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).
