Abstract
With the advent of technology, we are making our lives luxurious. Electricity,
computers, robotics etc. are making our tasks far more easier than we could have
imagined .In our society, it’s a common observation that an ordinary person
intends to make his life luxurious by the utilization of additional facilities whereas,
somewhere, a physically impaired person has a different perspective, he just
wants to make his life ordinary by utilizing advance technology.
Now due to the advancement in the field of Robotics, giving artificial body parts
to physically impaired people has become quite helpful. So our project is designed
to provide a prosthetic robotic hand to the people who have disability so that
they (somehow) would be able to live their life normally. Disabled person can
operate the hand and give commands to garb and release the object through
voice recognition. It also finds application in industry, such as mimicking the
movement of the hand can be performed. At one place human hand with sensors
will move and through wireless signal, robotic hand can be moved on the other
end. Scientists can use this technology for their research in harmful living things.Hostile environment in factories cannot allow humans to work with, so the
mimicking of robotic hand will prove very useful in this field.
Voice recognition module is being trained with user’s voice so that it will not
accept any other voice. Commands to perform specific actions are stored in the
module’s database. User may order the module to perform a specific action by
simply speaking the command. The voice recognition system serves as the
interface between the user and the hand by processing the voice signals into the
required mechanical work. The mechanical work comprises of the movement to
perform certain tasks like grab, release etc. The movement of the fingers is
governed by tactile sensors that sense the requirement of pressure and thus
control the rotation of fingers (an assembly of pulleys, nylon fibbers and motors
managed by microcontroller).
