With this app you can control a robot or RC device by Bluetooth and see where it's going to. Just put an IP cam or android device with a streaming app (IP Webcam, IPCam or other apps with streaming functionality) on the robot\RC device. Type in the URL of the IP cam and connect to the MJPEG stream. This app is like the Stream-o-bot but not just for lego mindstorm devices. For example you can use it with an Arduino and a Bluetooth module attached to it.
