On January 4, 2022, leading polymer company Covestro announced a partnership with Bear Robotics, manufacturer of the Servi™ line of hotel robots
.
When designing Servi™, Bear Robotics needed a material that was aesthetically pleasing, dimensionally stable, impact-resistant and chemical-resistant
.
After extensive testing, they found that the PC/PET combination of Makroblend® UltraTough met the requirements
.
Servi™ is well-timed in the market as restaurateurs face labor shortages and worker well-being is high
.
Complementing the modern kitchen and its service staff, Servi™ and Servi™ Mini enable service staff to focus more deeply on customer experience and satisfaction, while improving Overall efficiency, thereby reducing stress on restaurant staff
.
As a fully self-driving robot, Servi™ includes an array of cameras, sensors and processors, as well as an advanced lidar system, allowing it to not only reach the correct destination, but also to navigate customers and other unpredictable ahead of time Navigation in hall and back hall situations
.
Bear Robotics needed a material that could withstand shock and the chemistry of repeated cleaning, while keeping the sensitive electronics inside safe
.
Makroblend® UT was selected for these properties, along with its excellent plasticity and good paintability
.
Covestro, with more than 50 years of polycarbonate manufacturing experience, played a key role in finding the right material for this new innovative device
.
In general, this molded plastic has a lower carbon dioxide equivalent (CO2e) compared to custom fabrication using metal or other commonly used materials
.
Dan Elliott, senior mechanical engineer at Bear Robotics, said: “Covestro’s broad selection of specialty polymers, technical support and expertise made them the right choice when it came to choosing a company to supply materials for some of our major plastic components
.
”
In addition, Makroblend® UT has a moderate viscosity, making it an easier material to process than the injection molder expected
.
