Robot Oscillating Wildly When Attempting To Drive

Hey, so my robot is acting rather strangely when trying to control it. I have attached a differential drive controller. Driving forwards or backwards in a straight line everything works fine, but as soon as I attempt to turn the robot goes crazy and begins wildly oscillating around the world. Any ideas on what could cause this?

I sometimes also get the same sort of problem when adjusting some of the joints

Thanks in advance!

I've seen this happen to the pioneer_2dx when excessively large torques are applied that can cause the robot to flip over. I would also try visualizing the inertia to make sure the parameters are reasonable.

If you are using an open source model and controller and post the details, we may be able to provide further debugging advice.
