Please post video once you have the full test setup! I am sure many teams would love to see how a robot with trailer performs on the field and may not have the resources to build their own test trailer! Thanks!

I don't see any bumpers on the trailer. A realistic test in my mind would include the bumpers and whatever is used to mount them. Otherwise looks pretty good. However I'm more interested in how it will turn, but it doesn't look like you have enough to test turning.

The robot wasn't running at the time. This was taken during a strategy meeting.

Do you know what is in those batteries? acid and lead... Exactly. do you want that in your eye? Exactly.

your back wheels are not the FIRST wheels you cannot use those wheels only the FIRST wheels.

Read the picture description. I think they realize.

They know this; they mentioned it in the picture caption.

We just obtained 20 FRP panels today. After we get permission from our lovely principal to install them in the school's multipurpose room next week, Team 379 is welcome to come over and drive around if they need the space. We'll be doing the same with a widebody version pulling our trailer next week. We'll make sure to grab some video.

Geez, we get a new school and there's no room to put a full size field. I'd rather have our old, ratty small gym right about now.....

Re: pic: 379's test chassis and trailor on FRP

We'll have a chassis designed very soon. I would like to see what kind of pushing/pinning abilities you have on this floor do you think we could arrange a test like that?

take it easy, you telling me you ALWAYS wear safety glasses when your around lead batteries?

Re: pic: 379's test chassis and trailor on FRP

We haven't tried pulling a trailer yet, how's the actual pulling ability on the FRP? That's the one thing we've been curious about.. the acceleration without the trailer didn't seem to bad on the FRP, so I'm curious as to how it acts with the trailer on the straight line speeds.

Re: pic: 379's test chassis and trailor on FRP

Actually, these are AGM's (Absorbed Glass Mat), so it's just a solid mass inside the case. Even if you break the case (or indeed if you removed the case, as long as the contents were isolated from shorts), it would still work because it's all solidified into fiberglass and lead. No, you don't want it in your eye, but you also don't want to walk on the sun, and there's very little chance of either happening.

And for reference, I'm the guy who makes everyone wear safety glasses when they're FILING. I think the battery will be okay.

Re: pic: 379's test chassis and trailor on FRP

In the video, we have four individually driven "slick wheels". No bumpers yet, sorry. And in this case, we are all wearing safety glasses because the robot is running.

We will be testing a wide chassis today and adding weight for a more realistic evaluation.

Good God Glasteel loves you guys right about now...
Did you order direct or go through like lowes or home depot...
What did the final bill come to 600 + shipping?

Re: pic: 379's test chassis and trailor on FRP

LOL looks like the Robocats will save us from posting similar video. Now if we could only get together and record some vid of robots trying to pin other bots' trailers and such. Perhaps by the end of the week, we can.


They were all there in stock at Home Depot.

We're lucky to have a smaller field area - we'd have had to buy twice as much if we were constructing a full field like we've done at the old facility since our inception.

It's not a bad deal when you consider how many other local teams will use the practice area before (and after) ship. I'm sure other teams and organizations who build larger practice facilities and share with others arrive at the same conclusion.

Re: pic: 379's test chassis and trailor on FRP

yeah, but like for our team we only have 3 (lowe's fails) but its concerning me that we dont at least have any rolling frame with the new wheels because the team coach claims that we dont have time to build mock ups of two different designs to decide which is better...

Re: pic: 379's test chassis and trailor on FRP

Of course.
Didn't you get the memo that the batteries are always on the edge of exploding when they are not in use?!?!?!
They are made from plutonium & thus highly unstable. Don't dare breathe near them or risk a catastrophe with a 3-alarm biohazard alert!!


Edit: Btw, I forgot my sarcasm tags here... My bad!

Re: pic: 379's test chassis and trailor on FRP

no you just were safety glasses around the robot to start with runing or not, if you do it in the shop (or build location) you do it at events safety shouldn't be an act that we whip out at regionals but should be practiced at all times...
