Efficient Grasp Planning
Coarse to Fine Strategy Approach table reference frame Adjust height and distance to table Align itself to workspace for arm Bring end-effector to pre-grasp position Move to object and grasp it Bring to pre-grasp position
Feasible Grasps Grasp width Object height Reachability Collision
Ranking of Grasps Distance to object center Grasp width Grasp orientation Distance from robot
Grasp Calculation
Checking for Collisions
