Co-authored-by: Pascal Schade <165774906+pascalzauberzeug@users.noreply.github.com> * remove unused camera_card * rename and move max parameter * add default drive distance as constant * cleanup * first proof of sub-centimeter straight line driving * use wheels.pose in simulation so we can simulate slippage with rosys pull request https://github.com/zauberzeug/rosys/pull/146 * cleanup * stay as good as possible on the once defined straight line this was inspired by the works in #96 and makes that pull request obsolete * picked relevant code from #103 * ordered tests * better termination for straight line nav, rosys.sleep to fix flakyness and method split to prepare universal use * better variable naming * add test to ensure we can follow crops with slippage * fix yaw computation and use "drive to yaw" when following crops * fix tests --------- Co-authored-by: Pascal Schade Co-authored-by: Pascal Schade <165774906+pascalzauberzeug@users.noreply.github.com> Co-authored-by: Lukas
