Cool new ideas for FIRST Robots - who has them?
Who has some cool new ideas for FIRST robots that they'd like to share?
Way back, a dog shifting transmission was a cool new idea. And likewise crab drive was a new idea, and so was holonomic. An easy to build 4-speed was a cool new idea more recently, and so was using a Dewalt drill transmission. Using the pneumatic kit parts to make a vacuum suction cup was a cool new idea. But lately, I haven't really noticed an abundance of cool new ideas. So, if you have them, let's here 'em! |
Re: Cool new ideas for FIRST Robots - who has them?
If I told you, I'd have to kill you.
But seriously, I've got a few cool ideas sketched out somewhere (what else are we supposed to do in english class?) for possible game components. I'll see what I can't scan in. Basically, there were a bunch of elevator mechanisms (mainly scisor-like) and suction devices |
Re: Cool new ideas for FIRST Robots - who has them?
I've got a few drive train ideas I'm working on, but they are only in the early stages. As far as I know I haven't seen what I'm thinking of before, but then again I haven't seen a lot :p .
I'm think it would be cool to see some climbing bots capable of more than what we saw for FIRST Frenzy (small uneven surfaces maybe?) but that would all depend on the field. The best way to see new innovations is for FIRST to throw us a curve ball next year. |

Propeller?
;) |
Re: Cool new ideas for FIRST Robots - who has them?
I can't recall if any team has done this - I know there has been a walking robot, but the idea I have in mind is more of a strutting 'bot.
I was able to visit Case Western's and the University of Michigan's robotics labs last year, and they both had cockroach-like robots which basically had six flexible legs shaped like Cs that rotated fully around. Three legs would always be in contact with the ground surface (the first and the third on one side, and the second on the other). It might not be the most efficient or defensive idea since there is not as much contact with the ground and such a bot can get easily pushed around, but then again, I guess efficiency and defense are really determined by the season's game :p |
Re: Cool new ideas for FIRST Robots - who has them?
I would like to have some more cheese in FIRST, LOL jk :D :D :D ;
but there are some ideas i have just beeing threw my first year of FIRST |
Re: Cool new ideas for FIRST Robots - who has them?
some of us are just waiting for the right time to throw out a omni directional, continuously variable drive trains...;)
|
Re: Cool new ideas for FIRST Robots - who has them?
omni directional drivetrains... like say, the mecanum wheel drive system.
Here they are... Jester Drive: http://www.chiefdelphi.com/forums/sh...ad.php?t=36079 |
Re: Cool new ideas for FIRST Robots - who has them?
sanddrag, if anyone really wants to spring something on everyone else, they won't say what it is or how it works, except in general terms. I have a drivetrain that I'm thinking about, but haven't drawn up or prototyped. There are other things cooking in various design areas, but I don't have pictures of them.

Well, sanddrag, you've seen my Cool Idea for the Summer (tm), the Planetary direct drive Wheel, however, I don't know if I'm ever going to make it plausible, and stable, let alone feasible. Jeff Waegelin helped me run the numbers, I think we're talking Dave Lavery's salary for a year for each one. :)

Re: Cool new ideas for FIRST Robots - who has them?
I'm working on an omni wheel drive train, using EL wire in all our electronic wiring (to give a really cool lighting effect) and I'm designing an absolutely amazing control system but i got to take the design to a metal shop to get a price estimate.
P.S. i have liquid electrical tape and I'm wondering if it is allowed on the robots. |

a machine shop will likely price such a project out, very very high. In 2004 we got a quote for how much it would cost to machine a transmission similar to the Technokats 2003 drive, and it came out at around $10,000 (No joke). |
Re: Cool new ideas for FIRST Robots - who has them?

$10K for that tiny transmission is a heck of a lot. They probably just didn't want your business so they gave you that high number so you'd walk away and never come back. I know it is all different parts and not a bunch of the same but still, it's not really that many parts and it's not really all that complex. |
Re: Cool new ideas for FIRST Robots - who has them?
I'm fairly certain it's illegal and it is not in anyway G.P but a robot that could trap others in it self and hold them.

Re: Cool new ideas for FIRST Robots - who has them?

Like normal plastic electrical tape, according to last years rules it would be allowed to insulate electrical connections only. |

I had once even thought of a robot that has really high traction and strong drivetrain. Then it has a hook and a winch. Then it could hook on to an opponent robot and reel them in to keep them from scoring. Or it could let them pull some line out if it wanted to. :D Of course it is porbably illegal and not GP and probably not incredibly useful because it would be a burden to the "fisherman-robot" too. |
Re: Cool new ideas for FIRST Robots - who has them?
i saw earlier that som eof you are looking at cvt's
well one year my team tryed to make then and it turned into a disaster the parts of it were al so heavy and then to shift it it is hard you cant just use a pnuematic unless it is multi positional but see wut you come up with, cause after all everybody has diff ideas...most of the time |

Re: Cool new ideas for FIRST Robots - who has them?
I don't know if anyone else did this, but last year our drive modules expanded by the force of a piston. They expanded 4" on each side.

