The twinBot is a remotely controlled telepresence robot.
The GatewayApp starts a firefox session with Video/Audio WebRTC. Remote commands that are recieved in the browser as WebRTC Message will be transmitted to the twinBot control unit via bluetooth serial connection. The tricky thing was to build a bridge between browser and serial BT-Connection. We used a simple local webserver that runs as a service and is triggered by the website.

Wonderful.. congratulations! did you design the hardware too?

Smartphones are becoming the universal micro-controller that will eventually replace all
gadgets we are using today, and the trade secret will be b4x apps. :)
