ASSEMBLY
The following are suggested notes on the assembly of
the robot. This may be customized based on your
application needs


Tools and other materials required:
 Long nose / small pliers
 Phillip or narrow flat screw driver
 Soldering Iron for the Motor wires
 Solder wire
 Double sided tape or glue stick or other
adhesives
 Optional: extra nuts and bolts
 Optional: extra casing material for sumobot
protection e.g. thick plastic sheets, aluminum
sheets, ply wood


Before Assembly:

Prepare the base board.

Before proceeding, you may choose to peel off the protective cover on both sides of the acrylic base board. This will reveal the acrylic plastic underneath the cover. Do the same for the small motor brackets. Other users leave this on.

Solder the motor wires.
Insert the wires into the holes in the motor terminals and then solder the wires. Avoid overheating to prevent damage to the plastic or rubber materials used in the motor.

Wheel, Motor and Chassis Assembly:
Use the acrylic brackets to install the motor into the base board. Use the long bolt and its nuts to hold the motor in place. To facilitate neat wiring, the motor terminals face inward. The wheels may then be installed into the motor shaft. The optional encoder disc goes into the other side of the shaft if you will be using them. The caster wheel is installed with the brass stand offs

Electronics Installation:
Find a spot on the acrylic base board for the Saleng/Arduino Uno board and the battery holder to sit on. Double sided, glue stick, cable ties or nuts and bolts may be used to keep them in place. Install the motor driver shield on top of the Uno board. The pins should mate in alignment.

Microjumper on H1:
Check the motor shield and ensure that the micro jumper on header H1 is at the “One Pwr” position. This means that the power of the motors will be taken from the VIN pin of the Uno. This means that we no longer need to apply separate power at the VM+/- pins on the motor shield.
