The Cellbots Remote Control mode includes a directional pad (D-Pad), a joystick, use of the phone’s accelerometer, and voice controls. Once the phone is connected you’ll have the option of chatting with the robot using Google Talk where you can simply type text messages such as ‘move forward’, ‘stop’, or ‘picture’, and have it obey your command.
Brain Mode also supports a web interface that you can access over the local wifi network to drive the robot with a mouse, touch screen, or keyboard commands. The phone on the robot will also use the camera to stream video to the browser so you can see through its eye from anywhere else on the local network.
The Cellbots app will also utilize the phone’s other capabilities such as text-to-speech to talk, take still pictures, get the compass heading, or show a personality on the screen. It is all open source if you want to modify it to support additional robots and functionality.
