查询词典 motion

This thesis establishes constrained motion model and sensor model of a mobile robot to represent mobility and perceptivity, respectively, and defines the k step reachable region to describe the states that the robot may reach. We show that the calculation of the k step reachable region can be reduced from that of 2k reachable regions with the fixed motion styles to k + 1 such regions, and provide an algorithm for its calculation.
