Tells the direction of motion
The device uses 2 ldrs. It is programmed to check if any of them is low(I mean not receiving light). If so, then it checks if now the other one is low. Based on … Read more

Remote 3 Axis Camera Head with motion control

I`ve been wanting to build a mid size remote controlled camera head that has 3 axis and can be computer controlled and repeat its motion. I have a few RC helicopters that we build very basic 2 axis heads on, that work with servos and have a gyro to keep level.

The idea would be for it to rotate at about 300 degrees per second and to be able to feater in and out the motin for it to be smooth. I would also like to try to put some gyros on it, to stabilize it if it is free swinging on the back of a car or helicopter.

Motion Tracking from stationary observer

Hey guys..

I have an issue at my house right now...Young hoodlums of unknown origin have been sneaking onto my property and stealing things off my deck, and animals have been getting into my garbage.

 I want to build a robot that when motion is detected with a passive ir sensor, a webcam will activate and start recording, however I want the sentry to track the movement with some precision, since the target (hoodlum or rodent) will be of different sizes.
