Nxt touch sensor how does it work

You can also use the Light Sensor to make a line-following robot or a robot that can sort things by color. The Ultrasonic Sensor enables your robot to see and detect objects. You can also use it to make your robot avoid obstacles, sense and measure distance, and detect movement. The Ultrasonic Sensor measures distance in centimeters and in inches. The Ultrasonic Sensor uses the same scientific principle as bats: it measures distance by calculating the time it takes for a sound wave to hit an object and return — just like an echo.

Large sized objects with hard surfaces return the best readings. Objects made of soft fabric or that are curved [like a ball] or are very thin or small can be difficult for the sensor to detect. Each motor has a built-in Rotation Sensor. One rotation is equal to degrees, so if you set a motor to turn degrees, its output shaft will make half a turn. Good idea. If you or anyone has those details and would like to write a post about the EV3 sensors, please let me know.

Select the desired combination of Touch Sensor inputs that will be combined to create the overall logic output. In the default state, all four Touch Sensors must be triggered to create an overall true output. If a Touch Sensor input is not needed to contribute toward the overall logic output, then Ignore should be selected. If a Touch Sensor input is needed but in the untriggered state to contribute toward the overall logic output, then False should be selected.

Up to four Touch Sensors can be wired to the connectors labeled 1 — 4. Other Programming Enviornments. Additional information Weight. Related products. Accessories , HiTechnic. Open Mobile Search. Off-Canvas Navigation Menu Toggle.
