Team 100. We had really cool wheels with pneumatic tires. Traction was very good. You can drop the pressure and get more traction, or air them up and get lots more speed.

OMNI WHEELS :)


Manuverability of casters, traction of sharp metal things digging into the carpet.

I stopped and admired SPAM's drive and tread setup in Fla. What a bad dude setup!! nice work!! Also, for those of you who attended MMR and the WMR, 857 had the coolest setup! They are the guys using the chasis which has the wheels clocked at 120 deg and uses 3 separate joysticks connected together for control. As mannuverable as the crabbers and not as complicated. Can't wait to see what else the guys at RoboWerx have up their sleeve!:) Also, 67 the HOT team had some really sweet looking NC'd Flamers!!:cool:

Re: 45 Intimidation Picture....
 

Couple questions regarding treads as they are not a familiar thing to me.

First, do you ever notice any trouble turning? Circuit breakers tripping or motors heating or anything?

Second, specific to your design, what is that optical sensor for???

I think team 67 Hot bot had some Sweet wheels. They had flames CNC'd into them they look nice. Our rats wheels that we CNC'd out of wood looked sweet rolling (Chrome Rims:D :D ) But of course someone was smart enough to knock it off of the table and break the wheel so swe had to go to wheel chair wheels.

Turning can be difficult with threads if you dont do 1 or 2 things....

On the bottom of our robots we had a idlers that the chain ran against and these idlers had a slight "curve" to them...

Never had any problems with this design of tread...




The optical sensor was part of the "Traction Control" we had that we never used....

Re: Patrick....
 

Oh well, it was a learning experiance :)

Team 547 - Wheels built from scratch
 

We experimented with cleats this year. We built some prototype wheels and even a test jig with spring scales for testing traction. We ultimately settled on the cleated design you see in the picture. The wheels are 3 layers of 1/2" plywood with 1/2" C-channel aluminum for the cleats. They were definitely above average on traction but not as good as those beast machines. We could easily be pushed around sideways. We will probably try something else next year.

Not true

it was used a little bit, then the wire for the sensor was ripped, after it was repaired we used it once more and then it was turned off..

Hey did anyone see team 25's wheels

we had wheels w/ a 9in dia. and 4in wide we then

ground them flat and cut a criss cross pattern

our sponors called them carpet meshers (thats what they did)
