The connection socket for the ribbon cable from the hand controller is situated below the safety warning sign.

With the batteries now installed the bottom of the battery housing and base for the arm can be fitted by inserting the two lugs on the lid into the two slots in the upper case of the arm base. This is then locked by rotating the catch 90 degrees

The Robot Arm itself is now complete. Attention can now turn to the assembly of the Control Box.

The hand controller consists of a Printed Circuit Board (PCB) with a ribbon cable, attached to which are secured five spring steel contacts which are then in turn pressed down onto contact pads on the PCB by the switch levers held in the upper half of the controller case.

The five M3x12 tapping screws are used to secure the PCB to the lower case as well as to secure the spring contacts to the PCB

The Switch contacts are now screwed to the PCB in the lower half of the hand controller case.
The top half of the hand controller is held with its inner surface upmost and the switch levers are inserted.
The lower part of the case containing the PCB is lowered from above onto the half containing the switch levers and the two halves are secured together.

The finished arm looks good and functions well. It can lift a reasonable weight before the clutch (usually on the shoulder as it sees the most load) slips to prevent damage to the gear box of that function.

The parallel acting fingers of the jaws are lined with soft neoprene to allow them to maintain grip on smooth rounded objects.

The manual gives several suggestions for simple games to play with the Robot Arm, which are a good way to get used to the controls. Any number of functions can be operated together with the hand controller, if you can get your fingers around it.

Have Fun!
