Re: Elevated Bridge 2009

I completely agree with chia on this one. Probably one of the more informational sites I looked at. Don't only look at the 5 steps to building a model bridge, but look at the other links as well. All of the pages are really good. Props to the guy that made that site. The maker of that site used to ...

Re: Robo-Cross (B)

I guess you have a very different threshold for reliability then I do. You broke five 12 tooth gears and stripped one clutch in 300 runs and you are OK with that? That is more then a 1% failure rate per run. 1% failure rate for the mechanicals is nothing compared to average robots operator failure ...

Re: Electric Vehicle C 2009

On my car, I have 2 servos spin one shaft. I had tried making them spin each wheel independently but that led to more problems than it fixed for me (car goes waaay off course even with corrections). But having two servos spin one shaft works fine for me. Ya I found out the hard way that using two i...

Re: Robo-Cross (B)

The design and testing of the robot is way way way more important than what yoru materials are in robots. That said expensive parts do give you some advantages. The thing I like the most about them is that they were very reliable to the point that I did not have a single part on my robot fail last y...

Re: Elevated Bridge 2009

Also if the glue is thinner it would be lighter. I am not sure if thin CA is lighter per unit of volume than thick CA but thin CA can be very heavy if applied improperly as it soaks through the wood so sometimes its hard to tell how much you applied unless you are doing it a few drops at a time. I ...

Re: Electric Vehicle C 2009

Uncharged bypass capacitors act as (sort of) short circuits for a very brief amount of time, causing a spike of current known as inrush current . A big capacitor would take longer to charge up, and so the current would be very high for a longer amount of time. BTW, 20000 mF would have been HUGE, ph...

Re: Electric Vehicle C 2009

So I am not actually going to nationals this year, :cry: but I want to do one event just to keep my problem solving skills fresh. I was wondering if anyone here had worked with stepper motors before. I understand how they work and they look ideal for this sort of application due to their low speed, ...

Re: Mac or PC?

http://www.quentyx.com/quentyx_images/ubuntu-logo.png All the studying I did last year for robot ramble and my ev (which was a horrible failure) got me interested in open source. I honestly like it much better than Windows. The only problem is that I can find drivers for a few of my devices but its...

Re: Robo-Cross (B)

I've seen one team get full points this year so far. (the team I am helping to coach... :D ) Though they still have a ways to go before they are doing it consistently. If you can even get most of the points you are doing pretty good though. I think this year is pretty tricky personally. Good luck ev...
