If you’ve got a LEGO Mindstorms NXT robotics kit laying around, along with a couple of iPhones, then this robot might be a good weekend project. Video after the break. Click here for first picture in gallery.
The rolling bot above relies upon the Mindstorms NXT light sensor’s ability to read the contrasting colors on the iPhone display. After some simple programming and DIY tomfoolery you can drive the robot from the comforts of your WiFi-enabled web browser.
