hmmm i am not convinced they are too hard to build, just right now i spend my time on the 12kg bots, as there are more robots to fight in this class, but once i have a bit more time i will definately build some.
The way i tend to build robots is to find stuff lying aroud or in council cleanups and see what i can build with it and try and avoid spending money, I also find this gives me some interesting ideas.
When i get round to building a 1, 2 or 3kg robot (depending on who else there is to battle) i will most likely get one of the numerous radio control cars i collected as a kid and modify them into fighting robots.
I have two of those cybot drive systems (thanks to the council cleanup and i think they are way to small for a 2 or 3kg robot, you can buy a similar gearbox and motor from Jaycar for under $10. In fact there are two, both run 3v motors, one is a smaller one that i have used a few years ago for drive in an electronics project, bit small for a 2kg bot, even with some overvolting.
There is another gearbox and motor that is a bit more powerful, and can be set up for different gear ratios giving output rpm from 3000 to 2.9, so fairly verstatile looking and only $9.95. There is also two 12v motors with intergrated gearboxes on the end for $12 and $20 but at 70 rpm and 30 rpm they are a bit slow for robot use, unless you had some very large wheels, though that could be an interesting design!
From Dicksmith atm you can buy a 3.6v electric screwdriver for $10, i ahve one and pulled it apart (i will write up a better review soon) and it would be pretty good for robot use.
I think for a 1, 2 or 3 kg robot it has to be fast and powerful, the cybot drives or small jaycar gearboxes do not cut it for this, but the screwdrivers hold promise.
I also remember coles sells a full function 9.6v (with battery and charger) radio control car. This would have various useful bits for a light robot, or you could strap a weapon to it! The only drawback to this is controls as they do not have swapable crystals and only two channel.
Anyway these are a few ideas or thoughts of mine, there is plenty of other options, you just have to look around and think creatively about what you could use everyday available things for.
