The invention discloses a track teaching and
planning method of a master-slave mode multi-
robot cooperative
system. The method comprises the steps of: classifying the cooperative movement of the multi-
robot system into a
coupling movement and a superposition movement according to the relative movement
modes between the
tail end poses of the cooperative robots, and deducing the
constraint relation between the
tail end poses of the robots according to the two relative movement
modes; and determining the track teaching steps and teaching information of the multi-
robot cooperation according to the
constraint relation, and converting the cooperative movement tack planning problem of the multi-robot cooperative
system into Cartesian space track planning problem of a plurality of single robots so as to finish the track teaching and planning task of the multi-robot cooperative system. The track teaching and
planning method disclosed by the invention can be applied in multiple service processes meeting the movement constrain, for example, partial cooperative movement in complex
assembly task, carrying of large-size workpiece and non-fixture
welding process, and the like, so that the track teaching and
planning method has an extensive application prospect.
