MultiVehicle simulator (MVSim)

Lightweight, realistic dynamical simulator for 2D (“2.5D”) vehicles and robots. It is tailored to analysis of vehicle dynamics, wheel-ground contact forces and accurate simulation of typical robot sensors (e.g. 2D and 3D lidars).

This package includes C++ libraries, standalone applications, and ROS 1 and ROS 2 nodes.
