The main purpose of this project is to create a functional prototype of a multilayered system that incorporates aspects of electrical, mechanical, and computer engineering technology. The main objective of the system is to be able to determine whether a light bulb is working or not. The building blocks of this system are a robotic arm that is able to slide along a rail (for added mobility), a conveyor belt, and an electromechanical device that holds and tests light bulbs. Initially, the robot arm picks up a light bulb and places it into the holder which then tests it. A photoresistor is used to detect whether the light bulb turns on; if the bulb lights up, then it works. The robot arm then places the light bulb on the conveyor belt which moves the bulb to the other end of the conveyor belt (sensors are used at either end of the conveyor belt to determine the location of the light bulb). Next, the robot arm slides along its rail into a new position, allowing it to pick up the light bulb which is now at the other end of the conveyor belt. After picking up the light bulb, the robot arm places it in one of two locations depending on if the light bulb works or not. Digital and analog control circuits are used in conjunction with sensors to detect measurands which are then fed into a CPU as data.
