Multi-Robot RMPflow

This repository contains a python implementation of Multi-Robot RMPflow [2] and a 2D example for RMPflow [1].

Prerequisites

Python3
Numpy
Scipy
Matplotlib
The Robotarium python simulator (optional, only required for formation_preservation.py and cyclic_pursuit_formation.py)

To Run in simulation

2D example in [1]:

python3 rmp_example.py

A simple multi-robot go-to-goal example (centralized version):

python3 multi_agent_rmp_centralized.py

A simple multi-robot go-to-goal example (decentralized version):

python3 multi_agent_rmp.py

Formation preservation experiment in [2]: (the Robotarium python simulator required)

python3 formation_preservation.py

Cyclic pursuit experiment in [2]: (the Robotarium python simulator required)

python3 cyclic_pursuit_formation.py

To Run on the Robotarium

The Robotarium is a remotely accessible swarm robotics testbed. The Robotarium gives users the chance to execute the same code they developed in simulation on real robots. A user can conveniently run an experiment on the Robotarium's robots remotely through the Robotarium's web interface. Please follow the instructions on the Robotarium webpage to run the code on the real robots.
