Webots simulation, remote-control and cross-compilation for the e-puck robot.
Webots is an efficient 3D physics-based robot simulator that provides you with a rapid prototyping environment for modelling, programming and simulating mobile robots. The included robot libraries allow you to transfer your control programs to many commercially available real mobile robots, including the e-puck robot. The latest version of Webots comes with:
- several simulations samples for the e-puck robot, with both kinematics (based on ENKI) and dynamics models (based on the ODE library).
- many simulated e-puck devices: 3D accelerometer, differential wheels, proximity sensors, light sensors, wireless communication, LEDs and camera.
- a remote-control tool allowing you to monitor and remote control a real e-puck robot from your controller program over Bluetooth.
- a complete cross-compilation system allowing you to cross-compile your robot controllers and upload them onto real e-puck robots over Bluetooth.
Webots and the included e-puck cross-compilation tools, run on Linux, Windows and Mac OS X. The free version of Webots allows you to cross-compile e-puck programs. |

Rat's Life: e-puck robot programming competition
A new edition of the Rat'sLife competition started recently and will be running permanently. This programming contest is based on the e-puck robot and the free version of the Webots simulation software. It features two simulated e-puck robots roaming a LEGO maze and competing for survival. The robots can navigate the maze using SLAM techniques and recharge their batteries from four chargers. The longer lasting robot is declared to be the winner.
So far, a robot called Ratatouille is the best competitor with a very efficient vision-based SLAM algorithm and navigation system. Any student or researcher can engage the competition at any time and try to challenge the best competitors. Teacher willing to use this competition for robotics curricula are also very welcome.

The swarm group from the Bristol Robotics Laboratory has released, as open-hardware, the design of a Linux extension board for the e-puck robot. This extension board is based on a 32-bit ARM9 microprocessor and provides wireless network support. It runs an embedded Linux operating system, along with a Debian-based port of the root file system stored in a Micro SD card. The extended e-puck robot platform provides a powerful and flexible platform for experimental swarm robotics research. All design files, together with full setup instructions and code images, can be downloaded from http://lpuck.sourceforge.net . A reference paper describing the design and its applications can be found here

V-REP - the Virtual Robot Experimentation Platform - now includes a simulation model of the e-puck robot. The user can easily modify, adjust or rewrite the example control code to fit his/her own needs. The user can also easily compose complex simulation scenes by dragging-and-dropping new models or robots into the scene, allowing the e-puck to also interact with other robots, furniture, or custom-made models.
V-REP is a 3D robot simulator based on a distributed control architecture: control programs (or scripts) can be directly attached to scene objects and run simultaneously in a threaded or non-threaded fashion. This makes V-REP very versatile and ideal for multi-robot applications, and allows users to model robotic systems in a similar fashion as in reality - where control is most of the time also distributed.
Complex simulation can be created by making use of the various supported functionality, including:
- 2 physics engines support (Bullet and ODE)
- Full forward/inverse kinematics solver (handles any type of mechanism)
- Collision detection calculations
- Minimum distance calculations (mesh-mesh distance)
- Path planning (holonomic tasks in 2-6 dimensions and non-holonomic tasks for car-like vehicles)
- Proximity sensor simulation (exact minimum distance calculation within a customizable detection volume)
- Camera-like sensor simulation (fully customizable, with image processing capabilities)
- Various integrated edit modes (mesh edit modes, path edit mode, and custom UI edit mode)
- CAD data import/export (DXF, OBJ, 3DS or STL)
- Simulation data recording, graphing and export
- Various extension mechanisms (through scripts, plugins or a custom client application)
V-REP has various prices and licensing schemes. Students can use V-REP on their private computer free of charge. |
