robotic vehicle controling using voice
Abstract : This project was developed in a way that the robot is controlled by voice commands. An android application with a microcontroller is used for required tasks. The connection between the android app and the vehicle is facilitated with Bluetooth technology.
The robot is controlled by buttons on the application or by spoken commands of the user. The movement of the robot is facilitated by the two dc servo motors connected with microcontroller at the receiver side.
The commands from the application is converted in to digital signals by the Bluetooth RF transmitter for an appropriate range (about 100 meters) to the robot. At the receiver end the data gets decoded by the receiver and is fed to the microcontroller which drives the DC motors for the necessary work.
The aim of Voice Controlled Robotic Vehicle is to perform the required task by listening to the commands of the user. A prior preparatory session is needed for the smooth operation the robot by the user. For the same a code is used for giving instruction to the controller.
In this project, we will build a voice-controlled robotic vehicle using Arduino. The robotic vehicle can be controlled wirelessly by voice commands directly from the user.
The robot can move forward, backward, left, right, forward right, forward left, backward left, backward right and can also be stopped. The voice-controlled Arduino robot Vehicle is connected to a Bluetooth module HC-05.
Using an Android app installed on the mobile device, we can give specific voice commands to the robot.
On the receiving end, a Bluetooth transceiver module receives the commands and forwards them to the Arduino, controlling the robot vehicle.
Ambient Noise Sensitivity: Voice-controlled systems can struggle in noisy environments where background sounds may interfere with the recognition of commands. This can lead to misinterpretation or failure to recognize commands accurately.
Limited Command Complexity: Voice commands are often limited to simpler instructions due to natural language processing constraints. Complex or multi-step commands can be challenging to execute accurately.
Accidental Commands: Unintentional voice inputs, such as those triggered by conversations or other noises, can lead to unintended actions by the robotic vehicle. This can be particularly problematic in sensitive or dangerous situations.
Language and Accent Variability: Voice recognition systems may have difficulty understanding different accents, dialects, or languages, limiting their effectiveness for users with diverse speech patterns.
Voice recognition and speech processing is not a new field in robotic industry. Voice recognition system having the ability to work for the disabled people by recognising the commands and work accordingly for the disabled people is the main idea of the project.
Purposed system having the arduino uno voice control system. In which the arduino is connected to L298D motor drier shield which is integrated in between the arduino and the motor driver and Bluetooth module HC05.
Our system consist of an vehicle having two servo motors which are connected to L298D motor proving the signal through the arduino uno by the Bluetooth module voice control app.
Also system is designed for people who are disabled by feet so they can move freely with the vehicle by passing voice commands to the vehicle.
Hands-Free Operation: Voice control allows users to operate the vehicle without needing to physically manipulate controls, which can be especially useful when the user's hands or other limbs are occupied.
Accessibility: Voice commands can make robotic vehicles more accessible to individuals with physical disabilities or impairments who might find traditional controls challenging to use.
Ease of Use: Voice commands can simplify the operation of robotic vehicles by allowing users to speak natural language instructions instead of learning complex control interfaces.
Increased Safety: By enabling hands-free control, voice commands can help users keep their attention on the environment rather than the controls, potentially increasing safety, especially in dynamic or hazardous situations.
