When we developed the Zebro Light robot featuring the (original) Beaglebone, we frequently had to go out for field tests. Inside the university building, we could use WiFi to program and debug the robot, but this was impractical (and occasionally dangerous) as the robot walked outside of the WiFi range.
Open Electrons has come up with a solution: the BBConsole. BBConsole gives you wireless access to the console using Bluetooth. The device fits in the space between the BBB headers, so you can continue using capes without conflict. You’ll want to hurry, though. The Indiegogo campaign has only just over a week left.
They’ve developed several apps to control the BeagleBone Black from supported phones. Open Electrons told me that the console will also work with a PC or Laptop if you have a Bluetooth 4.0 USB dongle. (Handy if you need to hit CTRL+C really quickly when the motors on your robot start to move unexpectedly!)
