Abstract
Regardless of how prevalent wheeled robots are in the industry, they have a significant disadvantage when traversing abrupt short elevation changes, such as
stairs or rough terrain. Animal and human legs inspire the design of a walking automaton capable of resolving this issue. Theo Jansen's mechanism, which can
transform rotational movement into a walking pattern, is one of the most effective leg mechanisms. Theo Jansen's mechanism will be applied to the robot in order to attain robot stability. This project's objective is to design an autonomous multi legged robot that can move in a straight line and avoid obstacles for a variety of applications. The robot will be equipped with Gyroscope Sensor and Ultrasonic Sensor to achieve the goal of this project. The gyroscope sensor will be used to maintain the path of the robot to move in a straight line, while ultrasonic sensor is required to detect the obstacles and finding a clear path for the robot. The robot's mechanical structure will be designed to support the leg mechanism and sensors and guarantee walking stability and balance. Additionally, to achieve optimal performance and flexibility, the leg mechanism will incorporate 3D printed parts, enabling rapid prototyping and customization during the design iterations. The software that will be used to design and configure the robot is Arduino IDE and SolidWorks. The fabricated robot able to avoid obstacles and moving in a straight
line with the help of autonomous function. The robot average speed is 0.40 m/s.
