In his latest regular column for Robot Mag, Carl Owen of DSP Robotics controls the Buggy from an Xbox controller via FlowStone.

Since clicker 2 for STM32 uses the same MCU as FlowPaw does, it took a few tweaks to the Buggy firmware to make it work with FlowStone, the graphical programming language. It’s probably the easiest way to prototype with the Buggy.

In this case, Carl simply connected the Buggy with an Xbox controller using one of the FlowStone modules. He made some additional connections to ensure that the brake lights come on when the four wheeler comes to a stop.

That’s just a starting point of course. A total of 12 click boards are supported in FlowStone. Adding functionalities is simply a matter of dragging and dropping the appropriate FlowStone modules, and thinking through all the interactions between them.

You could enhance the Buggy with a parking sensor/obstacle avoider using Proximity click, program it to follow a predefined route with GPS click, or spell out messages with 8×8 click, to name a few examples Carl covers.

Just beware that the FlowStone-compatible firmware tends to attract paws of all sorts. Jessica the cat, shown here, uses the Buggy as a pillow, a low-tech, but nevertheless useful application.

Yours sincerely,
