Continuous rotation Sonar Sensor

This is a simple Continuous Rotation Sonar Sensor, handy because it can sense in a complete 360 (excluding behind it, aka robot). I plan to mount two of these, one facing forward in front and one facing downwards. I'll post a video later.

I am going to use a 3.5mm headphone jack mounted below the sensor at the axis of rotation. With it being able to rotate a full 360, it doesn't have to go backwards to get back to it's default position, and it is faster than a standard servo.

One way I had considered solving this(as I was looking to do something similar) was running a self contained setup, by using a lipo, a uproc(08m or something of that size),pinger, ir emmiter for data transfer and something to detect position of the servo(wheel encoder). when the ir emmiter is aligned with the receiver, send data. The emmiter would have to be close to the center of the servo as to have the most amount of time in front of the receiver as the module wouldn't have control of the servo rotation.

Cool! And welcome back to your big, loving family, Krumlink!

Excellent Design Krumlink! All you really need is one sensor to do the job anyway. Yet some people put 3 or 4 Pings on their Things and let them Swing like Ding-A-Lings or ah Ping-A-Lings and still can't get enough coverage.
