Hi guys,
From time to time, my robot explodes or seems to roll unrealistically fast. The joints are in Torque/force mode with Max force set to 100. I tested with both bullet and ode, ode seems more drastic.
This post is related to exploding physics:

So should I try setting the hybrid operation? Or this is only true for IK modes?
Have not tried decreasing the max torque/force of the joints help either. Does it help?

Hello,
can you post your scene? The explosion can have many different reasons.
Cheers

Re: Exploding Robot
I small video showing the problem, not sure if this answers your question.
If you want I can send you the scene.

Re: Exploding Robot
Yes, the best would be to post the scene. You modified the robot. What exactly did you modify?
A robot, specially a walking robot, can be difficult to correctly set-up, there are many values that need to be adjusted and sometimes tweaked depending on the physics engine.

Re: Exploding Robot
All joints were set to torque/force mode and control loop was disabled.

Re: Exploding Robot
When I run your scene, nothing happens. It seems that there is no controller. How do you move the robot?
But other than that, it is stable.

Re: Exploding Robot
I am using an external controller.
The movements will be optimized from scratch (evolved by a genetic algorithm).
However, the physics needs to be realistic enough for it to discover realistic behaviors. I tried a different robot and it seems that no explosion ocurred.
I will try decreasing the max torque and report the results.
