Modified Transcript: Basically what a sensor does is takes a physical property and transfers it to an electrical signal. An example of this is a temperature sensor takes the physical property "temperature" and converts it into a signal that the robot can interpret. Sensors are important to robotics for two main reasons. First of all, they allow the robot to become more autonomous because it can perceive its own environment and through programming it can make decisions based on what it perceives. I Sensors are also important to robotics for remote operation, because they give the remote users the ability to "see" what is going on and make decisions about what the robot should do next.
