Battery Buggy B

[shrewdPanther46]

I would also consider bushings, as they are considerably lighter and meant for high impact scenarios (braking). They are also superior for lateral loads, and provide much more stability while being cheaper and easily installed.

Any decent bearing will stand all of the abuse that a battery buggy will give it.
Bushings are definitely cheaper and on some set ups a lot easier to install. There are some very low frictions ones available in nearly any ID.

If you want to use plastic pillow blocks, PM me and I will tell you how to get them for free. My second prototype has a 10 mm bore that I am using flanged 10 mm ball bearings in. Would have saved time energy and weight if I had just gone with the plastic bore. With the weight savings, I now think that it would have been more effective.

What are you guys using for the frame?

[shrewdPanther46]

I am using thin plywood. I have seen metal chassis as well.

I got a score of a 100. Can I just bribe them with my solar panel pics? (Looking for a strong man)

At a competition or practice? Lol

My partner and I will share our results when we start testing. Hopefully we can all participate and help each other get better.

Hi,
This is my first time formally doing a Science Olympiad Event involving a vehicle. I helped with Scrambler last year, but I still have many questions.

1. Where do you get the motors? Do you just take something apart and use that, or is there some place/website where you can buy motors. Also, how do I decide which motor I should get.

2. What kind of wheels should I use? I know CDs are common, but I don't think they provide enough traction, so I am assuming they would drift.

3. What would a good run score be to aim for at states if you want to take first? The RI Science Olympiad does not have regionals ( we are a small state).

4. Did you guys (and girls) use wood or metal for the chassis. If wood is recommended, should I glue the wood or use a hammer and nails.

Thanks!!

Hello,
1. Take a look at the motors thread. There was a lengthy discussion about potential routes you can take with your motor selection

2. Same as #1, check previous threads. Try to find wheels with a good amount of traction, as they would help you avoid skidding

3. I'm not exactly sure what score to project since RI is not as competitive as other states, but I would say a score in the mid-high teens will probably be a good bet for first at your states.

4. Wood. It depends on the wood density you are using I think. We are using very thin plywood, so we are gluing. Depends on what your choice is.

The rules weren't specific as to if we could or couldn't use an Arduino does anyone know if we can or can't?

You are not allowed to use an Arduino. There are specified electronic parts that you may use.
