This project waited on the shelf for so long, that I decided to scrap it and rebuild into #Hexapod Henk MkII. Go there for the latest news on the project. This project is kept for archive.
The legs are arranged in a circle, every 60°. The alternative was to have them in two rows, but they seemed to be too close together that way.
The power switch has a couple of 47kΩ resistors added to it, which form a voltage divider, connected to an analog pin. This way I can tell the battery voltage, and monitor it. Since the analog pin also doubles as DAC pin, I had to remove the speaker. It's a bit of a shame, but it was too quiet anyways. I might add a proper audio board in the future, if really needed (or monitor the voltage differently).