Re: Cool new ideas for FIRST Robots - who has them?
I've been tinkering with a climbing wheel design(its like tank treads but on its own individual wheel)it kind of resembles a ferris wheel. I got the idea from an experimental WWI british tank design

Re: Cool new ideas for FIRST Robots - who has them?
How about this thing ?
I think it's a good idea that could use some refinement. You get the best of both worlds, push and omni. I think mechanum was the new thing on the scene last year, and it's still in its baby stages (Hey Andymark.biz - Mechanum Wheels... hint hint!!!). Mechanum makes a lot of sense if you want the holonomic effect with better traction and less complexity in the chassis design, but still boils down to the "makeability" of such a thing. People have done a wonderful job extracting maximum efficiency from all the given kit components while applying them effectively. The innovation levels have been tremendous. Necessity will bring innovation. I think we've tackled most of the difficult aspects of a carpet competition robot as far as the drive base goes. A lot of innovation gets overlooked in the manipulators. But makes no sense to design to the unknowns. |
Re: Cool new ideas for FIRST Robots - who has them?
I have a cool idea.

I don't really care who has them, I just care about the ideas themselves. |
Re: Cool new ideas for FIRST Robots - who has them?
i got to get a picture because i know you people will love it. on our arm to extend it we used a simple cable and pulley system. the catch is that the cable was this special toothed cable (looks like a normal cable but with a second cable kind of spiraling up the length of it) that fit perfectly into toothed pulleys. the benefit you ask. absolutely no slippage so instead of a bulky pneumatic setup or motor rig we had this thin cable. it worked beautifully. :cool:

Re: Cool new ideas for FIRST Robots - who has them?
yeah this is exactly what we used. it works like this. |
Re: Cool new ideas for FIRST Robots - who has them?
Now that is some cool stuff. I had never seen it before. What keeps the black cord from unraveling and how much load can this stuff take? How is the black cord attached to the silver cord?
|
Re: Cool new ideas for FIRST Robots - who has them?
the silver and black cord are bound together and coated with a clear plastic. they can hold alot of force but slack is REALLY bad its alot easier for the cord to come out of the pully then to put it back in. if their is no slack then your fine becuase its really a metal cable and really works smoothly with the pulley

Re: Cool new ideas for FIRST Robots - who has them?

The modules were all conected to a central point by hinging peices of metal together. There was one piston that ran up the center of out robot. When that piston expanded, it pushed on the central point causing the peices of metal to hinge outwards and expand the overall lenght of the 2 pieces connected to each other. Each module had its own 2 piece of metal that were hinged together that met up at a certain point. So when the piston pushed down, the drive module were pushe out of the fram of the bot. Forgive me if the explanation is bad. I am too tired to think properly. |
Re: Cool new ideas for FIRST Robots - who has them?
i want to see what people did with electronics. we realized the control board and the power board were the exact same size and mounted them back to back. we also mounted neon tubes to the bottom of the bot and used a nylon mesh tubing that is used in PCs to bind our electrical..... oh yeah and used magnetic limit switches to determine the exact angle of our arm (im thinking of trying a potentiometer for next year but i think the magnets are more reliable).

Re: Cool new ideas for FIRST Robots - who has them?
I personally have worked on this idea for a while- ever since I saw the 3 wheeled omni directional bot. I have been thinking, and I thought of a way to give the drivetrain pushing power- this has been the key problem in this design. All that I need is a game that would support the idea.
And also- The design is very secret... so I may not share it until it has been tested. |
Re: Cool new ideas for FIRST Robots - who has them?
I have a cool idea its basically holonomic with treads. Think omni treads.
Something ...... like this ![]() |
Re: Cool new ideas for FIRST Robots - who has them?
Santosh and i have been on IM allot and have been throwing around a cool design (among other cool ideas) for a treaded crab drive. I'm keeping the details to myself Santosh can share if he wants but its nice!
|
I do!
My A&P and other bio and life science classes have given me several interesting ideas.

Nice, the circuitrunners were considering that, but not only omni-treads, but also...TREAD-OMNIS. Hope that was forboding enough. We thought, we can put rollers on a tread, or replace the rollers on an omniwheel with treads thus creating something that resembles a barrel made of treads. you could drive a robot with one of these if you wanted, but two would give you tank treads and traction in on direction, and omni-wheel drive and traction in the other. The weight and complexity of the design that i came up with made it very impractical, but it was still very cool. |
Re: Cool new ideas for FIRST Robots - who has them?
here's something that I thought of last night... I don't really think it'd be possible, and if it were, the programming would be an absolute nightmare but anyway... instead of joystick controls, have the robot navigate by coordinates that correspond to a computer drawing tablet( that could easily be painted or marked to match the field) and the robot would be moving in relation to the stylus. :ahh: a step up would to even use a mini-mouse (with my thoughts, wireless would be best) instead of the stylus and then the buttons on the mouse could be used for robot functions, and here's where the wireless would come in handy, to make steering easier, make the robot rotate in conjuction with the mouse (front of mouse = front of robot) obviously, some type of omnidrive system(crab, macadam, or otherwise) would be ideal. :ahh:
Again, probably would never be possible, and if it were, it'd prob. take years to program, but wouldn't it be neat?!? |

Yes. Why what creature were you planning on mimicing?
