System description
The DLR HIT Hand II from HIT (Harbin Institute of technology) and DLR Institut for Robotics and Mechatronic is further stage of the DLR HIT Hand I. In contrast to the DLR HIT Hand I the new DLR HIT Hand II has five modular fingers with four joint and three active degrees of freedoms and is still lighter and smaller. As the DLR Hit Hand I in the year 2007 the DLR Hit Hand II was awarded with the IF-Design-Award 2009. The Hand is used on Space Justin setup for grasping objects with shared autonomy. The shared autonomy supports the human tele manipulator during for example space operations with autonomous grasp planning. Main topic on the hardware research is to use the Hit Hand II Fingers for Reconfigurable Dexterous ReDex series endeffectors and to build Human machine interface (HMI) based on modular fingers.
