Parking control of an active-joint center-articulated mobile robot based on feedback from beacons

This paper presents an autonomous parking control system for an active-joint center-articulated mobile robot. We begin by proposing a kinematic model of the robot, then derive a control law designed to stabilize the vehicle's configuration within a small neighborhood of the target position. The control law is developed using Lyapunov techniques and is based on the robot's equations of motion in polar coordinates. Additionally, a beacon-based guidance system provides real-time feedback on the target's position and orientation. Simulation results demonstrate the robot's capability to start from arbitrary initial positions and orientations and successfully achieve parking.
