Stretcher Bot

So far in the two regional I have been the stretcher has not been used for stragaty. As we know the reason for this is due to the weight of the robot. I wanted to know if the are any other robots out there that can pull out the control panal and light to be used as a stretcher bot. I thought this would be something that some teams would do and I have yet to see another team with a stretcher bot.

We built a modular machine this year with reconfiguration in mind. Our controls, fuse panel, and wiring are all mounted on a single polycarbonate panel that is wired to the outside world through a 37 pin AMP (Mil Style) connector. A twist of the wrist and 4 screws removed drops our entire electrical system out. We can become a "Minimum Robot" with very little effort if asked to in a final. I wouldn't want to do this in the elims based on our recent success.

By this, do you mean with the robot on the stretcher? Because during one of our matches at UTC, an ally used an empty stretcher, and we (alliance) got it to the endzone for the 10 points.

The stretcher itself counts as a robot when its on the field... ergo, you get the 10pts and then 10pts if you have a bot on it.

I've heard much about the WPI stretcher bot. :) Or at least, you guys have been talking about it a lot. *grin*

Anyways, one of the other posts talked about Team Update #2 and the answer clarifying what qualifies as a stretcher bot. I couldn't find it in any of the team updates, and I was wondering if you have the exact statement from FIRST saying what a stretcher bot entails. (Is it just the control system, battery, fuse board, and an operating light?)

It's in Update #4

Page 2 - GM25

The "minimum robot" that may be used on a stretcher must contain the following components:

- Battery
- Robot Controller
- Radio
- Rotating Light
- Associated Wiring, Circuit Breakers, and Fuse Panel
- Team Name/Number signs

You guys need a light robot to pull around on the stretcher? We were pulling around our 130 lb robot from last year with our bot. Tank treads mean lots of traction.

we don't need one, we have one

WPI's robot configures down to just under 19lbs (majority of that is the 13lb battery) in under 30secs..

If we could get to a point where it would be strategically beneficial to become a stretcher bot, we could do so and virtually ANYONE could pull us..

manuevering that stretcher + 130lbs is definitely not as easy as stretcher + ~20lbs without a doubt.. and not that many teams that i've seen could reliably do it (analyzing their goal towing ability and such..)

It's just an idea.. it was pretty easy to make and a feature we'd like to see used at least once it the game :)

But knowing that each match we've been essential for playing is not a bad thing either :)

Our robot has this capability, as well, though we've yet to use it, as there has really been no need (we didn't actually design it for this use).

I'm not sure this is an actual benefit, as putting a control system, battery, and light on a platform with castors is not exactly the best way to learn about robotics.

It also screams "COP OUT" to me. *shrug*

maybe i'm wrong.

We designed from day one to have the Kid as a removable package to add to our strategic arsenal. The way that i think it's helped our team is that we had to plan things out and not just do it.

We designed a set of bus connectors so that the inputs could be safely and accurately be disconnected from the robot interface.

This is engineering at work my friend.

I'm sort of surprised that more teams don't have this feature, especially after that one update gave the exact "this is a robot" rules. We even went so far to build a little cage that we can drop our controls board in, just in case anything falls on us we don't let the OEM magic smoke out.

From watching the Great Lakes regional on Saturday, I was somewhat surprised that the stretcher wasn't used, even in the elimination rounds - if two teams were just going to sit in the end zone anyway, why isn't one of them on the stretcher?? Just my thoughts....
