Well considering worlds is less than 6 days away, I figured it was about time we released our robot. I posted an old picture of it here https://vexforum.com/gallery/showimage.php?i=5692&c=8
It uses 2 high strength and 4 two-wire motors direct-driven on the drive train and uses two high strength motors geared internally for speed on the scissor lift for expansion. We’ve also got a 3-wire motor for opening/closing our 11.5 in goal scoring mechanism. The most innovative part- we used pneumatics to power outriggers to prevent other robots from pushing us.
Please tell me what you think.
By the way, this robot has been built since October.
Sorry, the only picture I have of it unfolded is very old - before many modifications
http://www.youtube.com/watch?v=XgPQqE6Na24 - a match
[http://www.youtube.com/watch?v=f_In5yaEJ2k - driving practice
the match video starts after auton + this was before our new amazing autonomous came to be. Also we didn’t have our actual driver this day ( we were really trying to qualify another team) so this match is not the full capability of our robot
No, it is a simple ramp with a gate that we stick match loads on. In this picture, our controller is siting on it
We never tried linear slides actually, this was built long before those became popular, we actually adapted this from our original offensive design. Flip down extensions don’t help all that much - since the wheels aren’t on the outside, the extensions would act as levers for other bots to push against.
BWAHAHAHA! I love it! Never really liked wall bots due to the need for a competent alliance partner and that doubler/negater barrels can just be passed over you, but you have done a fine job here sir and I have no doubt you will always win so long as the interaction robot is foolish enough to get trapped in their isolation zone! (Not that he has much choice) Good luck at worlds!
It’s already holonomic … Using the scissor lift makes it so that other teams can’t ram us in autonomous and prevent us from expanding
It does have an H-drive
We try to avoid driving over game objects ( we have standoffs sticking down beneath it) since that would give the other alliance game objects back
With the way this drive is set up, mecanums would make it less stable. Also, this was set up and working before mecanums came out (our driver was used to it too) so we just preferred not to change it
wide enough so that a robot cannot get by on either side
very rarely, if we do we just strafe into the goal
I just found another video of it http://www.youtube.com/watch?v=iH3KHMEDJ1o&feature=youtu.be
This at the same competition so not the normal driver and the person handling autonomous was different so it didn’t do what it should have but overall we did what we wanted to. This video also demonstrates us using the outriggers ( when the ACME team tried to push us).
The only reason we let either of the other robots by us was because on of the refs started to count for pinning
