Universal Robot Connector

[Sidney San Martín]

An important source of extra points in RACK & ROLL is robot lifting. To help avoid issues with teams breaking each other's robots, Team 555 proposes a universal latch design, one gender of which will be attached to lifter bots, the other to liftees. It should be sturdy and relatively easy to construct.
Opinions?
Ideas?

EDIT: The Unified Linkage Theory, perhaps?

I agree, this would be a great way for all the teams to work together to build our own standard, make the game run smoother for those participating, and give us a chance to learn more, too. However this plays out, I just would like to encourage as many teams as possible to get behind a unified standard.

I think this is a very good idea. But as with everything there are MANY ways to accomplish this, and as lifting a 100-120 pound robot is no short of a challenge, this may take some time. But we have to ask ourselves something, do we just want to specify the standard coupler? or should we go further and specify the position, and ways of lifting the other robot.

[Noah Kleinberg]

I had this same idea earlier. I think it makes sense just to have a design for the liftee end of it, and then that team can decide if they trust the other team's mechanism in each match.

I am in total agreement, I actually was going to start a thread about it, but you beat me to it

We all need to be able to carry a bot though so we could get the most points of 60. Requiring a lift of 300 lbs...unless you can use hydrolics and lift itself off the team that is picking it up. Many ideas that need to be dicussed, and desided on with every team! Lets all be one big team, and work as a functioning machine together

Also a question, if our robot touches the intertube at the end of a match, lets say on top of it, would it count as off the ground?

Good luck to everyone!!

I agree with you guys, a standard will greatly allieviate the challenge of lifting 100+ pound robots, but the implementation of the standard will be a challenge in itself!

If they use the same general ruling for "hanging" as they did in the Vex Challange, then the answer would be yes. As long as you were not phyically touching the floor you received the points. leaning on the posts or other robots was accepted.

No, you can't contact field elements or the driver station. Only other robots.

Good idea guys, one enormous problem you are all over looking. WEIGHT, Complexity of a latch of that type, and where the location of this latch would be on both robots. Also there are ways to lift the robot(s) using a smooth motion without much strain on the mechanics, so if done properly there is no need for a locking latch.

[Uberbots]

it sounds like a fantastic idea... but i dont know if i like it. i mean, what would we do if neither team in our alliance followed the standard? This solution is pretty much an all-or-none sort of thing- it only works if everyone participates.

We are just trying to come up with an assumes standard that makes use of what we can trust that every robot will have.

My captain and I have been bouncing ideas off of each other for a few hours, and if any of them succeed, getting the full 60 points should be relatively easy. The simplest way to determine if your robot could possibly get off the ground is if it would be able to climb a ramp, similar to the one in last year's competition. I can't exactly go into details about how it works (the specifics are yet undetermined), but I'll see what I can do once we've worked out some preliminary designs on paper and in Inventor.

[JamesBrown]

You really wont have much luck with this, look at the teams that have replied, they are from all over. The odds of you getting more than a team or two at you regional to adopt this plan are very slim. You would be much better off trying to develop a universal method to lift any robot you are assigned to work with. It is much easier for your one team to figure out a way to adapt to every one else that it is to get every other team to adopt one design. YOur idea is great in theory but I don't see it working in reality

[Lil' Lavery]

If you were planning on latching onto something, I'd suggest making it latch onto some sort of simple bar. Then bringing a bunch of those bars to your regional, and offering them to every single team who has the weight to put them on.

[Gerb4L]

Great idea guys! I have a question though: if a robot were to lift an alliance member by pushing up from below would this still count for the points? I was wondering because you have all seemed to be concentrating on lifting from above. I believe that pushing up from below would greatly simplify the problem.

Yeah.. USBCD36....

Our team also like the idea of a ramp/platform soultion. Let's fact it, all the bots will have the ability to move... If we could get some standardization on minimal ramp climbing ability/clearance requirements we could get some cool cooperative alliances.

A 4" platform with a short ramp seems more universally achievable than a 12" platform, which would need a much longer ramp for many bots. But, we do have the ability to specify a much more grippy ramp material, so it could be made easier than last year's ramp.

I see a new scouting class distinction here: Are you a Lifter or a Ramper?
