How It Works

The Gesture Controlled Robot system is divided into two primary sections: a gesture-transmitting glove or handheld unit and a mobile robot receiver. On the control end, an Arduino Nano interfaces with an MPU6050 accelerometer and gyroscope sensor via the I2C protocol (using the Wire.h and MPU6050.h libraries) to track the spatial orientation and tilt of the user's hand. These motion coordinates are processed by the microcontroller and wirelessly transmitted via an NRF24L01 transceiver module utilizing the SPI protocol and the RF24.h library. On the robot side, a matching NRF24L01 module receives the wireless movement commands. An Arduino Uno processes these incoming instructions and sends appropriate control signals to an L298N Motor Driver Module. The L298N acts as an intermediary power amplifier, regulating current from the 7.4V Li-ion or 9V battery to drive the DC motors on the 2WD Acrylic Chassis kit. By tilting your hand forward, backward, left, or right, the MPU6050 captures these changes, allowing the robot to mimic the directional commands in real time.

Frequently Asked Questions

Can I use an Arduino Uno for both the transmitter and the receiver?

Yes, you can use any combination of Arduino Uno and Arduino Nano boards for the project, as long as one is dedicated to the transmitting glove and the other is mounted on the robot chassis.

Why do I need a separate motor driver like the L298N instead of powering the motors directly from the Arduino?

DC motors require more current than an Arduino digital pin can safely supply and often run at a higher voltage, so the L298N motor driver is necessary to safely switch and supply power from the battery to the motors.

How do the transmitter and receiver modules communicate with each other?

They communicate wirelessly using the NRF24L01 transceiver modules operating on radio frequency, managed in software through the SPI bus and the RF24 library.
