Planning Maximum-Manipulability Cutting Paths [PDF]
IEEE Robotics and Automation Letters, 2020 This letter presents a method for constrained motion planning from vision, which enables a robot to move its end-effector over an observed surface, given start and destination points. The robot has no prior knowledge of the surface shape, but observes it from a noisy point cloud.
