This research proposed a wireless control system for a follow-me robot as an alternative to visual tracking, which has a high computational load. The purpose of this research was to design and build a four-wheel-drive robot using an ESP32 as the main controller and three ESP32-C3 modules. The applied methodology was based on the comparison of signal strength values. One module acted as a target transmitter, while two modules on the robot's sides functioned to receive the transmission and send data directly to the main controller via the ESP-NOW communication protocol. The test results showed that the robot could respond and follow the target's direction based on the difference in signal strength received by the left and right modules. Furthermore, the standby mode on the robot functioned well when the target transmitter was turned off. In conclusion, this wireless communication architecture could operate well in guiding the robot's movement while minimizing the use of sensor cables.

Abstrak
Penelitian ini mengusulkan sistem kendali nirkabel pada robot pengikut sebagai alternatif dari pelacakan visual yang memiliki beban komputasi tinggi. Tujuan riset ini adalah merancang bangun robot berpenggerak empat roda menggunakan pengontrol utama ESP32 dan tiga modul ESP32-C3. Metodologi yang diterapkan didasarkan pada perbandingan nilai kekuatan sinyal. Satu modul bertindak sebagai pemancar sasaran, sementara dua modul di sisi robot berfungsi menerima pancaran dan mengirimkan data secara langsung ke pengontrol utama melalui protokol komunikasi ESP-NOW. Hasil pengujian menunjukkan bahwa robot dapat merespons dan mengikuti arah sasaran berdasarkan perbedaan kekuatan sinyal yang diterima oleh modul kiri dan kanan. Selain itu, mode siaga pada robot berfungsi dengan baik saat pemancar sasaran dimatikan. Kesimpulannya, arsitektur komunikasi nirkabel ini dapat beroperasi dengan baik dalam memandu pergerakan robot sekaligus meminimalkan penggunaan kabel pada sensor.
