Be afraid... Be VERY Afraid
If anyone can correctly guess what this is, I solemnly swear that I will send you $15.00 on paypal before kickoff. ![]() |
Re: Be afraid... Be VERY Afraid
So what's with only 1 CIM motor and the tiny wheel in the back? What's the use of this? Looks beautiful, but seems like you're sacrificing a whole motor's worth of power for an interesting design.
EDIT: It's a picture of CAD model. I'll take my $15 now. |
Re: Be afraid... Be VERY Afraid
I am afraid!
It looks like instead of shifting gears you are shifting wheels. I would love to know the gear ratios for each wheel. Beautiful design and beautiful CAD. I can't wait to see this on an actual robot! |
Re: Be afraid... Be VERY Afraid
is it a swerve module with some sort of shifting wheel assembly? are you going for smaller wheels for when you want more torque and less speed and then bigger wheels for more speed or something like that?
great job on the cad! can't wait to see what it actually is does look very menacing!:ahh: |
Re: Be afraid... Be VERY Afraid
Is it a 2 speed transmission where you shift which wheel is on the ground to shift the speed?

- the CIM motor isn't wasted at all - this is not only an interesting design, but a revolutionary one, in and beyond FRC |

Actually, new question (I'm sure you can answer this without giving away what this magnificent machine is) - Is the smaller wheel powered?

You're all surprisingly close :ahh: ... This does indeed have something to do with shifting, I'll tell you that. But there's something HUGE that you guys are missing, the same "thing" that will get you those 15 bucks :P

Re: Be afraid... Be VERY Afraid
I can't say what, but I can ask why!

Is this the completed assembly? Another guess of mine is that in addition to having different speeds, based on which wheel is touching the ground, you could have different wheel bases. So basically, in one orientation(likely the one with the higher speed) you have a smaller wheel base, therfore you can turn easily. On the other hand, when the other wheel is touching the ground(likely the lower speed), you will have a larger wheel base and therefor it will be harder for you opponents to turn you. |
Re: Be afraid... Be VERY Afraid
Oh good, now I don't feel so bad at looking at the CAD model (Which looks beautiful, by the way) and being absolutely dumbfounded about what it actually is. While the guess that it is a shifting wheel, as it stands right now it doesn't appear that either of the wheels are actuated (Might just be the angle).
I'm intrigued as to how this would be a revolutionary design both in and outside of FIRST. Perhaps once light is shed on its design I will be able to figure out how revolutionary it is. |
Re: Be afraid... Be VERY Afraid
What I'm really confused about is where is the motor/cylinder which changes which wheel is touching the ground. If there is no such mechanism, it would do really great on a bumpy field.
I don't suppose we could get a top/bottom view. |
Re: Be afraid... Be VERY Afraid
I propose three ideas.
1. Both "wheels" touch the ground at the same time. 2. The "wheels" aren't actually for driving. 3. The whole assembly pivots back and forth. This would work well for bumpy fields/ off road applications outside of FIRST. |
