We are still in the process of cleaning up the codebase and having all features of VT&R3 on the main branch.
- Main branch has support for lidar/radar teach and repeat.
- v3.0.0 tag has support for stereo camera teach and repeat (to be merged in the future).
VT&R3 is a C++ implementation of the Teach and Repeat navigation framework. It enables a robot to be taught a network of traversable paths and then closely repeat any part of network. VT&R3 is designed for easy adaptation to various sensor (camera, lidar, radar, GPS, etc) and robot combinations. So far, we have explored using VT&R3 to perform teach and repeat navigation using a stereo camera, a lidar, or a combination of stereo camera and GPS.
VT&R3 related papers usually focus on demonstrating one specific feature of VT&R3 instead of the whole system and require additional scripts to run experiements and evaluate results. Therefore, from now on, we will create a separate repository for each paper with instructions on how to reproduce the results.
The following articles will help you get familiar with VT&R3:
