The configuration space of a robotic arm in a tunnel (1608.04800v1)
Published 16 Aug 2016 in math.CO and math.MG
Abstract: We study the motion of a robotic arm inside a rectangular tunnel. We prove that the configuration space of all possible positions of the robot is a CAT(0) cubical complex. This allows us to use techniques from geometric group theory to find the optimal way of moving the arm from one position to another. We also compute the diameter of the configuration space, that is, the longest distance between two positions of the robot.
