Robotic arm!! designed to catch flying objects
London, May 12 (IANS) With its palm open, this robot is completely motionless. A split second later, it suddenly unwinds and catches all sorts of flying objects thrown in its direction - a tennis racket, a ball, a bottle and so on. Researchers at the Swiss Federal Institute of Technology in Lausanne have developed a bionic arm that capable of reacting on the spot and grasping objects with complex shapes and trajectories in less than five-hundredths of a second! This arm measures about 1.5 metres long and keeps an upright position. It has three joints and a sophisticated hand with four fingers. "Increasingly present in our daily lives and used to perform various tasks, robots will be able to either catch or dodge complex objects in full-motion," said Aude Billard, head of Learning Algorithms and Systems Laboratory (LASA) at EPFL. Not only do we need machines able to react on the spot, but also to predict the moving object's dynamics and generate a...
