Motor Mount Assembly
For this step you will need:
2x Tires and Hubs
2x Motors
Motor Mount
6 M3 Hex Nuts
4 M3x12 Screws
2 M3x4 Screws
2x Opto-Interrupters
2x encoder Disk
Steps:
First line up the motors and insert screws from inside to outside, then tighten the nuts on from outside the mount as shown in the images. Do this for both motors, make sure the nub points out through the motor mount.
Attach the tires and hubs to the outside axles of the motor mount.
Now attach the onto interrupter
Arduino and Battery Holder Installation
For this step you will need:
Arduino
Battery Holder
2x M3x10 Countersink Screws
3x M3x12 Nylon Flathead Screws
2x M3 Metal Hex Nuts
3x M3 Nylon Hex Nuts
5x 6.3 mm Spacers
Steps:
First line up the M3x12 Nylon screws in their set positions on the Arduino as shown in the pictures.
Then rotate the arduino 90 degrees onto its side and slide the spacers over the screws
Now take the chassis and line up the screws with the holes in the chassis by rotating it 90 degrees as well so it can be slid into the holes on the chassis. Once they are in, secure it on the other side with the 3 hex nuts.
Put the Countersink screws into the top of the battery holder holes. Put a spacer on each screw, and mount it on the chassis, just over the motor mount. The Battery holder should not touch the nuts or screws of the motor mount
Motor Controller and Caster Wheel
For this step you will need:
Swivel caster wheel
4 M3 2 ended standoffs
4 M3x2 Metal screws
4 M3x5 Nylon Screws
4 M3x10 Nylon Screws
4 Nylon Hex nuts
4 6.3 mm spacers
Steps:
Put the 4 metal screws in the designated holes from top to bottom of the chassis, then flip it upside down. Screw in the 4 M3 standoffs tightly. Now line up the holes of the caster wheel to the other ends of the M3 standoffs and use the screws to secure the caster wheel to the the other end of the standoff.
Now place the four M3x10 Nylon screws on the top of the Motor Controller through the designated holes, rotate the motor controller onto its side, and slide the spacers onto the screws. Once again, line up the Motor controller with the rotated chassis and slide it in, making sure the dual H bridge is pointing to the right of the chassis. Now use the 4 hex nuts to tighten the motor controller to the chassis.
Line Sensors and Left Infrared Sensor
For this step you will need:
2x line sensors
10x nylon hex nuts
Line sensor mount
2x M3x4 Nylon Phillips Screw
2x 6.3 mm spacer
