Simulation of DARwIn-OP in Webots

[fabien.rohrer offline]

Hi all,

I'm glad to announce that Webots 6.4.0 (mobile robotics simulator) contains a model of DARwIn-OP which can read the Robotis motion files.

I encourage you to take a look at these movies introducing our work more quickly than words:

If you're interesting to try out this simulation, you're welcome to download and install the FREE version of Webots from this URL:
http://www.cyberbotics.com/download
and run this simulation file:
$WEBOTS/projects/robots/darwin-op/worlds/darwin-op.wbt

The robot model contains principally:
- the 20 DOF of the robot
- the leds, the accelerometer, the gyro and the camera
- a realistic physics model (masses, torques, ...)
- a controller being able to read the Robotis motion files

Enjoy!
Fabien Rohrer

looks great!

any plans to run the DARwIn gait generator in the simulator?

Will It work for Bioloid Premium kit ? How ?

Thank you for your interest ^^

@limor: We planned to implement the gait generator soon. I keep you in touch through this post.
Fundamentally, everything is already there to do so. The virtual robot can be actuated precisely and the robot software is open source. The question is about wrapping the simulation to and from the real robot. We implemented a first controller reading the motion binaries to prove that this is possible. A second step is to increase the relation Webots-DARwIn-OP. But meanwhile, beginning to program the virtual robot is already possible. Everything helping us to increase this relation is welcome!
Using the Webots tools to generate gaits and finishing their calibration on the real robot is also an alternative which would be simpler to implement than the gait generator.

@MOHIT JINDAL: we have also models of Bioloid dog, KHR-2HV, KHR-3HV:

Feel free to try them directly on our software. We have no modules for the Bioloid kit, but modeling your own robot is easy through Webots.

I increased the height of my Bioloid mechanically and now i want to make it walk Will your software detect my long Bioloid or its just a software like AutoCad and Maya3d ?

@MOHIT JINDAL: I'm not sure to understand. Webots simulates robots graphically and physicaly. Several models are available, and can be easily modified. Modifying the size of a component should be easy to reflect on the virtual model. But don't except to have a magical detection of this, or to have a magical adaptation of the controller.

I implemented a wrapper to the Robotis gait generator. A movie depicts the DARwIn-OP simulation:

This will be included in the next Webots release, but you can ask me if you want the code before.

I advise you to download Webots and to create a account with the 30-days trial licence.
http://www.cyberbotics.com/download
http://www.cyberbotics.com/my_account/register

This allows to access all the DARwIn-OP features.
The project in included in Webots, but also open-source:
https://github.com/darwinop/webots-cross-compilation
(A similar file hierarchy is present in the Webots)

The startup documentation is available there:
