Multi-axis robot trajectory generation method and multi-axis robot controller

摘要

In a multiaxial robot, a path along which the end effector of the robot moves in the shortest time duration is generated. The robot includes a first link and a second link positioned closer to an end effector than the first link. Start and end points are specified, and velocity patterns are generated for joints driving the first and second links based on the specified start end points. The velocity patterns enable a movement of the second link to cause i) a reaction for increasing an acceleration force generated by the first joint when the end effector is started to be moved from the start point toward the end point, and ii) a reaction for increasing a deceleration force generated by the first joint when the end effector is stopping to the end point.
