When I send the cmd to ros topic /cmd_vel as follows:
rostopic pub /cmd_vel geometry_msgs/Twist
“linear:
x: 0.0
y: 0.0
z: 0.0
angular:
x: 0.0
y: 0.0
z: 0.1” -r 10
At beginning the robot rotates as I want, but after several weeks, the robot cannot rotate anymore, but just move backward.
In this case, is there any motor damage or gear box damage inside Panther? and how can I fix this?
