Title
Franka Emika Panda Robot Electromagnetic Locking System (Brake) Replacement
Introduction
This guide presents a possible solution to the “Opening brakes fail” error on the Franka Emika Panda robot. A robot experiencing this issue will not unlock its brakes when commanded through the Franka Desk interface. It will unlock up to the broken joint then display the error message on Franka Desk. While attempting to unlock the broken joint, the robot may produce a weaker clicking noise compared to a functional joint.
In the following will use joint 5 (J5) as an example. By convention, joint 1 (J1) refers to the joint closest to the robot base, and joint 7 (J7) is the one closest to the end effector.
