TrongsWallFollowingTrong's Wall FollowingSummary, Problems, and DebuggingFor lab 5, I was responsible for providing a code that follows walls using distance sensors. With these distance sensors, which are external sensors, I am able to tell how far I am from a wall without using the Create’s demo for wall following. To begin, I made a flow chart that would plan out the code that the Create will be following. I did this because I didn’t have a flowchart on the last lab report, and it cost me dearly in terms of getting a good grade. Since I have a flowchart, I have a more structured idea of how to go about completing my code. After completing my flowchart, I first tried to break the code into smaller parts in order to place together when I finished all of the different pieces. This was a smart and good step for me because I am starting with a logic to go by. Some of my problems included small technical problems such as spelling problems within the code. Another problem was when I was soldering the wires to make them longer. I did not solder the wires well enough and it caused the sensors to not work at all. Some debugging tools I used included using the cricket display. By using the cricket display, I was able to see how far the Create traveled as it is running its code. This was an efficient and productive way of debugging because it is exact and I don’t have to keep track of anything. Another way of debugging that I tried was by using the LEDs to tell me what stage the Create was in or what part of the code it is performing Lessons LearnedSome things I learned included soldering. When soldering, I should be more careful and make sure that I use the wire holders to hold the wires for me when I solder. When I was soldering, I had others hold the wires for me and I later learned that it was a hazard to the person that was holding the wires and it could have caused harm to both me and my assistant. Another lesson was to mind what things I am typing when writing my code. Often at times, I would type in code and misspell words that would make the code not make sense. So by proofreading after writing code, I am able to track down little mistakes that would harm my progress. Trong's Wall Following Picture Δ |
