Letting robots on top vs getting on top of robots
So, how many people will design their robot to be able to get on top of another robot (provided it has a small step or easy ramp or something of the sort). How many people are going to design their robot to accept their partner's wishes to climb on top of them? How high will the robots be in the end?

Re: Letting robots on top vs getting on top of robots
our team is going to let other team get on top. We are designing a deplying ramp system. Also we plan to make sure the robot can with stand at least 250 pounds on it.

We were thinking about that... and one thought popped up: Last year the game field had a ramp on it and a lot of teams couldn't get up. with this years field being pretty much smooth sailing, will anyone think to design a ramp-climber? |

I'm waiting for the Standards Committee to be formed to put out a spec for supporting and supported robots :) |
Re: Letting robots on top vs getting on top of robots
how about going around and capturing the other alliance's three robots and hoisting them up over 1 ft in your ends zone. Then allow your partners to also climb up....
you get points for robots over 12 inches- they lose penalty points for not vacating the end zone.... he he |

Actually they wouldn't be penalized. The rules state that if a robot is blocked while trying to exit the home zone during the end game they won't be penalized.

Re: Letting robots on top vs getting on top of robots
We want our robot to allow another robot on top, and to still have enough power to get ourselves, with them on top of us, on top of another robot.

Re: Letting robots on top vs getting on top of robots
I've noticed that the majority of robots are planning for others to go on top of them. If you are paired with another ramp-bot, will you be able to climb them if necessary, or will you both end up on the ground?
How funny would that be, 3 ramps that could climb each other! |
Re: Letting robots on top vs getting on top of robots
I think everyone here needs to think about the tast at hand. Think about last years game and how big the ramp was. now think about about how big your robot is, a team who carries 2 robots will probally be useful for only that because of weight issues.

I think a lot of teams are coming up with the same ideas, since a ramp is the easy kind of robot to build. You will definitely see alliances of three ramp bots, so sanddrag's comment is all the more notable - can yours climb a ramp too? Don |

For the love of all that is holy, people, please don't build robots that are micrometers short of the legal footprint. Go an inch smaller in all dimensions and you'll have a happier time fitting your robot onto someone else's, should you need to do that. |
Re: Letting robots on top vs getting on top of robots
Thanx for starting this thread our team 2028 was wondering about this, we're not quite sure how we're going to work this but so far have thought about letting people on us, or taking a few penalty points and setting ramps up for the other bots, it works out to be a significant amount gained. but we aren't sure

Re: Letting robots on top vs getting on top of robots
Our robot would be able to climb other robots we plan on using mainly the same drive train as last year but we plan on being able to let others get on us as well. Our robot would be able to do either or. Plus our drive train is a really powerful one so we could basically man up on the other teams top scorer and take them outta the match

Re: Letting robots on top vs getting on top of robots
We will be using a replica of a chassis we built in the off season.
After playing around with this chassis today, we found that it could climb a 15-20 degree slope. Keep in mind that this thing has a ground clearance of about an inch and was not designed for climbing. As to whether we will be climbing or climbed, we are not yet certain. But it is most likely that we will be focusing most of our attention on ringing. |
Re: Letting robots on top vs getting on top of robots
im pretty sure that my team is planning on trying to accomplish both carrying a robot and possibly if needed, climbing on another one. we plan on using ramp method.. as far as i can tell from our last meeting...

Re: Letting robots on top vs getting on top of robots
What about a 'bot that others could link onto, and then LIFT both of them?
Wouldn't that be interesting? Windwarrior Mentor-Team 17777 |
Re: Letting robots on top vs getting on top of robots
what happens with this poll if your thinking that your robot will do both???
|
Re: Letting robots on top vs getting on top of robots
I think the only real way teams are going to stack is by using a ramp system.
Not to sound too cynical or anything but lets face it I highly doubt any team is going to let another team try to pick up their robot with an arm. There's just too much that can go wrong and take them out of the competition. |

Re: Letting robots on top vs getting on top of robots
What about four long pneumatic pistons that would lift the bot so another bot can drive under it. It's easier than a lifting device. The rods would be in danger though, so the cylinders could push down aluminum rods that lift the bot. Once a bot is underneith, raise the rods.

