The Base, Shoulder and Elbow joints of the Robotek robot are fitted with a servo saver. The servo saver is a device that disengages when a robot joint is subject to an adverse force. The servo saver deliberately disengages to prevent damage to the servo motor. When the robot joint has been re-engaged, it will continue to operate as normal.
Identifying a Disengaged Robot Joint
A servo saver may disengage during use if the robot arm is restrained as it attempts to move. This can occur if the robot arm is held or if it is blocked by an obstacle.
If a servo saver disengages, the joint will become loose and will not move when a command is given.
Re-engaging a Robot Joint
While the robot is powered, carefully rotate the robot joint by hand until you feel a resistance and the servo saver locks back into place.
