I have tried to change the values of the ODE friction coefficients without perceiving effective changes. Moreover, I performed different tests varying the different parameters of the sdf solver within ODE, without success. The values of the inertia tensor were calculated from meshlab, and I even performed different tests varying them without solving the problem.
Related with this problem, I would like to know if there is any way of fixing a joint position whenever the speed is zero
Any help would be appreciated Tue, 18 Jun 2019 15:57:57 -0500http://answers.gazebosim.org/question/22960/sliding-model-in-a-wheeled-robot/Comment by kumpakri for <p>Hi, I have created a model of a wheeled robot and it is working, but during the simulation it slides on the floor even with a zero speed.

http://answers.gazebosim.org/question/22960/sliding-model-in-a-wheeled-robot/?comment=22989#post-id-22989Can you show us the code? A repository maybe? I remember having such problems but it always corrected when correcting all the physics parameters. I cannot remember any specific one that caused the trouble.Thu, 20 Jun 2019 07:32:11 -0500http://answers.gazebosim.org/question/22960/sliding-model-in-a-wheeled-robot/?comment=22989#post-id-22989Answer by Julien for <p>Hi, I have created a model of a wheeled robot and it is working, but during the simulation it slides on the floor even with a zero speed.
