2021-10-14 09:34:25 -0500 commented answer Nonzero joint velocities for static position

Well, it depends on how much non-zero it is. I have 0.1 rad/s, which is pretty high deviation.

Nonzero joint velocities for static position Hello everyone! I am using ROS Melodic with Gazebo 9 and working with Unitr

Hello! Could you finally solve the problem? I get the same serror

Hi all, I'm using libgazebo_ros_ft_sensor.so plugin to find torques in joints and control joints using gazebo_ros_control plugin. However when I compare joint torque from sensor and position_controller/state/command value (result of PID work), they are not the same. Their behaviour looks similar but as if sensor value n times smaller than command value. What could be the reason? Thanks!

Hi everyone! Seems that the solution is found! The issue was that i set high friction and damping coefficients in joint.

Sensor uses GetForceTorque function of gazebo which provides values in SI as I expect. ros_control generates effort as I
