Nov 07, 2018· Infrared: Sends out an infrared signal and detects the reflection of the signal bouncing off an object with the front (eyes) of the sensor. Ultrasonic: Sends out highfrequency sound waves that will bounce off an object and measure how long it takes for the sound to reach back to the sensor. These sound waves are too high for a human ear to hear.

The touch sensor is a very useful tool for the job. Using the sensor and a while statement, you can command the robot to move forward until it hits a wall (depressing the touch sensor), stop, and turn. To access a sensor, use the following syntax: SensorValue[sTouch] where sTouch is the name of the sensor. The code would look something like this:
