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.

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?

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

Wow.....that is a great idea!

One of our brainstorming teams came up with an idea that looked similar....they called it the 'Monkey machine' because it could climb back and forth between the goals and manipulate the score at will......what a great concept! (also controlling the bar at the end)

Good luck......I can't wait to see your machine at work in the competition!

OK, I will tell you some of the honest capabilities.

• Everything you ever want to know about how we handle balls:

Because of the double intake rollers, it can suck in balls while robot is traveling at full speed of about 8 feet/sec (no problem even if balls are rolling towards or away from robot)

Theoretically, it can hold 12 balls. However, to collect 12 balls everything has to go right and it takes very long. There are two ball collection factors that we have to trade off - jamming and time consummed. The more we try to handle the more we have to be careful how they line up.

Although jamming can be an issue, we have a contingency feature built in if balls jam. The overlapping rollers of the extension can be retracted to unjam balls.

It can easily handle 8 balls with a 95% probability of not jamming. And it should take about 25 seconds if they are not too far away. It should take about 15 seconds if they are all lined up. Same when 'catching them from the human player. As the picture shows, the top door acts as a backboard for the human player who can just roll the balls over the top of the player station.

It can handle 10 balls with about 75% probability of not jamming. This should take about 40 seconds

With 12 balls, the odds of them jamming goes to about 50% and it could take a minute or more.

All times are rough and based on minimal interference from other robots.

We obviously will decide how many to pick up as we go. If there is minimal interference (such as may happen when a couple of bots are fighting on the ramp), then we can pick up more.

• Yes, of course we tilt almost flat to go under the limbo bar. All tilt positions are pre-programmed in software.

• We can hang and although we have not actually tried it, it can theoretically lift another robot along with ours. The linear lift / extension is the strongest we have ever had. No multi-section extension lift this year.

• One feature which is not obvious (not shown on in the picture) is that we have a mechanism to pop balls out of the goal. However, this was a last minute addition. So, it has not been tested while on the robot.

Overall, I think we will do well. We did not get anywhere near the practice time we needed because we had to go on a diet (I hope our scale is accurate because we are barely under the minimum).
