Every robotic part can be classified as a brain a muscle output or a sense input. The colour sensor is a sensor that senses colours in front of its face. the large angular motor is the muscle's because it's actually the part that powers and makes movements. The distance sensor is, you guessed it, a sensor! This is because it measures how much distance is between the robot and the object. We have tried the distance sensor in one of our codes which worked well and was fun! The 5x5 LED matrix screen is a screen or display, because it is a screen it shows the robot what to do, powering it, and more.
