Re: Be afraid... Be VERY Afraid
 
I'm going to guess that part of it is weight reduction. It looks like it could be made very light.

It also looks very compact.

One thing that makes it unique is that this allows for both independent wheel drive AND two speeds/torques w/o the extreme cost/weight/space penalty that would result from one using 4 AM2/Supershifters. Even compared to using 4 dewalts (not as tall but much longer in the wheel axis), it looks very space efficient.

It also looks like it is meant to be mounted through a hole in a sheet metal base/pan. Perhaps even a sheet of plywood or other flat material. Maybe this is to simplify frame design? (Just a pan with 4 wheel holes?)

Or maybe it could be mounted in a lazy susan (the missing part mentioned) and used as a crab module? There have been 2 speed crab drives before (I know 1625's done it) but they all used non-independent drive systems (1625 used two drive shafts with miter gears to drive 6 wheels, 3 per shaft).

Another aspect I see is that the Cim is off center. Perhaps some sort of a counterweight?

Last, Perhaps another benefit of the design is that if you tossed a tread on the wheel (if it had such a tread), you'd already have a spare wheel you could toss in. Then again, this "automated spare tire" effect is also

"Simpsons did it."

Err... I mean... is it a dual wheel rocker where each wheel is a different speed with an automatic shifter mechanism?

If i show the entire mechanism, there will be no guessing involved here... The point is to try to guess what that distinguishing component is. I don't believe anybody could do it, because of how out of the box it is. If it were easy, I wouldn't put $15 on it :P

In this day and age, if you have something "truly revolutionary!!!!", you should be busy writing a patent for it and not bragging about it on a forum ;)

Is the distinguishing component clearly visible on this photo (by clearly visible, I mean it is something we can see a decent portion of, it doesn't need to be shining in gold and covered in red paint)?

The distinguishing component is in fact completely removed from the assembly.

Suddenly, I'm missing the point of this thread.

Is it a gearless 2 speed swerve module?

It goes on the outside of the robot haha

Are you seriously that slow? You want us to guess on what makes this different, and yet you took out what makes it different...

Nope :p

Well it looks like it definitely flips in the direction of the larger wheel with the larger wheel traveling under to other side raising the small wheel way up in the air and flips the CIM completely to the other side...

IF NOT... just shoot me... LOL

Very nice guesses! The unit is indeed very compact and light; it needs to be, since there will be more than one on the robot. But the big secret here is actually much simpler than any of these great educated guesses.

It definitely doesn't pivot that much xD but I will not shoot you sir :(
