Quickpost: WiFi Antenna With 360° Servo

Filed under: Hardware,Quickpost,WiFi — Didier Stevens @ 10:17

Last weekend, I’ve been playing with a RC servo to automate the recording of wsrradial plots. Metlstorm has presented a solution to do this with Lego Mindstorms, but I present a solution if you don’t want to use Lego components.

RC servos are easy to find, and you can find many servo controllers for PCs (a typical RC servo is controlled with a PWM signal). Though most RC servos though are limited to 180° rotations, there are 360° servos on the market.

Here is a picture of my 360° RC servo, togheter with a servo controller.

  1. Seeing that in action does look a bit scary, and I like that ;-)

  6. You can find it here: http://www.active-robots.com/products/motorsandwheels/servo-motors.shtml
    GWS 125 2BB Sail Winch Servo

    It’s capable of more than 360°, but can’t find the specs right now.

  7. with this servo you can set the position with a PWM rigth?… or is a continiuos movement one (setting the speed with a PWM)?

    I need to set positions.

    thx

  8. Correct, you set the position with PWM. But I had problems with my PWM controller, sometimes it would set the servo in continuous movement.
    I believe the e-shop I referred to has other 360° servos.
