Battery Buggy B

Our spring was also getting chewed up, but we replaced it with a stronger one. You might think a spring would be less accurate, but it actually works quite well. It's an option, but there might be ones that are preferable. The only problem is that it slows down a lot, which gives us a worse score.

Edit: never mind, the spring does kind of mess things up. Hopefully not too badly.

How do you set up braking on a 3 wheeled car? It confuses me...

[Gemma W]

You have two wheels in front and one in back. Then you have the basic wing nut system in front. I think you were thinking of two wheels in back and one in front. The back axle can then be angled.

[scifipi]

Oh. Thanks! I never thought to do a one wheel in back car...

[Gemma W]

Yeah, it's kind of counter-intuitive, at first everybody else thought that the back was the front. It works quite well though.

What was the winning score in the Virginia State tournament?

Is there a way to make a four wheel buggy turn other than different wheel sizes and screw at the front? or a way to make it go straight, and then turn (around the bucket) and the go straight again?

[Gemma W]

There are many ideas and discussions near the beginning of this thread. However, I think that only turning around the bucket would be more efficient but extremely difficult. It would be much better to go with turning the whole way.

[Epicfail]

Well, couldn't it be done with like, 4 micro switches? (after certain distance, micro switch activates, car turns, another activates, car turns again [so it faces straight] then goes straight)

[Gemma W]

I guess. I hadn't really considered that, but if you can figure it out, go ahead. Just be careful with time, I don't know how long you have until your next competition, but make sure that you have enough time to do it and test before you start.
