# gazebo_ros_control and effort limit

Hello,

I am trying to simulate an heavy robot (around 2 tonnes) in Gazebo. My robot is using wheels, these wheels are controlled by speed. The problem is that when something push my robot (not too much, so the robot should not move) the wheels (controlled to the speed 0) are moving (not sliding, I see them rotating). It seems that the velocityControl was not able to apply enough effort (to maintain the speed to 0).

My joints are continious joints. Declared with velocity_controllers/JointVelocityController. In the URDF I have set for my joints:

  <limit
lower="-2147483647"
upper="2147483647"
effort="2147483647"
velocity="0.5"/>


Even If I have read in the gazebo documentation that in the case of a continious joint, limits are ignored.

So i wonder if in the case of a VelocityJointInterface there is an effortLimit ? And how could I set it to a bigger value

Thanks.
