Building a Robot

Physical Assembly

Assemble the base plate, motors, and wheels

1. Slide the encoder wheel onto the axel of the motors (Diagram 2) (optional)
2. Slot the support brackets through the base plate (Diagram 1)
3. Position the motor between the support brackets
4. Ensure the solder connection points are accessible
5. Push the 30mm M3 screws through the support leg, through the hole int he motor casing, then through the other support leg, secure with an M3 nut. (Diagram 3)
6. Repeat for other motor
7. Secure the 4x M3 8mm metal standoffs to the chassis using M3 8mm screws
8. Attach the caster wheel to the standoffs using M3 8mm screws (Diagram 4)
9. Attach the Battery box to the chassis using 2x M3 8mm countersunk screws + nuts
10. Clip the switch into the hole just infront of the battery box.
11. Using the thicker wires solder one red and one black wire to each motor, run the wires through holes in the chassis plate to the top side
12. Pass the wires from the battery box down through the chassis plate to one side of the switch.
13. cut the red wire so that you have just enough to reach from the battery box to the switch, solder the cut ends to the switch.
14. Solder the remains of the red wire to the other connector of the switch
15. Pass the red and black battery wires back up through the chassis on the other side of the switch
16. solder the 2.1mm DC Barrel connector to the red and black wires from the switch, red to the centre pin
17. push the wheels onto the motors
