Design and Development of Bot using Theo Jansen Mechanism

Abstract

Unlike human being’s bots never get tired, they can be replaced or be swapped and can be used for multiple purposes. Legged robots can be utilized for space missions on extra-terrestrial planets and in risky places. Low power consumption and weight are further advantages of walking robots, so it is important to use the minimum number of actuators. The objective is to design and fabrication of prototype of the Theo-Jansen four leg strolling robot. The essential Theo Jansen device is a 13-bar framework that strolls when a crank is rotated. The central 'crank' link moves in circles as it is actuated by a rotary actuator. All other links and pin joints are unactuated and will move because of the motion imparted by the crank. It may be utilized as a military robot by a few modifications on it such as Guns, Radar, GPS, etc. Where military rangers cannot go, it may be utilized as a surveillance bot. Developed bot is radio frequency controlled and effectively designed for low speed and based on requirement speed can be increased by using higher speed motor.
