Opis:: In the paper a path following problem for a wheeled mobile robot of (2,0) type has been considered. The kinematic model of the robot was derived with respect to the Serret-Frenet frame. Two kinematic control algorithms - Samson and Morin-Samson - have been tested taking into account their sensitivity to a white noise with a zero mean appearing in the one of state variables. The properties of path following errors have been analysed using statistical techniques. The conclusions related to an acceptable level of noise and a range of applicability of the presented algorithms have been reached.

Opis:: In the paper, a problem of selection of kinematic control algorithm for nonholonomic manipulator has been considered. For a nonholonomic manipulating arm, two kinematic algorithms - Astolfi algorithm (working in closed-loop) and Nakamura, Chung and Sordalen algorithm (working in open loop of control) have been compared. Simulation results have shown that influence of the dynamics on the behavior of mobile manipulator of (nh, nh) type is huge. It means that only kinematic control algorithms using feedback in the control loop are sufficiently robust to apply them in practical applications. Then, for the nonholonomic wheeled mobile platform, Astolfi algorithm, which belongs to discontinuous class of kinematic algorithms, has also been compared to a discontinuous algorithm proposed by Zhang & Hirschorn.

Opis:: In the paper a description of a manipulator relative to a desired three-dimensional path was presented. The path is parameterized orthogonally to the Serret-Frenet frame which is moving along the curve. For the path two different time parameterizations were chosen. The control law for the RTR manipulator which ensures realization of the task was specified. Theoretical considerations were illustrated by simulation results.
