Bluetooth Controlled Robot
A maneuverable mobile robot driven wirelessly from a smartphone over Bluetooth with custom command parsing and directional steering.
About the Project
A wireless differential-drive mobile robot controlled via an Android smartphone over an HC-05 Bluetooth serial link. Features bi-directional motor control with PWM speed throttling, emergency safety stop on signal loss, and instant response steering for navigation across tight corners.
Key Engineering Features
Wireless serial communication pairing via HC-05 / HC-06 Bluetooth module
PWM-based 4-wheel differential drive for smooth acceleration and pivot turning
Automatic fail-safe stop trigger if the Bluetooth connection drops
Custom command packet protocol for directional control and speed modes
