Video of 1114

Gravity is actually well known for its reliability. It just doesn't have a good power to weight ratio. And, of course, it depends on keeping the wheels the right way down.

Looks like the claw takes 16ish frames to fall, which is slightly faster than gravity alone for 78 inches. So yeah, the have something on there to help it along.

Sorry everyone, I got sick from all the traveling. The GTRC video's are uploading as we speak.

Thanks Bochek for these video's. Much appreciated.

It is a great robot although!

Why do you think it is illegal?

Looking forward to seeing video of the finals...

If you watch the video a long black like antennae comes well above the legal height limit. The rule states at no time can a robot exceed 78" during the match and if it does its gets disabled and DQ'd.

It does not allow for a mechanical breakdown or malfunction. It is one of the simplest rules they have with no grey area.

This is in the first video posted on this thread.

From this thread I have learned that the Simbots will never ally with the Poofs.

Otherwise they'll have to make a movie about what happens when Transformers and Decepticons get along, and that would be quite boring.

You should read the entire rule before calling them out.

As someone who was lucky enough to see this bot in person there's definitely nothing but gravity pulling it down.

I would love to see it in person or at least some close-up photos. Our lift carriage was sticking pretty badly at first due to all sorts of misalignments.

Well 18 frames is about how long a gravity drop from 78" should take, so I guess I must've missed some of the slower acceleration at the beginning. And/or it's not dropping a full 78".

It definitely doesn't drop the full 78". The claw's resting point is well above the height of a single tote -- the RC gets pushed upwards in the claw by the totes below it.

After some digging, I was able to actually get a pretty good understanding of their passive (-ish) lift. It seems like there is no vertical actuation of the tall lift at all that is only for the bin holder (it can go up by itself). It looks like there is actually some surgical tubing passively pulling the bin holder down (easily seen at ~30 sec in video), so that it can't "bounce" off the top of the stack while one is being made or when the stack is jiggling around. Also, when 1114 grabs a can, they have to first lift it to the height of 1 tote, which is actually done with the use of their normal "tote lifters" pushing their can grabber up while it is holding a can (at ~25 sec, little spinner is rotating to confirm the "tote lift" being run). It is not clear, at least from the video I can find, how the can grabber is kept at the 1 tote height after being lifted there, but there is a chance that there is a passive 1-way latch mechanism that locks it to (/above) that 1 tote height when the bin grabber is closed (dual use mechanism, can clamp on bins, and engage lift latch). The can grabber can drop all the way to the bottom and miss the latch because the can grabber is always open when it drops to the bottom, and (I presume) was designed to miss the locking level when the grabber was in the open state.
This is all just speculation as to what might be at work behind that beautiful red powdercoat, and it will probably be thoroughly explained when they post their robot poster for SideSwipe.

I am absolutely astounded by the complexity and simplicity that went into this robot, and the level of foresight that was paid to how this game would play out. Intaking fast and being able to sturdily handle a full stack seemed to have been top priorities for 1114, and they were definitely able to achieve them.

Here's the video that I referenced up there (Quarters 8): 2015 - Greater Toronto Central Regional - Quarter Final - 8
