What are some good cheap, silent, motors for mannequin robots and what kind of controller should I use?
I'm creating mannequin robots that require 24 motors: 2 neck, 4 shoulder, 2 elbow, 4 wrist, 2 waist, 4 hip, 2 knee and 4 ankle motors. The mannequins will be bolted via a horizontal post from the lower back to a wall. This means they can run, dance, and pose. I may also do something with the horizontal beam so the robots can do side flips, and moves like the twist, jumps and crouches. They will not stand up, but be bolted as I've described to a wall. They could even spin around completely to face the wall.
I've tried using 6v hobby servos for the joins. These are too weak for lifting fibreglass mannequin body parts. They are too loud. They also make noise when poses are held, and they drop and smash when power is shut off. I have been using a handheld remote control for testing with only 5 channels. The robot must be programmable though. Lets say the objective is to make a mannequin dance to 'Thriller' like Michael Jackson.
I am open to using kinnect technology as the controller (so that a dancer can simply dance in front of my robot, who can copy and remember) but I'm also open to controllers that allow me to force the mannequin into a pose at specific time codes in the song. If necessary, I am also willing to program the poses using some kind of lighting desk type controller (such as tech crews use in rock concerts to sync everything to go with the music).
I have noticed that a power drill or winch is very loud whereas my fan is very quiet. I live in an apartment in which neighbours can hear footsteps from other apartments. I would not dare turn on a drill at 4am because it would wake up everyone in the whole building, but I would have no guilt in turning on a fan. I need my robot to be as quiet as a fan. The voltage does not really matter for this project. I'm happy to use up to 240v from the wall socket.
Please let me know which motors and controllers are best for my mannequin robots, taking cost into account. Thanks so much for any help :)
