This idea is very much a solution in search of a problem, and now there is a problem that is worthy of being solved this way. A robot that is cheap as dirt, but as smart as the average SmartPhone, with all the phones sensors available to detect collisions and tipping (accelerometer) and direction (compass) and position (GPS) and recognize objects and avoid obstacles (camera, possibly with the laser line structured light trick and with cloud services or even vision in the browser via OpenCV.js) all while retaining the WiFi connection to the net for true teleoperation.
