VIS4ROB-lab / voxblox_multi_agent

Multi-agent version of Voxblox. Used in the paper "Multi-robot Coordination with Agent-Server Architecture for Autonomous Navigation in Partially Unknown Environments", IROS 2020

Multi-Agent Voxblox

This repository contains a multi-agent version of Voxblox. It is based on the original Voxblox implementation, with the additional capacity of fusing the sensory data from multiple robots.
This repository is used in a wider framework for multi-robot path planning, available here.

$ git clone [e-mail]:VIS4ROB-lab/comm_msgs.git # with ssh
$ git clone https://github.com/VIS4ROB-lab/comm_msgs.git # with https

ROS Nodes

The multi-agent version of Voxblox allows to use both the standard implementation and the modified one. In particular:

• To run the standard Voxblox nodes (single agents), use the executables: esdf_server and tsdf_server
• The executables that support the multi-robot pose-graph backend are: esdf_pose_graph_server and tsdf_pose_graph_server
