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. For more information see here: http://www.dis.uniroma1.it/~labrob/pub/papers/Ramsete01.pdf

chrigelburri | 3:92ba0254af87 | 16 | * This help class is for calculate and save the actual or desired value. |
chrigelburri | 3:92ba0254af87 | 17 | * There have the setter and the getter methode to change the value |
chrigelburri | 3:92ba0254af87 | 18 | * Is also possible to limit the translational and rotational speed |
chrigelburri | 3:92ba0254af87 | 19 | * by the value acceleration and thetaAcceleration. Therefore |
chrigelburri | 3:92ba0254af87 | 20 | * can adjust the ramp. |
