VEX-276-2155 VEX Robotics Ultrasonic Range Finder Kit <p> <font color="00ff66" size="2" face="Arial, Helvetica, sans-serif">An ultrasonic range finder sensor enables a robot to detect obstacles in its path by utilizing the propagation of high-frequency sound waves. The sensor emits a 40kHz sound wave, which bounces off a reflective surface and returns to the sensor. Then, using the amount of time it takes for the wave to return to the sensor, the distance to the object can be computed. A Programming Kit is needed to change the program
in the Vex Controller.</font></p>
<p><font color="00ff66" size="2" face="Arial, Helvetica, sans-serif">The sensor can be used to determine distances to objects. It can be used as a tool to determine if any objects are in the robot's path at all. To increase the sensing range, the sensor can be mounted to a servo to allow it to rotate.</font></p>
