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
