Top speed?
Iʻve done a search in the forums and looked through the manual, but canʻt find any rules regarding a top speed for the robot. Just want to make sure Iʻm not missing anything. So is there a top speed for the robot this year? I donʻt think I remember any in past years either.

Re: Top speed?
There is no speed limit, provided you steer clear of <G37>. Obviously, the laws of physics also want to have a word with you before you embark upon your 50 fps drivetrain.

Re: Top speed?
Speed of light is the fundamental limitation. Sonic booms would probably be discouraged. Most likely, safety will be the determining factor - a 20 ft/sec robot may be deemed unsafe by the referees if it behaves as if out-of-control.
Maybe this year a speed limit will be established, which would be an "interesting" development for the program. Radar guns!!!:ahh: |

cool, thanks!

Re: Top speed?
Restrictor plates, just like NASCAR
.....look it up :) |

Another way to get "governors" to FIRST competitions?

Re: Top speed?
There could be a limit on the speed but I doubt that any robot could hit any dangerous top speeds on the short course.

Good luck trying to turn with a 30 fps drivetrain...

Re: Top speed?
i think the general speed limit will be limited by the laws or relativity :)
299 792 458 m / s that should be a general limit to how fast you can travel in the event (or at any time lol) |
Re: Top speed?
Like everyone above me said, there is no SET limit.
But most folks can't handle a drive train that's faster than about 15 f/s. Steering becomes really uncontrollable, not to mention the increased likelihood that you'll slam into the opposing player station wall, or the center field element. Good luck with whatever you choose! |

As to the original question, I think the general consensus is that after about 18 FPS a typical robot becomes very difficult to control and a real pig in a turn. Things like trick wheels, multiple motor drive trains, shifting gear boxes and real sharp PID loops could probably make 25 fps or higher controllable and useful, although at that speed your crossing the field very very quickly. It's an awful lot of design trade offs for that speed. But maybe thats worth it to you. If it's ever been worth it, this would be the year. I'd love to see a robot 'hotrod' that just throws every thing it has into a drive train of epic proportions. -Andy A. |

Re: Top speed?
We are definetly considering an automotive inspired steering system, but trying not to fall into making a go-cart, was more just curious for other teams sake, but I donʻt think we are going to put that much into speed...but who knows!

Seriously though, the top speed allowed is the speed in which you can still control yout 'bot. Anything beyond that will be 'unsafe'. This may also be the year for suction cups on your OI, as I can see the drivers stations taking some wicked hits. |
