to perform a multitude of tasks 2. Controlling : challenging due to high dimensionality and large number of potential contacts. 3. Success of DRL in robotics has thus far been limited to simpler manipulators and tasks 4VNNBSZ 1. Model-free DRL can effectively scale up to complex manipulation tasks ( in simulated experiments ) 2. use of a small number of human demonstrations -> sample complexity can be significantly reduced 3. Use of demonstrations -> natural movements 4. successful policies -> object relocation, in-hand manipulation, tool use, door opening