Re: Letting robots on top vs getting on top of robots
I can tell you right now.... the ramp design for our robot is 0 degrees and can lift 2 robots 1 1/2 feet off of the ground. our robot is 4 feet 120 and has an arm, four wheel speed, and four wheel torque mode. Not sure if all in going to work since we are still in the designing stages, but it looks pretty promiseing. Anyway good luck everyone.

Also to teams building ramps, look at what material you plan on using and see if the surface (i.e. diamond plate) would make it easy or hard for a robot to climb up it. You can always cut holes and things in it to help with tracktion but remeber that some surfaces are still pretty slick. Not only does your robot have to support its own weight (if you plan on holding other robots), if you have a second robot on top, you are now holding up 240 lbs or so. Having another robot squish yours would be a very bad experiance so plan on making your robot robust. As for lifting robots, take into account the changing CG of your robot and the one you would be lifting. Also remeber to have a latching mechanism so when power is disabled the one you will be supporting doesnt come crashing to the ground. Hopefully some of these tips will help someone. Just thought I would share my thoughts and experiances. |
Re: Letting robots on top vs getting on top of robots
What about having a ramp and the piston idea. Have a robot drive on top of you then fire the pistons. The pnuematics can easily lift the max. 240 lbs. of 2 robots. Besides, I don't think three robots stacked on top of 1 is really going to happen that much.
|
Re: Letting robots on top vs getting on top of robots
Well our team had about a 45 min debate about if we should get robots on top of us or if we should get on to another robot.. after 45 mins we finally came to the conclusion that we would not be liftin other robots and would not focus on getting on top of robot but will try to be able to get on top of another one, but than again that was only a day 1 decision it could still change

Re: Letting robots on top vs getting on top of robots
As a note to all teams planning to build lifter/ramp bots, or debating the idea like us, two robots is actually a max of about 297 lbs, (2*(120lb robot + 15lb bumpers + 13.5 lb battery) not 240lbs.

Re: Letting robots on top vs getting on top of robots
In the poll, it asks if teams would rather descore/rescore spoilers than climb on other robots...is anyone taking that route instead?
I think it's really going to depend on the way that particular match is going, whether its more benificial to move a spoiler or to lift two robots... |
Re: Letting robots on top vs getting on top of robots
We were talking about this yesterday at our meeting and I think we're pretty set on letting another robot climb on us. Another teammate and I were working on ramp possibilities during physics class today. xD

Re: Letting robots on top vs getting on top of robots
The way i read the rule, it states that the lowest part of the robot is higher that 4 inches above the carpeted surface. This would allow a platform to be deployed and let a robot climb it and not on my robot. We are looking at a prototype and it folds back over our robot and the arm is still useful for the ringers. After we get to the home zone, we will deploy the platform with a small ramp to climb. It will have to be parked sideways. Still researching this ideal.
|
Re: Letting robots on top vs getting on top of robots
my own team personally thinks that we can have a platform on top so the other 2 robots can climb up like the ramp last year but have the platform double as an arm for ringers. i personally think the helicopter was much more doable.:ahh: :eek: :cool:

Re: Letting robots on top vs getting on top of robots
I've seen the idea of a helicopter pop up once or twice, so I just have to say this again:
At the end of a match, the two drive teams on the chopper's alliance who will be picked up turn to one another and yell (in a GOVERNATOR voice): "GET TO ZE CHOPPUR- NOW!!" The chopper team picks them up and says over a megaphone to the opposing alliance: "ASTA LA VISTA, BABY!" Now, back to the topic. I won't give away how our team is planning to pick up robots, but suffice to say that we want to passively pick up one to 4" (i.e. a ramp on top of our 'bot), and then worry about getting that one to 12", because that's more likely than two at 4" (hopefully one will be dealing with spoilers), and it's the same point value. |
Re: Letting robots on top vs getting on top of robots
I think this poll is inaccurate. For instance, we have the capability to lift one or two robots 12" off the ground, but if there is a better lifter on our alliance, our lifts are removable, allowing us to ge lifted. And if our lift breaks, we can hang ringers until it is time to be lifted.
