Hi all,
I made a robot(differential drive) which uses meshes as visual and collision elements. Robot executes a small to and fro motion for a small duration when it is inserted. When I apply velocity to one of the hinge joints, the robot moves rapidly; it goes up also. Here is the [video](https://youtu.be/vfdImQ9jsoQ). Why this is happening?
Here is [sdf](http://pastebin.com/48hjPv7s) file and [properties](https://drive.google.com/folderview?id=0B5du_0ymFMtvWjlwS2lOSmtBczg&usp=sharing) of each link.
