Important Notes

The above schematic gives you a lot of information, but it still has some flaws, read the below information before you collect and build components:

Standoffs / Bolts Per Robot

• 3 x (2.5M x 25mm) standoffs
  • These are the stands for the base of the Pi
• 4 x (2.5M x 10mm) standoffs
  • These are the ones that are underneath the motor driver
• 5 x (2.5M x 15mm) standoffs
  • These are the ones with the screw on one end, hole on the other
  • One is to connect the pi to the motor driver in the corner closest to the camera
  • The other four are used to connect the Pi and PCB together
• 15 x (2.5M) bolts
  • These bolts are used to join everything together
  • 4 Underneath for the motor driver to the standoffs
  • 3 Above to connect the motor driver to the Standoff from the top
  • 3 Underneath to connect the long standoffs (The Pi ones) to the base (ONE OF THESE ALSO CONNECT THE WHEEL TO THE BASE, if unable to do so don't worry about this one)
  • 4 On the PCB to connect everything together
• 4 x (2M) bolts and 4 x (2M) nuts
  • This is for the motor mounts themselves
