This repo maintains the code for the NeurIPS 2020 paper:

Multi-Robot Collision Avoidance under Uncertainty with Probabilistic Safety Barrier Certificates
Wenhao Luo, Wen Sun, and Ashish Kapoor
NeurIPS 2020
[paper] [video]

Get Started

The algorithm of Probablistic Safety Barrier Certificates (PrSBC) is implemented on a modified Robotarium Matlab Simulator originally provided by Georgia Tech. https://www.robotarium.gatech.edu/

The code can be run with MATLAB 2014b and higher with MATLAB's optimization toolbox function 'quadprog.'

  1. Navigate to the root directory and run the "init.m" to initialize the addition of directories.

  2. Go to path "..\examples" and run the demo codes

    a) "main_PrSBC.m" to get robots swapping positions using centralized PrSBC
    b) "main_SBC.m" to get robots swapping positions using centralized safety barrier certificates from built-in Robotarium function
    c) "main_PrSBC_dec.m" to get robots swapping positions using decentralized PrSBC
