Motorized Camera Slider (with Object Tracking) + Control APP

NEW CAMERA´S CARRIAGE: Thanks Daniel for the feedback + collaboration   OBJECT TRACKING CAMERA SLIDER: Watch it in action: https://www.youtube.com/watch?v=VEQGMVY7RJQ This is a remotely controlled and Open Source CAMERA SLIDER with a tracking system. Two motors will be in charge of moving a platform where you can attach your smartphone/GOPRO or DSLR camera to and,at the same time, pan it tracking an object. Interactive 3D model of the camera slider here This camera slider can be EXTREMELY SLOW (0.01 mm/sec) but strong enough to smoothly move the camera platform You just have to let this Arduino robot know the location of the object to be filmed and it will calculate in real time what to do in order to keep the target always in the center of the camera view. Once the moving platform (with the camera) reaches the end of the rail, it will decelerate and come back to the original position, swinging back and forward until you decide to stop it. The camera can be replaced for a Webcam, flashlight, laser...  Remotely controlled using your smartphone or tablet (WIFI). The robot can be controlled from your own smartphone/tablet using the freely available APPs:  Android  iOS  You can even control its travelling / panning speed in real time. Perfect for Time-Lapse videos, to create artistic presentations, to show automatically different point of views during a webcam call/ demonstration video.
