Dual-arm Assembly Planning Considering Gravitational Constraints [article]

Ryota Moriyama, Weiwei Wan, Kensuke Harada
2019 arXiv   pre-print
It automatically generates the grasp configurations and assembly poses, and simultaneously searches and backtracks the grasp space and assembly space to accelerate the motion planning of robot arms.  ...  The assembly planner shall consider not only the pose constraints of objects and robots, but also the gravitational constraints that may break the finished part.  ...  By using this method, we can automatically compute a lot of candidate grasps using the CAD model of an object. Fig.3 shows some grasp configurations synthesized by the method.  ...
