    Successful Cybathlon Experience 2018

    On  June 23rd, HSR Enhanced participated in the CYBATHLON Experience 2018 as part of the Rollivision fair at Swiss Paraplegic Centre Nottwil. In four demo runs, our pilot Florian Hauser had the chance to test two brand new obstacles from the CYBATHLON 2020 race rules: ‘Cobblestones’ and ‘Ramp&Door’. For Florian, it was only his second training with his new race wheelchair “ZED Evolution”. We are very proud that he solved all the obstacles presented to him flawlessly, and that he continuously improved the performance in every single run! Read more...

    New stairclimbing module

    Kevin Bürgi, student of Mechanical Engineering, has developed a new stairclimbing module for the race chair in his Bachelor Thesis. It enables our pilot to overcome stairs with more than three steps up and down. This has become necessary due to the new CYBATHLON race rules, which require the pilots to climb up and down stairs with six steps. Kevin decided not to improve the former module, but to develop a completely new one. He suggests a crawler system, which is more suitable for stairs with arbitrary number of steps, and it is more comfortable for the pilot. As soon as Kevin has received all the parts for his new module, he will finish the assembly and complete his thesis. The final implementation of the crawler system will follow in the next weeks and will see rigid testing and improvements by feedbacks from our pilot Florian Hauser.

    A robotic system to remotely open the door

    Philipp Weber, student of Mechanical Engineering, is currently finalizing his Bachelor Thesis. He has evaluated and defined a robotic system to remotely open the door at the Ramp&Door obstacle. His concept is based on the commercially available Kinova Robotic Arm. Philipp has integrated it into the existing wheelchair, paying special attention to the safety of the pilot, who is commanding the robotic arm while sitting directly in its work envelope. Moreover, all the wheelchair’s existing functions, e.g. longitudinal seat adjustment, had to be maintained. Philipp’s solution is to use a commercially available collaborative robot by Kinova Robotics, integrate it into the race chair’s moveable seat and equip it with a customized passive end-effector, which allows to press door bell buttons and to open latched doors. The results have already been tested by our pilot Florian Hauser and will be shown to the public at CYBATHLON Experience in Nottwil on June 23rd, 2018 (Event link: https://goo.gl/oPbN6F).

    Students improve chassis

    Samuel Stähli and Thierry Zimmerman, students of mechanical engineering, improved the chassis and the steering drive of the Cybathlon wheelchair in a student project. They aimed at a functional sample with a better stability and maneuverability. By adapting the suspensions, the students optimized the lateral stability of the chassis. They improved the maneuverability by replacing the former linear drive by a separate drive in each wheel. This resulted in a seven times faster steering speed. Thank you, Samuel and Thierry, for your precious contribution to the team HSR Enhanced!
