Sensors provide a safeguard against this, allowing robots to, for example, disable a motor if a mechanism is against a hard-stop. Sensors 14 Encoders 14 Ultrasonic Sensor 14 Switches 14. Making use of sensors is an absolutely crucial skill for on-field success while most FRC games do have tasks that can be accomplished by a “blind” robot, the best robots rely heavily on sensors to accomplish game tasks as quickly and reliably as possible.Īdditionally, sensors can be extremely important for robot safety - many robot mechanisms are capable of breaking themselves if used incorrectly. Devices that provide feedback to the robot on the state of its environment are called “sensors.” There are a large variety of sensors available to FRC® teams, for measuring everything from on-field positioning to robot orientation to motor/mechanism positioning. In order to be effective, it is often vital for robots to be able to gather information about their surroundings. I am using two ultrasonic sensors that provide real distance information to the next wall, door or object, and when someone crosses between that space, the sensors will detect it, and according to the order in the sensors readings, it will count as a person entering or leaving the room.
