IR sensor is able to detect IR light. As with all sensors, visible light can be detected, but thus one is able to detect InfraRed light which is light above the spectrum of visible light. Coincidentally, Android phones are able to view this light through its camera. Iphones are not able to view such light. Our robot, for testing purposes only, has been customized with a useful state of the art (in my mind. haha), an easy to grab handle. Tall hable is useful so the person, me or my robot partner, does not have to bend down all the way to grab the robot and risk getting fingers caught in the possibly still moving gears. Also useful for mounting a phone as a ash cam , and even is useful to quickly grab the robot in case the collision sensor or programming is not yet working fully properly.

| IR sensor mounted |
The IR sensor for this bot is going to be mounted in front of the bot because that is what is needed to be avoiding obstacles such as the walls. the sensor worked great! The only issue we found was the location in the room. In our test bench we tested the light and we were getting readings of about 500. Our bench area was not greatly lit up. The actual maze competition area, howerve, was greatly lit up by the classrooms lights. The readings in that location was much higher, and hence it was harder to see the IR candle cause of the excess light. Then problem was easily fixed by decreasing the sensitivity of the IR sensor. Since the resistor was already soldered into the sensor, we just simply changed the programming number. Project Success!
