Any plan to release a simple car model?

I want to do some simple navigation experiments, and plan to use a simple two or four wheeled car as the agent.

I found someone had the similar need (http://www.mujoco.org/forum/index.php?threads/implement-differential-drive-in-mujoco.3367/, and http://www.mujoco.org/forum/index.php?threads/modeling-wheels-troubleshooting.3571/). And I tried the xml file attached in thread 3571. But the car just keeps going forward, and cannot steer.

Can anyone contribute a simple car model? Thanks!

 

Thanks for your reply. BTW, is there an ETA?

 

Looking forward to an update.

I just uploaded a 4-wheeled rover model with ackerman steering and differential drive: http://www.mujoco.org/forum/index.php?resources/rover4we.28/
