How to callibrate the grippers

The grippers come pre-calibrated from fabric.

Howerver, by making use of them, they can uncallibrate.

If the gripper of one Fastbot is not able to grasp the cubes, this means that you need to re-callibrate it

Callibration procedure

This is a gripper that needs callibration

Turn it upside down

Remove the screw and the motor

Put the cube between the gripper fingers and close it as much as possible:

Remove the cube from the gripper and close just a little bit more the gripper fingers. Then connect to the robot by ssh and then send the command:

ros2 action send_goal /fastbot_1/gripper

Finally, screw back the motor on the top of the gripper
