How do I monitor an angle?

Former Member

Hi all,

 

To say that I am new to robotics would be an understatement.  My first "mini project" is putting a camcorder on a turntable-style bearing.  The turntable has (will have) wires fed through the center, so I would like to limit the movement of the turntable to 360 degrees in order to avoid twisting up the wires.  I would also like to be able to find out the exact angle in which the camcorder is pointing so that I can chart the angle in an application.  From the searches I've done, it seems like the right tool is a absolute position encoder.  Am I on the right track?  Can anyone recommend a good product that I could use in conjunction with a turntable?

 

Thanks!

  • I would use a liner rotary potensiometer or some encode. Potensiometer is much cheaper. It would be good to use multiturn one. ten You'll ne able to mesure all 360 deg. As for fizical limitation can use something like spring with limiting sides. and a slider or a stick sliding just 360 deg.  do not know how to explane it
    I have drawned a ruf skech... As you see I'm not so good with paint imageimage
