Abstract
An important step in integrating voice recognition, mobile control, and the Internet of Things (IoT) into robotic systems is the Sonic Bot project. Using Google's voice recognition engine, Sonic Bot, a platform that is small and flexible, can react to user orders sent through an Android application. Firebase is a real-time cloud database that transmits the commands. A NodeMCU microcontroller receives the commands, decodes them, and moves the robot. To identify obstructions in its path, this bot has an ultrasonic sensor. The bot simulates intelligent behavior by doing a U-turn on its own when it detects an obstruction within a predetermined distance in order to prevent collisions. The voltage sensor, which continuously checks the battery level, is another important component. This voltage data is returned to the Android app, where the SpeedView library uses a gauge that resembles a speedometer to graphically depict it. In order to improve user awareness and avoid system shutdown due to power depletion, an LED indicator is also used as part of a low battery warning system.
