Yellow Pipes and White Teeth

Max worked on picking up the yellow pipe today. The plan is to pick it up using axles that stick out of the front of the claw.

One of the biggest problems was making sure the arm was lifted to the correct height, so that the axles would go in the pipe's loop. But then we noticed that the claw could just slide up the ramp...so we wondered if we might not have to raise the arm at all. If it could slide up the ramp without getting stuck on the front, then the sticks would line up just right.

Max needed something to put on the outside of the claw, that was rounded enough to slide up the front edge of the ramp. Corrugated pipe, maybe? Or, Bionicle Teeth!

First, Max tried installing teeth by using Axle Pin 3s, but those let the teeth rotate, as seen in the above video. That might have worked, but then a second idea was to freeze the teeth in place by locking the axles with a thin beam 2.
