hi... i got a question
Admin:
all the parts are listed at the bottom of this page:
http://www.societyofrobots.com/robot_sumo.shtml
the servos are HS-225MG Servos ($28 each)
Specs of all Hitec servos can be found here:
http://www.hitecrcd.com/homepage/product_fs.htm
(just look for the servo you want, and specs will be listed)
You probably would want to get the Hitec HS-311 servo, as its much cheaper and much easier to get. I guess NZ is an odd place to buy parts . . . finding parts is often a pain even in the US, I think . . . :-\
If I was to use a motor, off the top of my head Id probably get one with no more than 300 rpm, and torque of maybe 24 oz-in. Id probably not use an encoder but instead use a tweaked fuzzy logic control system.
PID control, mathematical method for controlling robot motion:

Encoders, used for measuring wheel rotation:

ok I think I got all your questions answered . . .

ah i see thanks :D :D i can get a servo similar to the hs-225mg in nz for around NZ$30 (US$ 15-20) but i dont think it will be as small!!
do you know how to use picaxe and know the picaxe programming language? i just wanted to know so that i know if i can ask you specific questions about code, programming, etc

Annoyin Kid: seems like you are just getting into this great hobby... I might make suggestion that you consider buying a Parallax BoeBot as way to get into Robotics... Surprisingly, there are many folks from NZ that are very active on the Parallax forums and Parallax has very good tech support through their Austrailian and NZ Distributors...

It is funny that you mentioned PICAXE... I just ordered a few of the 08M chips! It seems like a great product and I am surprised that they have not gathered more strength and popularity here in the States... It is very very very similar to PBASIC (which is the language used to program Parallax Basic Stamps).
annoyin_kid:
yea picaxe is pretty good aye steve. picaxe has its own forum aswell - http://www.rev-ed.co.uk/picaxe/forum where there are lots of people to help out aswell.
