Im glad that you got it all connected, and that you figured out the
file system controls (which will actually be improving in the next
revision greatly). At the very bottom of the screen are 4 buttons,
The first is motor control, which does either direct, or vehicle style
control. The second is Sensors, which allows you to see the live
values, and set up sensor logging. The third, as you have discovered
is the file system from which you can run programs and sounds, upload
and download files, and lastly, the fourth is some basic settings.
The motor control tab has two different pages, direct, and vehicle
control. To use direct control, flick the switch for one or more of
the motors, and then set the slider right or left of center for
forward or back. For vehicle control, you can select which two motors
are your vehicles left and right wheels (presently there is no support
for drive motor steering motor style vehicles). Then just drag the
joystick on the screen to move your robot around, you can also turn on
the motion control to move your robot by tilting your iPhone.
