Need sugestions on tires for my robot

Hey everyone, I am building a sumo bot and I want to make the wheels myself out of wood, now, as some of you may allready know, a sumo bot requires good traction and that is something that wooden wheels bring to the table, so here is my question, what are some good things to put on wheels that are like tires.

 

P.S I have allready thought about using rubber wristbands but as the dimensions of the wheel are 4cm diameter and 1 cm wide, this is not a possibility.

Homemade digital compass

Some time ago OddBot posted this circuit for a homemade digital compass based on hall effect sensors:

Compass_Schematic.jpg

Unfortunately CircuitBurn couldn't make it work. However I'm inclined to try again. A cheap DIY compass would be great.

So if anyone has ANY idea as to how this could be achieved let's hear it. It could be an improvement on OddBot's circuits or something completely different and wacky :D

Homemade wheel encoder

Basically I just printed out one of these (laser printer recommended):

encoder_40_s.gif

...And attached it to a wheel (double sided tape recommended).

Then I hooked up one of these (a 2$ IR sensor: QRB1134):

...And attached it to the motor pointing towards the wheel.

DIY CNC router project

04/06 Update

Motors and driver chips arrived in a package with some stuff for other projects today. Can`t find much information about the motors online and they have some marks on the body but they should work great. I`ll breadboard a circuit up to test the motors later.

DIY Picaxe 28x1 USB Headphone Jack Programming Cable?

Hi, I'm somewhat new here.

 

I'm in the process of building my first Picaxe robot based on the 'Start Here' Bot. So far I've recieved  my motors and wheels from Pololu and my Picaxe 28x1 Starter Pack from Sparkfun Electronics. Sparkfun said that a programming cable wouldn't be included, but they charged quite a wad of cash for one, so I bought the kit anyway since I couldn't find it anywhere else relatively cheaply like I could here. The only other one I found cost like $60.00!

 

This is a walkthrough on how to make a simple IR controller. It is relatively cheap and easy to make. Programming is simple since the picaxe basic already has … Read more

Amazing homebuilt quadruped

Searching for robot videos on youtube I came across this japanese guys profile. The quadruped in the video has a really interesting leg structure, not to mention the extra drive wheels. Check out the videos, it just looks and moves amazing!

Laser Range Finder MkII

This is my second attempt at a homemade laser range finder now with video. I nearly gave up after hearing about the Sharp IR sensors but I think this has potential as it focuses on an area the size of a laser pointer spot. The other sensors work on a much larger area. After a lot of frustration I've finally got all the circuitry working properly and hope to have a video posted as soon as I work out one last difficulty. Click on the photo for a full sized image. This is a work in progress, not a finished product.

Detects objects at close range. Can be used for object tracking.
