To fit the electronics, a box was attached to the right leg of the original model. The box contains receptacles for the boost converter, Arduino nano clone and stepper motor driver board used. The following electronic components were used: Stepper motor 28BYJ-48 Stepper motor driver board with ULN2003 https://www.amazon.de/gp/product/B07VGV1XFT/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1 Arduino nano clone from Elegoo https://www.amazon.de/gp/product/B0713ZRJLC/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 A simple boost converter is used to power the motor with 7.2V, while using a 5V USB cable as input. The Arduino works fine with this input, but the motor runs slower and has less torque at 5V.
