Put an Old Phone to Good Use–Make it a Lego NXT Telepresence Robot - lindseysamot1957

Do you have an old Android phone stored away that you keep only for emergencies–or just aren't sure what to coiffe with it? You could breathe new life into the semi-retired handset by strapping it up to a Lego Mindstorms NXT pose and turn information technology into a household security robot.

Wolfgang Beer mature the telepresence robot as a way of monitoring his home while he was away. The robot cruises around the house and gathers images, and uses an HTC Magic phone connected to the NXT robot kit. The Android phone works as a controller for the robot, which can receive signals ended the Cyberspace and transmit the commands via Bluetooth to the NXT microcontroller.

The actual automaton part of the build is pretty straightforward–it's ready-made up of a couple of bricks that holds the phone and and battery in put. The robot picks up the commands through a small nanohttpd server, which too serves a HTML5 controls page. The controller page displays the on-board camera, and childlike leading, down, left, and right-wing buttons for driving the robot.

Of course, while this is a goodness project to try unconscious for yourself if you have an Android phone handy, it does require a fair bit of steganography. Fortunately, Wolfgang has most of the code you leave need available connected his blog, or utile links to help.

Still, this is one pretty cool way of seeing what the cat is up to while you're kaput, or, if the worst does occur, at to the lowest degree startle a burglar into going away your property.
