This one talks about the remote functions to some extent.

Quoting from there ________________________________________________________________________

There's the obvious controls: left, right, fwd, backward, double-time quick. Then there's the not-so-obvious "training" button, which is the same as poking a tiger with a stick - it'll go into "battle mode". Then the "Stop" button has the 2nd purpose of also indicating what your Biobug's skill level is by blinking the eye LEDs. Another strange button is the "feed" button, looking reminiscent of a "Pacman" symbol. This has a dual purpose of "feeding" the button (very necessary just after the first bootup of the robot), and as a homing beacon. Once pressed, it continually broadcasts a signal for 3 minutes that the B.I.O. Bug can home in to. Range seems to limit out near 3 meters (10'), and the robots do an admirable job tracking the beacon. Each remote is supposed to only communicate with their own species of bug, but the manual suggests that other species can be aware of it as well. This has been confirmed, as other Biobugs are attracted to the "homing beacon" mode of differing remotes.
