Prosthetic Hand: Basic Functional Design

Prosthetic Hand Project (July 2022 – Dec 2022): Developed a prosthetic hand to assist individuals with physical disabilities, focusing on integrating microcontrollers, EMG muscle sensors, and servo motors to replicate human hand movements. The project involved using an Arduino Nano, EMG Muscle Sensor V3.0, five TowerPro MG996R servo motors, and a 3D-printed hand. Through programming in Embedded C on the Arduino IDE, I learned to interpret EMG signals for real-time motion control, gaining hands-on experience in sensor interfacing, actuator control, and biomedical signal integration in robotics.

Quadruped Robot Project (July 2023 – May 2023): Designed and built a four-legged quadruped robot, implementing both forward and inverse kinematics for movement and stability. The robot was assembled using 3D-printed parts, twelve servo motors (three per leg), and an Arduino Nano, with motion planning algorithms developed in Python. This project deepened my understanding of robotic kinematics, workspace analysis, and trajectory generation, while also exploring future enhancements such as IMU-based dynamic balance and adaptive machine learning for locomotion.

Dustbin Collector Vehicle (Jan 2023 – April 2023): Created a four-wheeled rover equipped with a two-axis robotic manipulator and a magnetic docking system for collecting and dumping dustbins. The system used an Arduino Uno, three servo motors for the manipulator, four DC motors for mobility, and joystick modules for intuitive control. This project enhanced my skills in real-time analog input processing, integration of mobile and manipulator systems, and efficient microcontroller I/O management, resulting in a semi-autonomous mobile manipulator capable of real-world tasks.
