What's the most innovative/different design you've seen?

[JamesCH95]

What team has the most different or innovative design you have ever seen? Most powerful arm? Coolest drive train? I'm interested to see what's out there.

Wow thats awesome.

My vote goes to Killer Bees... looks likea very unique storage system and I cant wait to see how well its implemented.

Also team 1260's bot, Caution... 2 wheel drive?

Added: 229's shuttle/four bar is one of the most effective designs ive seen yet

Sorry, it doesn't do that anymore. We have a pitchfork instead.

The best tetra grabber that i've seen would have to be team 188.


It's a little biased, but team 357's drive train.
So far it hasn't been explained too well, so here ya go...

The drive train is a mecanum wheel hybrid completely manufactured by our team. The rollers are configured on 45 degree angles on our custom hubs. In order for the wheels to achieve their designed motion, each roller's bearings are actually molded into their urethane rubber material. The angles make an "X" pattern.

\\\ ///

Forward motion is achieved by driving all four wheels forward, the same concept applies for backward. Though there is a specific way to do it with these wheels, spinning can also be done in the traditional tank steering manner.

The translational movements are achieved on a screw principle. Diagonal wheels move in the same direction while the other diagonals move in the opposite. For example, the front right and back left move forward, while the others move backward. The roller configuration causes the robot to "slide" left and right.

These wheels can also achieve omni-directional movement: for example, spinning about its own axis while driving in an arc.

The mecanum wheel's rollers prevent the robot from being pushed freely like traditional onmi-wheels.

Would you like to back that statement up? I think of the many teams that have done a traditional omni-wheel setup, my team included, can contest that it does not move freely, if implemented correctly . I've seen many teams use them as free spinning casters, and that is not a 'omni drive' system. The fact that the wheels have rollers on them is countered by the wheels being placed at an angle 45 degrees with the chassis.

That statement was not meant to discredit the use of the traditional omni-wheel. I was just pointing out that the wheel design itself allows for traction as opposed to the free-spinning rollers on the traditional design.

Absolutely incredible.

Most innovative Drain Train - 357 Royal Assault - Those Mecanum (sp?) Wheels are sweet. They were out pit neighbors so I had plenty of time to observe.

Best Tetra Grabber - 188 Blizzard - That's one nifty tetra grabber they have. They can pick up two (maybe three) at a time and still drop only one.

Best Autonomous and best overall strategy/robot design - 365 MOE - They could cap the center goal in the home row AND knock off a hanging tetra all in the 15 seconds. And I thought their coach was really cool too.

(This one is a bit (a lot) biased)
Highest Robot with low CG - 226 Hammerheads - We have no troubles with the center goal, and can extend over 12 feets total. Even if we were to start to tip over, our chassis is so low to the groud that it's like a built in wheelie bar.

WOW



the coolest drive train thati have seen would definetly have to go to team jester there bot has custom designed wheels and floats butter fly and stings like a bee

At our Regional, lowest Ground Clearance was 980, 1/8" or less. Plus their arm could rotate a full 360 and had a revolving grabber at the end that could swing sideways into and out of tetras.

Most interesting strategic design was 842, they were all pushing, couldn't even pick up a tetra, but they had pushing power beyond all imagining and had brake panels they could lock onto their wheels. Finished ranked #3 seed despite their inability to score.

Another biased opinion, but our arm is a bit weird, it uses a pulley, a screw drive, and a pneumatic piston to reach a maximum height of 15-16 feet. The best part is we can hang a tetra on our arm from that height and still stay on our back 4 wheels (we have a 6-wheel rocking design).

190 has the coolest drivetrain ever! It can drive in any direction by just pushing the joystick. It's kind of hard to explain so I'll see if I can find a picture somewheres.

It's the same in concept as the picture posted earlier of 357's drive.
