abstract = "Grasping a target object among clutter objects without collision requires machine intelligence. Machine intelligence includes environment 
recognition, target & obstacle recognition, collision-free path planning, and object grasping intelligence of robot hands. In this work, 
we implement such system in simulation and hardware to grasp a target object without collision. We use a RGB-D image sensor to recognize 
the environment and objects. Various path-finding algorithms been implemented and tested to find collision-free paths. Finally for an 
anthropomorphic robot hand, object grasping intelligence is learned through deep reinforcement learning. In our simulation environment, 
grasping a target out of five clutter objects, showed an average success rate of 78.8%and a collision rate of 34% without path planning. 
Whereas our system combined with path planning showed an average success rate of 94% and an average collision rate of 20%. In our 
hardware environment grasping a target out of three clutter objects showed an average success rate of 30% and a collision rate of 97% 
without path planning whereas our system combined with path planning showed an average success rate of 90% and an average collision 
rate of 23%. Our results show that grasping a target object in clutter is feasible with vision intelligence, path planning, and deep RL."
