Different designs
Depending on the robot version, the brake release unit may be located either at the base or at
the frame. The following two figures show the different locations.
The early design includes a brake release unit with or without push buttons, located at the
base. The later design instead includes a brake release unit with push buttons, placed together
with the SMB unit on the left hand side of the frame.
The different designs are not compatible.
