I want to build small robotics. Anywhere I can get small motors and hydraulic-ram-like parts?

I’ll probably be pitting a humanoid (stands erect, two arms, a headsection) sort of robot against my friends in some sort of small battle. I’m pretty good with electronics and the arc welder, so construction isn’t so much an issue, but parts and programming would be. It’ll have to be remote control, and I’ve never built a remote for anything, especially not something with lots of options (arms, legs, weapons, etc). Any help is much appreciated.

It sounds like you’re doing your own version of Robot fighting league (http//botleague.net). you may want to look at their established system before creating your own.
when we build for RFL we tend to use either FM or DSM digital airplane-type radio controls from the RC industry. you can check out the Hitec Laser 4 or Spectrum DX6. They have 4 and 6 channels respectively. That’s two for speed and steering (or L/R differential drive), and the others for operating weapons.
You can look into robots that were built for battlebots or Robot Wars for building tips. Those team sites are mostly still active and love to talk about how they built their babies. Team Whyachi is a great one.
Motors are readily available. especially if you run of a 12~14v supply. then you can use automotive motors. linearactuators and pneumatics are tougher to come by. there are plenty available, but they are rarely found used and cheap. buuying new is expensive.
feel free to email if you need further help

  1. Sure. There is plenty of industrial automation stuff out there that’s just ideal for you. On a good day it will cost you around $1k-5k per degree of freedom for the motors, hydraulics, pneumatics and controllers. On a bad day it will be more.

    Count the degrees of freedom on your design, then multiply with a conservative $3k each and you know how much your robot will cost.

    e.g.

  2. Here is a link to low cost servo motors and controllers. Good for pre programed motions. You can use a hobby RC controller if you want real time control. Get a good programable one like a Futaba or JR. Just be sure to get one on a frequency of 27 mHz, or 2.4 gHz.
