RobotsAnywhere NavCom (Android 4.0-4.1)

The NavCom app turns your phone into the brains of a robot that can operate either in telepresence or autonomous mode! You can use direct serial (on phones that have it), bluetooth, the audio jack or a standard USB cable to talk with the robot body.

One year after its publication, the original Android robotics project finally hits the Market. Use your phone as the brains of autonomous and telepresence vehicles on land, sea and air; control them with a computer, another phone, or even via SMS messages; get a video feed back even in 1G coverage areas. This has already been used across 9 time zones, including on public roads in two countries!
