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

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?
