A video showcasing all the different features of the system.
Core Features
Trailer tracking system
A sensor system mounted on the loading bay enables reversing in environments where no positioning system is available. The system fuses measurements from a LIDAR and depth camera to estimate position and orientation of the trailer.
Motion planner
The motion planner efficiently calculates a feasible path from the starting position to the loading bay using a pre-computed set of motion primitives and a heuristic look-up table. The planned path is further improved online using a receding horizon optimization step.
State observer
An extended kalman filter is used to deliver a robust position and orientation estimate. The observer handles measurements from the external positioning system, internal angle sensors and the trailer tracking system, possibly arriving out of sequence.
ROS architecture
The system is fully integrated with the open source Robot Operating System, a modular framework for robotic systems. A GUI based on integrated visualization tools has also been developed.
