This project focuses on three major developments:
i) To develop 3D SLAM module targeted for a UAV,
ii) To develop 3D collaborative SLAM (CSLAM) for multiple UGVs and UAVs,
iii) To develop 3D autonomous exploration algorithm for a UGV and UAV.
The single-robot 3D SLAM has been developed in such a way that a UAV is able to propagate through a single global feature map based on the information collected from a 3D depth sensor, an IMU and a stereo camera. In CSLAM for multiple UGV, the information of all sensors (depth sensor, IMU and stereo camera) are fused at each time step by the centralised fusion algorithm and the overall results are sent back to each robot. As part of the project package, a novel autonomous 3D exploration algori
thm has been developed for a UGV that guides the robotic system with a tremendous reduction in computational effort.
