The ESP32 microcontroller receives commands through wifi from the app

It then generates PWM signals to control the ESCs’ throttle inputs

adjustes PWM duty cycles, the ESP32 regulates motor speed and fan suction dynamically

IR sensors detect surface transitions, their signals feed into the ESP32, which modifies PWM output in real time, auto or by command, suction fans momentarily increase power during tricky transitions, stablizes the robot, the app provides a user interface for manual control,

commands are sent to the ESP32, translates these into precise PWM signals for the ESCs synchronizes motor behavior with sensor input

the main focus is on drone motors, ESCs, IR sensors, and the climbing mechanism

The robot uses two ducted fans for suction and eight motors for movement.

IR sensors adjust fan speed during surface transitions.

ESCs convert battery DC to three phase AC for drone motors.

Result: a stable wall climbing robot like a quadcopter.

what fascinates me in this project is the AC 3 phase…
