Sensors



The different sensors that you can include on your robot are the touch sensor, light sensor, and the rotation sensor. The touch sensor can be used to make the robot perform an action after it is pushed in a certain amount of times. So you can tell your robot to keep moving until a touch sensor is hit and then to reverse for two seconds or whatever else you need it to do. A light sensor can be used to make your robot stop when it spots a light color or to perform a function like moving a robot arm when it spots a darker color. Using a rotation sensor you can see the number of rotations it takes your robot to travel a certain distance and you will be able to put this into your program to make your robot's movements more accurate and not put so much work on yourself as if you were using a timer. When you use timers you have to guess the amount of time it takes for your robot to go a certain distance and you have to keep adjusting it but by using the rotation sensor you will almost always get it on the first try or if you are off by a little a couple of more times. As you can see the use of sensors is very beneficial.
