libfranka: [communication_constraints_violation] error.

Hi,

Im currently having issues running any of the examples provided with the libfranka library. I have received this error on both the source install and ros install methods.

I am able to control the robot via the desk using static ip.

I am also able to complete the echo_robot_state and print_joint_poses examples.

Does anyone have any ideas where this error stems from?

 rosrun libfranka communication_test 172.16.0.2
WARNING: This example will move the robot! Please make sure to have the user stop button at hand!
Press Enter to continue...


libfranka: Move command aborted: motion aborted by reflex! ["communication_constraints_violation"]
control_command_success_rate: 0.78

Hi,

the avg in the ping test looks ok! The max is high and could lead to a performance loss, but the communication test should go through. When running the communication test, the robot should not move at all. This test just sends zero torques. Please bring the robot in a configuration like visualized here and try the communication test again. When the robot moves, make sure, that you compensated the gripper correctly.
