Formation Control of Non-holonomic Mobile Robots - Tuning the Algorithm
- 432 Downloads
This paper presents the tuning methodology for the system of multiple two-wheeled mobile robots moving in formation. The procedure was applied to the trajectory tracking algorithm combined with collision avoidance based on the Artificial Potential Functions (APFs). Robots mimic motion of the virtual leader with a certain displacement avoiding collisions with each other and with circular shaped, static obstacles present in the environment. The results obtained during the computations are visualized to enable evaluation of the sensitivity of the closed-loop system to parameter selection. Then, the results of the simulation for the set of best parameters are discussed.
