	Four motor crimps
	Four 9" lengths of 22 AWG wire
	Two motors

1. Using the wire strippers, strip about 3/16” insulation off of both ends of each wire.


2. Push the stripped end of the wire into the crimp hole such that the wire ends at the tab at the end of the cylindrical part of the crimp. Ensure that the crimp covers the full length of the stripped part of the wire and a small part of the insulated part of the wire. If the stripped part of the wire is too long, use the cutting surface of the wire strippers to cut some of the bare wire away.


3. Using the pliers, push down with as much force as possible on the one of the two tabs which make up the cylindrical part of the crimp. The tab should fold under the opposing tab and onto the wire.


4. Using the pliers again, fold the other tab on top of the already folded tab. Use as much force as possible to press the tabs onto the wire.


5. Test the robustness of your crimp by holding the crimp in one hand, and giving the wire a sharp tug with the other hand. It is much better to recrimp a wire at this stage than to have a crimp failure while the robot is operating!


6. Repeat steps 2-5 for the other three wires.


7. Push the flat end of the crimps all the way onto the Qwerkbot’s motors’tabs. The crimps may feel somewhat loose on the tabs – this is normal. If crimps are so loose that they fall off the tabs, use the pliers to squeeze the edges of the spade section of the crimp closer together.


8. To prevent shorting between the Qwerkbot’s two motors, please cover the metal part of the crimp and motor tab with electrical tape. You will need about ¾” inch of tape per crimp.
