Robots and drones

Difficult to build, but just as rewarding

ESP32 systems are designed for robotics projects, and considering their budget-friendly price, you can grab a handful of these microcontrollers when designing your next robot or drone. As for its utility, the ESP32 can drive motors and accept positional input from sensors.

Meanwhile, the Raspberry Pi can function as the control center. With something as powerful as the Raspberry Pi 5, you can even design a fully autonomous drone that can instantaneously process the readings from the ESP32’s sensors and send control signals after running path-finding algorithms.
