Robot elephant trunk learns motor skills like a baby
March 15, 2014
Designed to bring the dexterity of an elephant’s trunk to industrial robots, the appendage I am wrestling was launched by German engineering firm Festo as a proof-of-concept in 2010. The design showed that a trunk formed of 3D-printed segments can be controlled by an array of pneumatic artificial muscles.
But beyond a handful of motions, such as shaking hands – including once with German chancellor Angela Merkel, the machine wasn’t built with its own precision control software. “They deliver it without much control. You can try, but the arm will be centimetres from where it should be, which is no good” says Steil, an intelligent systems engineer at Bielefeld University, also in Germany.
