Step 2: Software

You will need:
Onshape (free account will suffice if you aren't making any new parts)

3d slicing software(Cura was used)

Arduino (completely free, needed to run programs on the bot)

Program to view dxf files(Adobe Illustrator works)

Step 3: Onshape Drawings

Step 4: Wiring Diagram/Schematics

This is a diagram of the wiring schematics for the bot.

Step 5: 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

Step 6: 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

Step 7: 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.
