on LiDAR technology alone. However, such a combination offers massive improvements in orientation and cleaning results.

Who is Software developer Dominic Streiff? Tue, 31 May 2022 07:51:28 +0000

“I wish that robots would not make the world even faster, but give us back some time to live.”

After studying electrical engineering at ETH, Dominic Streiff wanted to work in applied robotics. During his final project in the bachelor’s program, he focused on the locomotor system of a humanoid robot. While completing his master’s, his fascination with a robots’ perceptual abilities and its“sense of direction” crystallized. It was important to him to work on up-and-comingprojects with design potential. He soon had enough of academicprojects and began specifically looked for a company with a marketable robotic product, and thus found KEMARO AG. With the K900, he found a product that was ready for the market, but not yet fully developed. Today, he particularly appreciates the direct feedback from customers about his work as a software engineer, and that he is able to quickly act on this. He feels well integrated in the small team and is surrounded by knowledgeable colleagues.

“There are still many labor intensive jobs that are time-consuming, expensive and boring,” mentions Dominic Streiff. Not only does he need to have fun at work, but there has to be a reason for doing it, a vision. “We need to changethe system to improve life for people”. For him, the worst thing is to fill time with boring, exhausting work. He sees the introduction ofjob automation, using robots and artificial intelligence (AI), as something that needs to happen in numerous industries, for example, to standardize the 4-day week or significantly reduce stress for workers. “Humans should devote themselves to more creative activities again, where they are superior to robots,” he said. “I wish that robots would not make the world even faster, but give us back some time to live.”

He has bigger things in mind for KEMARO AG. Cleaning, he believes, is just the beginning. A broad portfolio with robots for a wide variety of applications is to be developed and marketed. In his opinion, it would be ideal if all robots were available on a common platform. This would make it possible to adapt robots on a modular basis and fulfill customer-specific wishes.

Of course, he also sees problems, for example the wear and tear on rare resources needed to produce robots and computer systems. The high computing power of powerful AIs also requires an enormous amount of energy. In his opinion, this must be factored in when weighing up the benefits. When asked about the loss of jobs, Dominic Streiff answered without hesitation: “We are not taking away jobs, we are creating new ones. The more robots there are in the world, the more manufacturing and maintenance jobs there will be.” Additionally, more time would be available for value-added work. It’s understandable that not everyone has the training and intellect for complex tasks, he said, but almost everything can be simplified. “Ultimately, you can do any complex task in ten less complex tasks.” This makes sense and offers a new, promising perspective.

Above the clouds, the memory must be limitless Mon, 25 Apr 2022 11:31:33 +0000

A cloud is a group of IT services in the form of data storage, applications and servers, such as Microsoft Outlook, which are connected to each other in a network. Users can store their data on these, and have on-demand access to that data anytime and anywhere, irrespective of the device they are accessing it on; all that is required is an Internet connection. Additional storage space can easily be purchased without needing to change the access device. These cloud resources are usually accessed by the user via a website or app. Thus, all data can be stored centrally in one place.

The K900 and the cloud

Individual settings allow the K900 to automatically connect and directly communicate with the cloud when it is switched on. The robot sends status messages to the cloud at regular intervals, and stores the data there. This connection makes it possible for the user to manage the robot remotely and to view the cleaning logs, also known as missions. Users who have multiple robots can therefore manage the data of their entire fleet from one location.
Of course, the K900 also works without the cloud. However, one must then be within physical reach of the robot to access it. Those who do not want to connect the robot into the cloud network can connect to it either via a hotspot or a WLAN network at their location.

Security factors

To ensure the security of data transmission, communication between the K900 robot and the Cloud is secured via HTTPS. The abbreviation HTTPS stands for “Hypertext Transfer Protocol Secure”, which translates to “Secure Hypertext Transfer Protocol”. This protocol performs two functions:

  • The communication and connection between the web client and the web server are encrypted. This is to prevent unauthorized third parties from reading the communication.
  • The web server is authenticated by sending a certificate to the web client at the very beginning of the communication, which certifies the trustworthiness of the domain.

There are no perfect systems, however, with HTTPS, the security level on the device and the cloud is roughly comparable. In addition, a so-called “token”, a kind of secret, is stored on the robot, which is validated on the cloud side so that not just any person can send data to the cloud. This helps the robot to verify itself. Most security vulnerabilities still arise from human error.
