However, the feasibility of fast and precise end effector positioning for an elastic link arm has been exemplified with ball catching experiments[1] Malzahn, Jörn, Anh Son Phung, and Torsten Bertram. “A Multi-Link-Flexible Robot Arm Catching Thrown Balls.” 7th ...

Link elasticity aggravates the precise position control of the robot due to configuration dependent static deflections and prolong settling times because of long lasting oscillations. Apart from robotics we find similar design criteria in e. g. in fire-rescue ... Read more

Its bionic features make it especially cool, yet at the same time they make control especially hard as we already covered in our last article: Simulation of the Bionic Handling Assistant. The structure and functioning of the Bionic Handling Assistant ... Read more

In February 2011 we got our own BHA and were pretty excited because we knew at that time no-one could do with it what we wanted to do with it: controlling ... Read more
