Request/Failure description

A broken screw (split in half) jumped out of the robot right leg.

Detailed context

When doing some experiments in current control mode, the right hip pitch made a sudden movement towards the limits (this behavior is being further investigated in robotology/icub-firmware#603).

Afterwards, a broken screw (split in half) jumped out of the robot right leg.

Additional context

No response

How does it affect you?

Not sure, we were able to run the robot calibration again. But we did not test anything else.

Hi! Checking the status of the robot, the situation is a bit problematic:

We will plan the intervention.

Hi @LoreMoretti ,
after @fbiggi 's mechanical intervention I tested the robot.
I did not have any problems either on the wiring or the software side; the robot started and calibrated successfully, the hip pitch joint works properly and moves in its full range of motion!

Closing!🚀
