After just getting back, I'm posting again. Here with a few things. One is an NXT Holonomic drive, which uses three "legs" to move around, check it out!
Also, I found a page where a team had two weeks to design and animal sort of robot, and they made a crocodile! It's sortof like CLGfive's robot, except it lifts its legs up, and moves them forward, using much gearing. Check out the website here, and a video down below.
