ha-ha it just turned out that we didn’t need them although now as I think about it we could have used them on the drive. We entered out first comp with it only using 6 motors:D
we our planning on going with a completely new design in the future because it was becoming hard to make it better.
Here’s it folded up and without big ball capability (and 6 motors)
In both of the two tournaments we have participated in, we have (by chance) ranked 6 in qualifications (the first one 4 and 0 the second one 6 and 0) and made it to the semifinals and both times had the potential to go farther but our alliance partners broke down.
Sorry, haha. Note the magically levitating buckyball.
I have a video of this robot (since we always end up being partners one way or another), but I’m sure Phillip probably doesn’t want me to release them…
It’s not available from vex but is ‘identical in every way except color’
we got it from here: http://www.omega.com/pptst/tygr.html
They sell it at about half the price but it’s only worth it if you want a particular color or want to buy in bulk (so that your net order including shipping is still saving you money).
I have finals coming up at my community college (I take a class there) so the full reveal will probably have to wait until after that.
So to keep you all busy; one more teaser.
Similar question, I see that the specs on the tubing from OmegaFLEX uses Shore A and matches the 35 from the specs on the VEXROBOTICS website. How do we know that the VEX product uses the same scale.
Clearly this is a cheaper alternative but given the GUM base I wonder if it is truly the same material.
Of course this would be up to the inspector at the event to determine whether or not it is the same.
We have used both kinds of tubing and have noticed absolutely no difference between the two.
Actually, I seem to recall a tournament where the team after us in inspection got some flak for using the black tubing (because the inspectors thought the amber tubing on our bot was the real stuff :rolleyes:)
One or two non-critical parts are missing from the robot in the photos so if something doesn’t look symmetrical
Drive:
four motors in HS configuration and directly driven.
we did have some little trouble going over the bump but it really didn’t make any difference.
big-ball picker-upper:
consisted of a fork-lift the brought the big ball to the top of the robot where it was fired by a wimpy catapult. the launcher also fired our preload over the fence right at the start of Aton (as seen in one of the teasers)
Bucky ball intake:
consisted of four one-way hinges that kept the ball in after the intake was lowered onto it. it could hold two balls
lift:
the lift consisted of two stages. the first stage raised the pivot point of the arm to about 16 inches above the ground. the second stage was the actual arm which had two motors geared in a 5to1 ratio.
