ESP32 Gesture-Controlled Robot Car

This project pairs a handheld remote with a separate car unit, both built on ESP32s. The remote reads tilt data from an MPU6050 gyroscope and streams it wirelessly over ESP-NOW to the car unit, which translates that tilt into motor commands. The car itself is a 4WD build — four TT gear motors wired in left/right pairs on a plywood strip chassis — powered by two 18650 Li-ion cells with onboard USB charging and a slide power switch. It runs on ESP-IDF and FreeRTOS rather than the Arduino framework, keeping gesture-sensing and the wireless link running as proper concurrent tasks.
