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
