Let's start a new thread under this thread for each machine bold enough to post photos of their robot.

Under the each thread, let us all ask questions, analyze the photos, and generally make educated guesses about the various machines.

Okay this is what I see:

4 wheel drive, wheels in the corners. Front drive uses Fisher Price motors. Rear drive uses drill motors.

3 pivoting joint arm/ball grabber. PLUS --- A turret. 4 jointed arm. (I hope they have good drivers and lots of practice time ;-)

Gets up on the bar (or at a minumum can hold itself off the ground, I suppose they could have lifted it manually).

First-In-Last-Out ball collection and delivery system.

I guess that it can perhaps hold 5 balls, assuming no ball jams.

Looks like they had (have?) a weight problem with all the lightening holes.

Perhaps there is more.

If you have ideas or thoughts or contrary opinions, please share them.

Big ball capacity: 8? more?

Sucks them off the floor.

Do they enter the basket from the bottom? Maybe yes. Can't quite make it out.

Classic Beatty Drive System: 2 wheels on one side of machine, casters on opposite side.

Powered Wheely bar? Perhaps a lance to keep off would be ramp sitters? Maybe multifunctional arm.

I have not quite figured out how or wether they get under the 30 inch bar. I am leaning toward saying NO, but I can't believe it so I reserve judgement.

Looks like a linear lift of some kind gets the basket up to the dumping height. It is this linear lift that has me scratching my head as far as the 30 inch height. How do they get it low enough to get under the bar. Perhaps they don't.?

More eyes see more stuff. Please share your thoughts.

: Powered Wheely bar? Perhaps a lance to keep off would be ramp sitters? Maybe multifunctional arm.

Now what if this is a lever that allows them to start out 60' high, fall over to be under 30', gather balls, then the arms lets them get back up to the vertical position?

See above note.

Never put a sneaky trick past them! ;-)

OF COURSE! Now I see all (or at least more than I did prior)

Thanks Tom.

I'll 'eat my hat' if Beatty doesn't get under the bar. I can't imagine these guys compromising. It looks like the whole thing falls over (notice the wheels exposed 270 degrees and the white plastic blocks on the front middle) and then that arm facing us props em back up. Actually, now that I look closer it kind of looks like there are two little casters above those white blocks . . .this picture is soo hard to work with though.

4 Wheel Drive -- drill motors, one per side, chain links front and rear wheels.

2 joint arm, one linear up down, one pivot.

Grabber/arm looks to be a 4 banger with First-In-Last-Out ball routing.

Probably can spit the balls out up hill so that they don't have to lift their pivot above the 6 ft bar.

Can they get under the 30 inch bar? I guess not, but I could be wrong. Perhaps the 'bat hooks' fold down as they go under. Can't see it happening based on the photo, but it may be possible.

There linear lift looks like a set of duel racks (or perhaps sprokets walking up dual chains), one on each side of their machine. Raises and lowers their main arm joint as well as providing their lifting action -- very clever.

If you see I have missed something, or made a mistake, or if you have something else to contribute, do tell all.

2 wheel drive, drills (?) in the rear, casters in front.

Ball sucking loader.

Carries 6 or so balls (guessing)

Entire ball sucker/basket lifts via nested slides in rear of machine.

Low rider. Entire machine fits below 30 inch bar in starting position.

Looks fairly light.

Hangs? Don't know from the photo. Nate implies yes in a message linked to below

Nates Message:

: While I can't speak for the rest of the teams, I can give out a little info based on the finishing touches that I just put on the control program...here's just a few of the things that will make the Mystery Machine rather interesting this year...
: - 2 joysticks, 8 buttons, and 1 multi-position switch connected to the OI
: - 8 speed controllers & 5 relays
: - 2 speed drive train selectable on-the-fly
: - easily adjustable drive train for high speed/high torque between rounds without disassembly
: - mechanisms capable of performing almost all possible game actions
: - All aluminum construction
: ...all packed up in a nice and neat 30''x36''x29'' package.

If you see more or know more, please share your thoughts.

: 2 wheel drive, drills (?) in the rear, casters in front.
Yes - Drill motors on a no-chain drive

: Ball sucking loader.
Yep - Globe motor controlling 2 PVC rollers wrapped in rubber belting(see new pictures at link below)

: Carries 6 or so balls (guessing)
Would you believe 8 or 9 reliably? Check out the pictures...I didn't believe it at first either!

: Entire ball sucker/basket lifts via nested slides in rear of machine.
That center 'wall' on the basket stays behind, makes it easier to get the balls back out via same method

: Low rider. Entire machine fits below 30 inch bar in starting position.
Yep

: Looks fairly light.
I wish...we were busy making 'speed holes' earlier today, and might have to have a few more put in

: Hangs?
All I can say is see the pictures - 2 van door motors on a common shaft provide a lot of power for lifting, and thanks to the dynamic braking on the V883s, she doesn't like coming back down...

: If you see more or know more, please share your thoughts.

Motor Use:
Drive Train: Drill Motors
Basket Lift: FP motor with pulley/winch system
Infeed/Outfeed Rollers: Globe Motor
'The Hook' Positioning and Extension: Window Motors
'The Hook' Winch/Robot Lift: Van Door Motors
