Simple Bots: Rolly

Step 2 Chop off the handle

Remove the handle from your scrub brush with a pair of cutting pliers.

The surface should now be made completely flat. Use your cutting pliers to trim off any remaining plastic. If that proves too difficult, you can cut off any plastic stubs with a coping saw (or hacksaw).

What is the purpose of mounting the battery and motor on the scrub brush? Is this to hold the internals in a semi fixed position within the ball so to create efficient energy transfer for locomotion?

It creates a smoother motion inside the ball than just throwing the motor in there loose.

It makes a vibrobot that moves the tennis ball
