Instead, it comes with a rich pool of open source software, a PC board and an EtherCAT interface to connect to the drive electronics. This gives researchers and students a lot of leeway for the development of new algorithms for robot control.” EC 45 flat motors drive the youBot Ø 22 mm, brushless, 100 W, with Hall sensors Get The Big Picture! Highly focused: Nirmal Giftsun (left) and Alexander Moriarty of Hochschule Bonn-Rhein-Sieg are participating in the Robocup 2013, a robotics compe- tition attended by 2000 researchers and students from all over the world. They are hoping for a win in the discipline “Robocup@work”. Their youBot has to find certain objects in an obstacle course and bring them to the proper place - fully autonomously, using only sensors and algorithms. The joints of the youBot contain flat motors by maxon motor. They are responsible for the precise and powerful movements of the robotic arm.
