| dc.description.abstract | Robotics plays a vital role in modern engineering, particularly in applications involving
automation, material handling, and operations in complex environments. This project presents the
design and development of a Stair Climber Robot with Gripper, capable of navigating staircases
and uneven surfaces while handling objects. The robot is powered by a 12V DC gear motor and
three 3.7V batteries, with an Arduino Nano serving as the central control unit. Ultrasonic sensors
detect stairs and guide the robot’s movement, while an MG995 servo motor adjusts the front wheel
for smooth ascent or descent. A force sensor triggers the gripping mechanism, controlled by SG90
servo motors, enabling secure object handling. Wireless control is achieved using a NodeMCU
module integrated with the Blynk IoT platform, and motor direction is managed via a relay
module. Mechanically, the robot employs a three-wheel series configuration with a belt-driven
system for coordinated movement and torque transmission. The system effectively combines
mechanical design, sensor integration, embedded systems, and IoT-based control, making it
suitable for applications in material transport, hazardous environments, and research in
autonomous robotic mobility. | en_US |
