Long Beach Competition

World I would like to introduce you to SUNNY. Again. He competed Feb. 8, 2014 and I felt did awesome. We had two chances to get a better in the competition and sunny was not able to complete one, but he was really close the first time. He was able to get the the room and find the candle but his positioning was off and when he started the fan he was slightly off and not able to extinguish it. Sunny has a total of three sensors. 

First Sunny has a line sensor in his front side and the line sensor would let him know he was about to enter a room. Second is the Ultrasonic Sonar which is also in the front so that when he approached the candle he will know when to stop on continue advancing. Lastly Sunny has a Flame Sensor! Flame sensor is very cool and different from may other competitors, we placed the sensor on a servo motor and mounted it on the front of Sunny. Flame sensor detects heat and in our code we where able to find the angle from the servo and then have the bot position itself at the angle and proceed getting closer to it. 

Sunny has the smiley face next to it on the Competition score board.

Programing the VEX (Maze)

World please say hello to SUNNY. He was our robot and very loved. He has two moms and even though he was a big head ache for two week his moms still love him. So Sunny has basic frame of the VEX squareBOT. While programing we created commands for sunny to go straight, right turns, left turns, scan, and backup. One of our assignments was to have sunny run a maze right outside of our classroom. We participated the the maze competition but were not satisfied with our outcomes so we kept working on the maze for an extra day. The following video is what we were able to accomplish after the maze competition. 

Ultrasonic Rangefinder & Flame Sensor

After creating the UltraSonic Sensors that we end up using in the competition, we decided to place the sensor in the front of "Sunny". We determined this position of the sensor because in our strategy of finding the candle. We needed a sensor determining how far away the candle is and how to move towards the candle without touching it. 

The UltraSonic Sensor was probably our most reliable and consistent sensor of them all. We had the least issues with it and its values it was putting out. The Ultrasonic Rangefinder measures distances using sound sonar. It sends out a pulse and hears an echo when the pulse bounces back to the bot.  

This is our flame sensor. I personally made this sensor and initially it was perfect and collected great data. We noticed as we started using Sunny that the Robot needed to endure tough handling. Unfortunately the flame sensor was one of our greatest issues. Since our flame sensor was nailed and taped on a servo it endure many movements. Ultimately our sensor worked properly with our code but or code need some modifications to get the BOT back to sensing moving towards and extinguishing.
