The Six-Legged Spider Bot Using Klann Mechanism (RF Controlled) is a mobile robotic platform designed to imitate the walking movement of a spider using a mechanical linkage known as the Klann mechanism. The robot is controlled wirelessly through an RF transmitter and RF receiver, allowing the user to move the robot remotely without physical connections. A microcontroller receives the RF commands and controls a DC motor through a motor driver circuit. The rotational motion of the motor is converted into a legged walking motion by the Klann linkage, enabling the robot to move over uneven surfaces more effectively than conventional wheeled robots. The system is powered by a Li-Po battery, making it portable and suitable for outdoor operation. A crystal oscillator provides accurate timing for the microcontroller, while a reset button ensures reliable operation and LED indicators display the system status. The six-legged structure provides better stability and balance during movement. The proposed robot can be used for surveillance, inspection, search-and-rescue support, and educational robotics applications where terrain adaptability is important.
