Do you know the team numbers of any of these teams, so I can find the archived match videos?

Thanks

I know our team built one, but I don't think we ever used it outside of practice matches because the rest of our climbing system was just completely broken. It wasn't an original idea, but I can't think of any offhand, and the few teams I did search didn't turn up any interesting videos.

I did check the 2013 manual though, and there aren't any special exceptions to the bumper rules related to climbing or anything.

the rule in question is almost completely identical:

Re: Scaling via jack up legs instead of "hanging"?

The Team update (3.4.5 G19-1 & 4.7-R22 blue box) makes it pretty clear that it is not legal for 2016.

My interpretation of the 2013 rules is that it wasn't legal then, but then I was neither your robot inspector or your referee. The climbing rule was your robot could not be in contact with the floor & get credit so the bumper interpretation was less of an issue.

Re: Scaling via jack up legs instead of "hanging"?

Today's team update makes it pretty clear that jack up legs are not legal.

This topic is getting covered pretty thoroughly on the team update thread.

Additions include:

Quote:

G19-1
ROBOTS must be in compliance with
Section 4.7: BUMPER Rules
throughout the MATCH.
Violation: DISABLED

Quote:

R22 Blue box added.

This measurement is intended to be made as if the ROBOT is resting
on a flat floor (without changing the ROBOT configuration), not relative
to the height of the ROBOT from the FIELD carpet.
Examples include:
A.
A ROBOT that is at an angle while traversing a DEFENSE has its
BUMPERS outside the BUMPER ZONE. If this ROBOT were virtually
transposed onto a flat floor, and its BUMPERS are in the BUMPER
ZONE, it meets the requirements of R22.
B.
A ROBOT deploys a MECHANISM which lifts the BUMPERS outside
the BUMPER ZONE (when virtually transposed onto a flat floor). This
violates R22.

The second part of the R22 blue box seems to be a direct ruling on jack up scaling.

Re-Edit. Dagnabit. Sniped.
Edit: 100th post; woohoo. Only took me 5 years.

Re: Scaling via jack up legs instead of "hanging"?

Yep today's team update certainly clears this up. I feel like this is to the detriment of a lot of the more unusual/interesting strategies for navigating defenses (I expected them just to update the way a scale was scored) but at least its unambiguous now.

(Not that they also aren't if one is using the usual extend, grab, winch, hang method, amongst others).

Here is to just hoping that latching, grabbing, hooking systems used to grab the unique Bar & Scale the Towers are accurate, robust, automatic, and safe. (Manual unhooking allowance of said latches usually are recommended, as all robots are then disabled at completion of the matches and will not be powered up to effect any unhooking operation by the Robot Drive Team(s). Members).
