Potentiometer Or Kinect

Can any tell me how to attach potentiometers with robot for teleoperation ?
Is kinect better than potentiometers ?

servo controller with potentiometer

@the original OP, were you able to accomplish this? what kind of potentiometer did you use? is it linear potentiometer or digital one?

That should work, but you haven't said what servos your using. Have you thought about running it through a arduino board. that way you could start by mapping the A/D from the pot to a PWM. But in the future you could put in some small code to calibrate the pot as well as adding more stuff. Plus you wouldn't been to biuld a cirtuit.

here's an idea -

If you can control your humanoid from a PC which has a webcam, then an alternative suggestion, which would be cool if it works, is "Hands gesture recognition" - http://www.aforgenet.com/articles/hands_gesture_recognition/

The article explains how to do it and even provides sample code - you then simply tie the gesture recognition output to your servo control software. You need to know C# although you can probably use similar code on linux using the OpenCV library. And if you have a roboard you might even be able to run it on the robot itself!

good luck however you choose to it.

I've been trying focus on the area of controlling my humanoid (upper body) with the movements of my own body. The simplest way i can think of is using an potentiometer linked to some mechanical/geared setup connected to my body. Do you think this schematic

http://www.epanorama.net/circuits/servo10v.html

is the best way to go or do you think it is possible to just send a 1.5 ms pulse input and use the pot internal to the servo to control my humanoid and make it mimic my movements. Or to you have any better ideas?
