Quoting Brady G
Awesome! I'm actually commenting because I'd like to ask a favor of you. We're building with NXT in a class at school and have challenged another student to a contest to see who can create the best moving part for our bot. We're using the basic bot that is built with the NXT education set, and need to make something in place of the "whacker" on the right side. I've come up with a few moving spinning blades, a few hammers and axes, but nothing of any compatability to the bot. Can you reccomend any tecniques, or even give me a basic design to use? Well, MOCpages will delete this if it gets too long, so tata!
Can you precise the robot's name so I can look it up on Google. I can't really understand what you mean by "whacker". Anyways, i'll try to help you. Simply tell me its name and I should be able to look up images on Google. Nice school man! People in my class have never heard of Mindstorms.
