Bump and Spin Chassis Essentials

Push the wheels onto the motor axels. There are flat sides on the axels
and there are matching shaped holes in the wheels. Make sure they
match up so that the wheels slide easily into place.
It is important that the wires from the motors are soldered to the
correct pads.
If they are wired incorrectly the buggy will travel
backwards or just drive in circles
. The bottom wire on the left hand
side motor needs to be soldered to the pad on the PCB labelled ‘C.0’,
the top pad on the left hand side motor needs to be soldered to the
pad ‘C.1’. The bottom wire on the right hand side motor needs to be
soldered to the pad ‘C.2’ and the top wire on the right hand side motor
needs to be soldered to the pad ‘C.4’. This is shown in the picture to
the right.
The red and black wires from the battery cage should be soldered to the pads labelled ‘RED’ and ‘BLACK’ below the
word ‘POWER’. The two remaining wires coming from the micro switches should both be soldered to the pads
labelled ‘SENSOR’. It does not matter which of these wires goes to which pad.
Using the provided M3 bolts, bolt the four 20mm spacers to the
underside of the PCB. Then using the remaining 4 bolts secure the
spacers to the chassis as pictured to the right. The buggy is now
complete!
