Voice Controlled Robotic Vehicle
Voice Controlled Robotic Vehicle report
Abstract: Speech recognition is a technologywhere the system understands the words given through speech. Voice Controlled Robot (VCR) is a mobile robot whose movement can be controlled by the commander by giving specific voice commands. The speech is received by a microphone and processed by the voice module. When a command for the robot is recognized, then voice module sends a command message to the robotís microcontroller. The microcontroller analysesthe message and takes appropriate actions. The goal of this project is to introduce hearing AI sensor and also the speech recognition to the mobile robot such that it is capable to interact with human through Spoken Natural Language (NL). Two type of approach we have chosen for Voice User Interface (VUI) implementation -using a Hardware and SoftwareSR system, and this system uses an android application to recognize human voice and is converted to text; text is further processed and used to control robotic movements.Speech is an ideal method for robotic control and communication. The main objective is to minimize the cost involving in the project and power consumption satisfying the need of the day at the same time. Our goal extends in involving our proposal to provide efficient, accessibility and manipulation of everyday objects.Now dayís smart phones arebecoming more powerful with reinforced processors, larger storage capacities, richer entertainment function and more communication method. Bluetooth is mainly used for data exchange; add new features to smart phones.shows its advantage by integrating with smart phones. The person use digital technology at home or office, and has transfer traditional wired digital devices into wireless devices. In recent years an open source platform Android has been widely used in smart phones . Android has complete software package consisting of an operating system, middleware layer and core applications. Different from other existing platforms like IOS, it comes with software kits (SDK), which provides essential tools and applications. Using a smart phone as a brain of robot is already an active research field with several open opportunities and promising possibilities. This project presents a review of current robots controlled by mobile phone and a closed loop control systems using audio channels of mobile devices, such as phones and tablet computers. In our work we move the robot (forward, backward, left right) by the android application.
