Any motor is variable speed as long as you change the applied voltage which a Victor does nicely (actually a pulsed output but that's another story). You may hook it up to a spike if you wish, but then it either runs full forward or full backwards which is bad for an arm manipulator.

hey doug, i have a quick question.

if your robot is just above 100 pounds and at the 4 foot limit, what other materials are you using to shed off extra pounds that your bot has? such as aluminum, fiberglass etc.

our robot is at 108 pounds, at the 110 pound - 5 foot limit and we still need a pnuematic cylinder to push our ramps down, leggings for the ramps and possibly another cylinder to lift the ramps

any suggestions?

I know you're not asking me but, I think lifting the ramps is unnecessary, since you would drop them at the end of the match. Leggings? how cold is it where you live?

I think a lot of our light weight is attributed to prior planning and composite materials. Composites have a pretty high learning curve, from what i've seen. We were lucky to have a parent that was experienced with it. We also design light from the start, so most of the structural stuff is kept as light as possible.
We still often get overweight by 10-12 sometimes more pounds. The first thing we do is look for any un-necessary motors or mechanisms, lexan that can be replaced with thinner stuff etc. It is not easy losing weight. Cheese holing is probably the last resort, it results in maybe 2-3 lbs lost.

Nice, 10 Victors !!!! Lets see, 4 in the KOP, plus six @ $125 (includes PWM and fuse) ....yowza that's $750 towards your $3500 limit. Hope you don't go over. Very neat layout .... good luck!

Wow, what are you guys using all those victors for?

[GO Groves 1213]

I know groves robotices (Team 1213) is using 9 victor

Ha, that thing is going to be a monster! Can't wait to see you guys at Davis.
