Elastic Robot Links: Curse or Blessing?

TUDOR robot

It is a demanding challenge to avoid unwanted structural elasticity during the design of lightweight robot mechanisms. 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

How infants tell us how to control the Bionic Handling Assistant

Few days old newborn already try to reach

Festo’s Bionic Handling Assistant (BHA) was revealed to the public in 2010 and got quite some media coverage. 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

Torus model to simulate BHA`s kinematic structure

In April 2010 the Bionic Handling Assistant (BHA) from Festo was revealed to public at the Hannover Fair 2010 [1] and won several prices like the German Future Award 2010 [2] . 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
