  • Abstract: In this talk we present our recent work on precise and accurate navigation of differential drive and omnidirectional robots. Our approach to navigation employs a novel parametric path model. It is based on quintic B?zier splines and applies optimization of the trajectory shape with respect to a user-defined cost function such as the time of travel. To ensure a precise execution of the planned paths, the paths are curvature-continuous and the planned velocities account for kinodynamic constraints.
    To further improve the positioning accuracy at pre-taught goal locations, we augment a particle filter localization with scan matching. This approach has been evaluated with an omnidirectional robot in a typical industrial task where we achieved an average positioning accuracy of 5 mm and 0.2 degrees.
