We propose a new algorithm for planning collision-free trajectories for a mobile robot. The trajectories of the mobile robot are described by uniform B-spline curves and these control points are optimized using the complex method. The complex method is very effective for this type of optimization of nonlinear problems because it does not require any computation of the gradient of performance index. B-spline curves have advantages for trajectory generation in that they guarantee the continuity of trajectories and the order of trajectories can be changed easily. Effectiveness is also confirmed by trajectory planning simulation of a two-dimensional mobile robot.
