Team 1132 Robot Video
 

OK All, here's some video of our robot (finally!)
Here's a few things to keep in mind:
Our pneumatics has a major leak in the vid, but we ran with it, so, our arm is not (i would estimate from our previous testing) even half of the speed and force it normally exerts. But, note our multipositioning :cool:
Also, we've treaded up our wheels (using a quickfix) so our system has improved turning. Oh, and dont worry about our manipulator bar, it's not done yet, but done enough to lift a tetra...
The footage was captured by one of our mentors with their Palm Zire. So, it's not perfect, but good enough.
Here's the links:

Nice job. I like your robot. You guys think about using a diffrent manipulator on the arm so that you dont have the tetras slip off?

Re: Team 1132 Robot Video
 

Actually our manipulator isnt done but by the time it is they wont be slipping off. Thanks! :D

Re: Team 1132 Robot Video
 

yea looks kool are you guys in your parameters for size requirments

Re: Team 1132 Robot Video
 

Things look good and I'm sure that the multi-position system in place for that pneumatic piston will be advantageous for things like grabbing tetras from the automatic loading station. If the chair in your video is a stand-in for that station, the method you used to grab the tetra would not work and the multi-positioning would need to be used.

Good work.

Yeah, we are in the size reqs. Our manipulator bar starts in an upward position, and locks down at startup.
Thanks for the positive feedback!
Any more questions?

Re: Team 1132 Robot Video
 

holy nut. guess we need a longer arm. that thing is gorgeous

Re: Team 1132 Robot Video
 

Can the arm go all the way up with a tetra on it?

Re: Team 1132 Robot Video
 

If you can cap a chair, you can cap a goal!
Do it! Do it! Do it!

Re: Team 1132 Robot Video
 

having seen the teaser pic i thought it was going to wobble and die tobe honest, but i am very impressed :rolleyes:
Well done... pretty amazing (and built / working :o)

Re: Team 1132 Robot Video
 

Yeah we can fully lift the tetra such that the base of the tetra is just over 8 ft high.
We can probably lift one of those chairs as well, if you'd like :D

I have read alot of comments from other users about arm length on other threads, so I wanted to explain the reasoning in our design.
We decided to go with an arm that could stack a few tetras on the center goal, but not be overly large. We wanted good control over them.
Rather than being "outcapped" we can get the center goal to our max height, then block it off. We've combined offence and defence in our design, and I think it's really going to help.
We finally fixed the leak in our selenoid last night, and we played with the pressure level. When our piston was run at 60psi, I nearly put a hole in my roof! :yikes:
We're now running it at 40psi, and that's a great balance for us (more video soon!)
Thanks for the comments!

Looks really good! Your arm is impressive! I was going to suggest a stop of some sort so the tetra didn't fall off but sounds like you already took care of that! Great video and audio too!
