When is a box not just a box? When it has six servos attached to the bottom that are hooked up to a circuit board — capable of controlling 16 R/C servos or speed controls. It’s powered by a 7.2V R/C battery. Overall, “The Walking Box” cost Ryan just shy of $100 (excluding board material) to complete. Video clip after the jump.
From the article: “I created the schematic using EAGLE and used an LPKF Circuit board mill to cut the traces and drill the holes. I soldered the vias and components by hand and program the chip via Quickbug bootloader over a serial connection to my PC. The code was written in C and compiled with the CCS compiler available on lab machines here at Penn State Behrend.”
