Our replica of the R2D2 robot from the Star Wars film series was made in a reduced size, with the aim of not only being visually recognizable, but also functional. We wanted to create an interactive model that can move and communicate with users, which gives it an extra dose of fun and realism.
The robot is powered by a mobile application via the HC-05 Bluetooth module. It can move forward, backward and turn in both directions. All functional modules – motors, sensors and a speaker – are connected to the central control system, the Arduino Uno board. Power is provided by batteries placed in special housings inside the robot.
An IR sensor is mounted in the robot’s head through a carefully drilled hole, and its function is to recognize movements. When the user waves in front of the robot, a pre-recorded audio recording is activated: “Hello, my name is R2D2. Nice to meet you!”
Functionality programming, including movements and sensor control, was performed in the Arduino IDE environment. This project is a combination of electronics, mechanics and creative design, perfectly suited for educational presentations and exhibitions of technology and robotics.
