Repository for hosting a hobbyst spider robot project.
The project is built around a Raspberry Pi Pico development board.
It's also using Cytron Maker Drive DC motor control board, HC-SR04 ultrasonic distance sensor and a bidirectional logic level convertion board. The movement and is based on DC motors and mechanisms from two DFRobot Spider Robot kits. The power supply is a cheap 3,7 V LiPol battery - currently 2200 mAh.
I'm also using a TP4056 LiPol charger.
For the connections I'm using some cheap chinese cables, two medium sized solderless breadboards and four electrical quick couplers.
The robot is programmed in MicroPython and uses a HC-SR04 driver library created by Roberto Sánchez (https://github.com/rsc1975/micropython-hcsr04).
Feel free to use this idea, improve it and publish your modified versions (let me know if you do it), according do the license specified on githb and in the main.py source code file.
Bellow you can find links to the parts listed above (on their producers or distrubutors web pages).

The connection schematics picture was created in Fritzing (https://fritzing.org/) - great peace of software for hobbysts. All of the coding and software deployment was made using Visual Studio Code (https://code.visualstudio.com/) with the Pico-Go extension (http://pico-go.net/).
