Bot Commander r1 Released

I just published Bot Commander, the code for my Lego NXT rover. There's a lot left to be done, but release early and often, right?

Currently it provides a UI for controlling the direction and speed of all three motor ports on the NXT brick. You can link motors together to adjust their speed in unison. In addition, you can enable "Tilt Control" for a steering-wheel-type experience. To use tilt control:
  • Hook up motor A and B to be the left and right wheels of your vehicle.
  • Hold the phone sideways (i.e. landscape).
  • Tilt the phone forward and backward to drive forward and backward.
  • Turn the phone right and left (like a steering wheel) to steer right and left.
As you tilt the phone, you'll see the UI update the slider controls for the speed of motors A and B.

I plan to expand the UI to provide a lot more than just motor control. Before that, though, I'll push a JAR to make it easy to integrate control of Lego NXT robots into your own Android project. The code is based on iCommand, which already supports a lot (if not all) NXT sensors and such, both official and after market.

Expect updates as I continue working on my rover. Scan the QR code below to install.

  1. How do you get the phone to connect to the NXT? Does this require installing a different firmware on the NXT? Thanks.

  2. It connects via Bluetooth. The original NXT firmware is all that's necessary.
