Design of a Multi Sensor-Based Low-Cost

Robotics industry is rapidly growing, and it has grown spectacularly in the past century. Due to their complex components and complicated underlying physics, people have chosen to circumvent understanding the phenomena within the actions that a robot makes, and actually study robotics from a technical point of view rather than using an engineering approach. In this project, a group of students designed and built a robot that is capable of executing two to three different gestures. The team ultimately designed and built a robot miniature car that has the ability to detect obstacles on its way, and is capable of following a black line path, along with other sound and light sensitive gestures. The robot was collected and gathered using a robotic components kit, and the designed robot car was constructed using low budget mechanical tools and equipment. Mainly, two servomotors were used along with other mechanical components and an Arduino control board. The robot was programmed using Arduino open-source software and it was intended to make the robot do the different gestures. The testing procedure for the robot car was successful as the team hypothesized; the robot was able to successfully operate as programmed and performed all the intended gestures. This paper will describe how the robot was built using only $250 resource and how it was programmed and demonstrated in some detail, so that other students can follow the design and controls of the robot.
