The Arduino Mothbot

Step 9 Build the Mothbot Body

The robot you're building is really no good unless it can hold itself together. For this reason it needs a body. I tried my best to make this as simple a construction project as possible. You are, however, going to have to do a little work on your own to figure out the right measurements. I suggest the age old "measure twice, cut once" method.

1. The body of the robot is made out of a small sheet of poplar wood I bought at the hardware store precut to 6" x 24". I cut mine down to 6" x 8" using the saw provided in the hardware store.

2. Next I drilled holes towards the front of the board to attach the servo brackets for each servo. For this I used an 5/32" size drill bit.

3. I also drilled in a hole at the rear of the board for the caster wheel that balances the robot. For this I used an 7/32" size drill bit. I chose to use a slightly smaller drill bit so I could get a tight friction fit with my caster wheel since I wasn't using a nut and bolt combination to attach it.

4. Then I attached the brackets to the board with the nuts and bolts. This was done using the flat head screw driver and the adjustable wrench.

5. After attaching the brackets I attached each servo to the brackets with the nuts and bolts.

6. Finally, I pushed the caster wheel into the whole.
