Robot model collapsing in Gazebo
Hello,
I am using ROS indigo in combination with the included Gazebo version. I am trying to control a robot arm in combination with ROS control in Gazebo. The robot arm I am controlling is the Kinova Mico arm. I am using the URDF model from the WPI Jaco package, however I needed to modify it slightly to be able to have the robot use the correct inertias for each link.
When I spawn the arm in a paused physics simulation, the arm spawns with all the joints in the correct position. However, when the simulation is unpaused, the arm collapses and all links jump to the origin of the world. I have a figure of this, however cannot upload it due to the lack of points. For the same reason, I cannot upload the URDF model.
I found a possible solution that said that the inertias are too low. The inertias for the different links are however in the order of 10e-4 so should be fine. At least, I believe the URDF model asks for inertia in kg*m2.
If any of you have experience with this or know a possible solution, that would help be out greatly. Thanks.
