Abstract: A method and a controller for controlling movements of a robot from a start to a stop position, where the robot has pairs of wheels having drivers that are controlled by local controllers. Based on a current speed and an angular position of each wheel and a position of the robot relative to the frame structure, a master controller sets up individual speed driving sequences for the pair of wheels based on the current speed and angular position of each wheel, current global position of the robot, and the start and stop positions of the robot. The speed driving sequence is transmitted to the local controllers controlling the pair of wheels, thereby controlling acceleration and deceleration of each wheel via the individual drivers. The local controllers ensure that pairs of wheels are kept synchronised.
