Robotics with the Board of Education Shield for Arduino

Mount the Wheels

Parts List

(1)  1/16″ cotter pin
(1)  tail wheel ball
(2)  O-ring tires
(2)  plastic machined wheels
(2)  screws saved when removing the servo horns

Instructions

The robot’s tail wheel is merely a plastic ball with a hole through the center.  A cotter pin holds it to the chassis and functions as an axle for the wheel.

  • Line up the hole in the tail wheel with the holes in the tail portion of the chassis.
  • Run the cotter pin through all three holes (chassis left, tail wheel, chassis right).
  • Bend the ends of the cotter pin apart so that it can’t slide back out of the hole.
  • Press each plastic wheel onto a servo output shaft, making sure the shaft lines up with, and sinks into, the wheel’s recess, then secure with the saved servo screws.
  • Stretch each rubber band tire and seat it on the outer edge of each wheel.

When you are done, your completed chassis will look like one of the pictures below.
