System and method for additive manufacturing and control thereof
Embodiments of robotic systems are disclosed. In one embodiment, a robotic system includes a tool used in a manufacture process on a workpiece, and an arm having an attachment point. The arm moves the tool, in multiple degrees of freedom during the manufacture process. A robot controller controls movement of the arm based on motion parameters to perform the manufacture process via the tool. A path planner component generates the motion parameters used to perform the manufacture process while avoiding robot collision conflicts. The path planner component includes a reach configuration component including data related to physical attributes, motion attributes, kinematics, and limitations of the robotic system. The path planner component also includes a collision avoidance evaluator to, using the reach configuration component, determine if an anticipated robot path results in any robot collision conflicts.
