 This game is absolutely *NOT* too difficult, but many teams will make it too difficult by biting off more than they can chew. - pfreivald [more] |

Team 1503's entry for LOGO MOTION, featuring a single-speed six-wheel drive, a single-jointed arm for feeder pickup, and a pneumatic pinch claw.
Deployment system and minibot were off for improvement at the time the photo was taken.

I neglected to mention that the robot's name is SPARDIS (Scoring Points At Relative Dimensions In Space).
More pictures from the final weekend of build can be found here.

There is a bit of a backstory to this robot.
After the 2010 season, we took a step back and evaluated it as a whole and looked at our mistakes. We discovered that last year we tried to do too much, and ultimately exhausted our design and machining resources to the point of actually never finishing our 2010 robot.
So, this year we set out with a goal in mind: Build the absolute simplest robot possible to play the 2011 game.
This is our simplest creation to date.
Also, even with our current minibot deployment mechanism, we're 15 lbs underweight.

The lightening in the arm support structure is pretty cool. Love the colors too.

I have to say I'm a fan of the little light up display at the top of the arm. Is this purely decorative, or designed to tell the Feeder what tube to give you?

It's a $@#$@#$@#$@# shame we won't be doing any double slamma jammas this year.

You will find that you will never stray away from this strategy ever again ... I think you will be very happy with your decision.
Good luck this year.

Nick, Pat, 1503, the robot looks excellent.
Any Plans to add a floor pickup mechanism?

Looks and works like a beast guys. Best of luck on the field this year, Nick. Show folks why you're one of the best drivers in frc.

From what I've heard, they don't need it.

This is what team 422 learned. Build a complex and ultimately failing robot in 2008, then build a ridiculously simple robot and win 2009 Quality Award and become 2010 Regional Finalists. Simplicity is the best design strategy, even in real life engineering.

Do the lights fade in and out upon teleop initialization? Does it make the oh so awesome TARDIS sound?

It takes a lot more force to do so with these flanged lightening holes.
These punches made the difference between having to swiss cheese a super heavy over-trussed frame and being 15 lbs underweight.

. If not for the mini-flanges, would the sidewalls be just bare sheet? If so, that would explain why the mini-flanges help so much.

All the pieces do have folds in them though.
Here is a photo of one of our practice bot siderails being made.
Here is a closeup of that siderail. After the first successful rail, we switched to an impact wrench to make things go faster.
Also, our bearings holes are punched in the same way. It's really neat, come take a close look at our robot sometime.

Re: pic: Spartonics 1503 - 2011
Holy reduction batman! Is that a rs755 mated to a cimulator mated to a gem 3 stage planetary connected to at least a 3:1 chain reduction? When i come up with solutions like this my team makes me sit in the corner. This year i had to power our arm with two rs755 mated with cimulator and a tough box plus 3:1 chain reduction to make up for the lack of gearing.

It works surprisingly well, but one thing we've discovered is that the GEM won't backdrive (the radial load from the gear it drives causes the output shaft to bind inside somewhere), so we use a big wrench when we need to move the arm without power.

Personally, after spectating at FLR, I'm still inclined to believe that we can be sufficiently effective without.

Aaaand 1503 proves you don't need floor loading to dominate at a regional.

I just finished watching the Pittsburgh regional. You guys did great! Very well done. Seeing you guys run with 1114 was absolutely amazing. You guys have a very solid robot. I'll be watching GTR for sure, can't wait to see how you guys do.
Best of luck!
