'Building a Raspberry Pi + ESP32 Drone: My First Steps Into Robotics' robotics drones
Hello, everyone! My name is Anton. And I want to share the story of my first steps into robotics and particularly about my Raspberry Pi + ESP32 drone. At the beginning of the story I was working as a web developer , had some C++ knowledge, as for electronics skills — I could solder ripped headphone wires. The problem was that being a web developer I started to feel dissatisfied because what I do doesn’t affect the physical world in any meaningful way.
Instead, I had to improvise and use shoelaces and my own hands which sometimes led to minor but unpleasant injuries. And it kinda worked except for the case when propellers were working, creating turbulence which interfered with ultrasonic sensor readings at heights above 40cm. When I finally found it out I had to replace the ultrasonic sensor with a laser one.
I didn’t consider that pitch turns into roll and vice versa if the inclined drone is rotated around its local z-axis. So I made this PCB on the fourth attempt. The hardest part was actually applying the solder mask. What this PCB does is that it interconnects sensors, ESP32, and Raspberry Pi and delivers appropriate voltage to different parts.
