This program is for an autonomous robot for the competition at the Hochschule Luzern. http://cruisingcrepe.wordpress.com/ We are one of the 32 teams. http://cruisingcrepe.wordpress.com/ The postition control is based on this Documentation: Control of Wheeled Mobile Robots: An Experimental Overview from Alessandro De Luca, Giuseppe Oriolo, Marilena Vendittelli.

chrigelburri | 0:31f7be68e52d | 22 | * |
chrigelburri | 0:31f7be68e52d | 23 | * This class controls the position and orientation of the robot. It has |
chrigelburri | 0:31f7be68e52d | 24 | * a run loop that is called periodically. This run loop reads the actual |
chrigelburri | 0:31f7be68e52d | 25 | * positions of the wheels, calculates the actual position and orientation |
chrigelburri | 0:31f7be68e52d | 26 | * of the robot, calculates to move the robot, |
chrigelburri | 0:31f7be68e52d | 27 | * and writes these velocity values to the motor servo drives. |
chrigelburri | 0:31f7be68e52d | 28 | * This class offers methods to enable or disable the controller, and to set |
chrigelburri | 0:31f7be68e52d | 29 | * the desired translational and rotational speed values of the robot. |
