Ive always been interested in an idea like this. when i was 10 i built something like it...except everything was controlled from my bed, by strings (yes i did have to screw in 0-ring screws into my walls and ceilings, and yes my mom freaked out..but i still got to keep it
). i had everything controlled by strings. Even a bunch of boobie traps! (one would drop a bunch of jacks on your head, another roll bunch of marbles at your feet..etc.) I would simply pull the corresponding sting to make a boobie trap or other device work. But now, with the extremely useful help of this website, i think i can automate everything!
Thats the problem. I would go with some pulley system thats turned by a beefy motor ( controlled through relays by microcontroller)
Ive always wondered about that, i could never picture how you would hook up a high power consuming motor to a small MCU. apparently through 'relays' ...could someone please enlighten be on what they are and how to go about making or doing a relay type thing for lets say the $50 robot. or possible a couple resources?
