What is smart wheelchair?

A smart wheelchair is a power wheelchair (PWC) that collects information on driver behavior and interaction with their environment. This is done through the use of sensors and/or cameras positioned to provide feedback on a driver’s ability to control the device and navigate their environment safely.

How does voice control robot work?

The voice command is converted to text by an app of the android phone and sends necessary data to the microcontroller for controlling robot movement. After receiving the data the robot responses according to the command by performing proper movement to the proper direction according to the voice command.

When were smart wheelchairs invented?

To accommodate this population, researchers have used technologies originally developed for mobile robots to create “smart wheelchairs.” Smart wheelchairs have been the subject of research since the early 1980s and have been developed on four continents.

How much is a smart wheelchair?

It is possible to use recycled parts and still have satisfactory performance. Hopefully, it should be possible to construct the smart electric wheelchair within $260 where commercial power wheelchair with similar facilities and appearance will cost more than $2000.

How do you make a voice control robot?

How to Make Voice Controlled Robot

1. Step 1: Gather the All Parts and Tools. 1 x Arduino Uno. 1 x HC-05 bluetooth module.
2. Step 2: Connections of Parts. Connect 4 jumper wires to HC-05 bluetooth module. Plug in Tx pin of bluetooth module to Rx pin of arduino.
3. Step 3: Programming the Code. arduino code given in below link –

What is voice controlled robotic vehicle?

Voice controlled robotic system is controlled through voice commands via android device. The inte- gration of control unit with Bluetooth device is achieved using a Bluetooth module to capture and read the voice commands.

Does Arduino have voice recognition?

Arduino Code for Arduino Voice Recognition Here some changes have been made to control LED with the voice commands. After making the changes, upload the code into your Arduino. Open the serial monitor at 115200 baud. This is how you can build speech recognition using Arduino and give commands to operate the devices.

How does a mind controlled wheelchair work?

A mind-controlled wheelchair functions using a brain–computer interface: an electroencephalogram (EEG) worn on the user’s forehead detects neural impulses that reach the scalp allowing the micro-controller on board to detect the user’s thought process, interpret it, and control the wheelchair’s movement.

What are the benefits of a wheelchair?

In addition to providing mobility, an appropriate wheelchair benefits the physical health and quality of life of the users by helping in reducing common problems such as pressure sores, progression of deformities and improve respiration and digestion.

What is the most expensive wheelchair?

The World’s Most Expensive Wheelchair? — Stephen Hawking’s 1988 power wheelchair sold at auction last week for approximately $385,000 USD. Projected to sell for around $20,000 by the Christie’s auction house, the iconic red wheelchair beat all expectations.

How to control direction of wheelchair with voice control using Arduino?

This project involves voice recognition module which will recognize the voice of the user and process the command of the user and send it to the Arduino. The user has to save the different voice commands in voice recognition module before use it to control the direction of the wheelchair. Arduino is a microcontroller based board which accepts data.

What is a voice controlled wheelchair?

A voice controlled wheelchair makes it easy for physically disabled person who cannot control their movements of hands. The powered wheel chair depends on motors for locomotion and voice recognition for command.

How does a powered wheel chair work with Arduino?

The powered wheel chair depends on motors for locomotion and voice recognition for command. The circuit comprises of an Arduino, HM2007 Voice recognition module and Motors. The voice recognition module recognizes the command by the user and provides the corresponding coded data stored in the memory to Arduino Microcontroller.

How does a smart wheelchair work?

Sensor will be mounted on a smart wheelchair. A single battery will power the sensors, Arduino, voice recognition module and driving two DC motors. Ultrasonic sensors are also used to provide extra protection against obstacles at close range.
