Low-Cost Robotic Arm for differently abled using Voice Recognition

Vast number of control researches and numerous control applications were displayed amid the most recent years, focused on control of robotic arms. A robotic arm is a kind of mechanical arm, ordinarily programmable, which have similar abilities to a human arm. Building a mechanical arm is certainly not another idea, yet in the meantime, the structure and the determination can fluctuate from various plans. We developed a working prototype of a voice-controlled robotic arm for physically differently abled people. The main aim of the project is to develop a low-cost robot hand that is light and strong. Robotics is an interesting area of research in the field of Engineering. Our project is a voice-controlled robot which does some predefined actions based on the commands we give. We are giving the input speech through the Android phone. The Android operating system widely used in mobile phones, digital cameras are user-friendly and can be controlled by everyone. The Android phone and robotic arm are associated with Bluetooth module. The hand movements are done using circuitry of servo motors which placed and aligned at specific rotations and positions. The movement control is done by a microcontroller. The controller receives a voice command from the smartphone and the nature of the grab will be depending on the voice commands received.
