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.

Installation

See installation documentation for all the details and options.

The easiest way to install if you already have ROS 1 or ROS 2 is:

sudo apt install ros-$ROS_DISTRO-mvsim

Then jump to next steps to see how to launch some of the demo worlds.

Launch demos

See more on first steps here.

Standalone:

mvsim launch mvsim_tutorial/demo_warehouse.world.xml
mvsim launch mvsim_tutorial/demo_2robots.world.xml
mvsim launch mvsim_tutorial/test_mesh.world.xml

ROS 1:

roslaunch mvsim demo_depth_camera.launch

ROS 2:

ros2 launch mvsim demo_warehouse.launch.py
ros2 launch mvsim demo_depth_camera.launch.py

Main features

  • Lightweight in memory, CPU and library requirements.

  • Fully configurable via .xml “world” files.

  • Headless mode, suitable for dockerized environments.

  • World maps:

    • Occupancy gridmaps: input as images or MRPT binary maps (from icp-slam, rbpf-slam, etc.)

    • Elevation meshes.

  • Vehicle models:

    • Differential driven (2 & 4 wheel drive).

    • Ackermann steering (kinematic & dynamic steering, different mechanical drive models).

    • Ackermann steering with mechanical differentials of full grade.

  • Sensors:

    • 2D and 3D Lidars: Robots see each other, their own bodies, etc.

    • RGB cameras

    • Depth cameras

  • Interface to vehicles: Custom Python interface, or ROS. Choose among:

    • Raw access to forces and motor torques.

    • Twist commands (using internal controllers).
