Chassis Assembly
Strip about 2” from one end of each 7” length of 18 AWG insulated wire.

Mount the standoff in hole C, on the same side of the plate as the caster, using the 1/4” screw.

B A
For holes A and B, put a washer on a 1/2” screw and put the screw through the plate from the side with the caster. Attach a nut (on the side with the standoffs). Bend the stripped end of the wire around pins A and B as shown. Fasten between the washer and the plate. Make sure that the section of the wire next to C is stripped. Place additional bends in the wire to make an effective bump sensor.
Hold the plate so that the caster is on the bottom.
Connect one of the spare blue wires (from the light sensors) to A, wrapping the 3/8” tinned end around the screw and fastening it under the nut (on the opposite side of the chassis from the bumper wire). Connect one of the spare white wires to C, fastening it under the screw head (on the same side of the chassis as the blue wire).
Repeat the bumper installation on the other side.
Top Plate
The picture at the right shows the top plate as seen from above.
Note: this piece is not symmetric. Make sure that you are holding the piece so that there’s a hole in the lower left corner (marked by the star in the picture). If the hole is in the lower right corner, flip the piece over.
