We are going to change this bot that has an eight tooth drive to a
24 tooth drive to make it faster.
The axle for 40 tooth gears for the wheels will connect into the second
hole on the beams.
The beams will connect into the sides of the motor with the 1 by 2
plates with the little shelves.
The bot is 12 studs long and we need a 4 stud platform for the motor
block we will use for the arm.
So having a 4 beam in back and an 8 beam in front will do.
To have strength we are using two of each on each side.
