2 wooden sticks, 3 film canisters, some rocks, a bunch of tape, 1 marker, 1 servo, 1 pot

Code:

Example code from class used.

Description:

The crawler has 3 points touching the surface at any one time for balance. The legs are old film canisters. 2 canisters are attached to the same rigid stick. The 3rd film canister is attached to one end of a marker, the other end of the marker is connected to the servo placed in between the other two film canisters. The crawling motion happens when any tow of the 3 canisters move toward one another. Small rocks are placed in the canisters to help the crawler from tipping.
