the powerpoint day

on tuesday february 15th we all just sat in class and enjoyed a very enthusiastic talk by professor mason about presentation so now we have to duplicate what he did and present our vex bot to the class in 10 to 15 minutes
may god help us because i havent even finished half of it because i was so much behind on all my blog entries that im doing the last of them now which is exactly 50 minutes to class :D

This is not one of the 18 days blog entries

This is not one of the 18 days blog entries this is kind of an explanatory blog to say why my last few entries does not have videos or pictures
i tried sending files from my iphone via email but for some reason it keeps failing
i promise to upload the images and movies  as soon as i fix the issue

Vex Competition Day

so finally on the highly anticipated competition day i arrived at the college campus at 10 and started wandering around until my teammate showed up and we started doing some last minute programing which in my idea only made the bot worse anyhow on our turn it was an embarrassment and a failure or maybe not since the only groups who actually had a bot up to bar were the Andy's group and also brian and Mitchels group because they all have had prior experience in the field because of being part of the robotic club but still that is not the only reason i found Brian and Mitchels Bot design very interesting and i know for a fact that specially Brian is very creative and dedicated and as for andy he is a hard worker and dedicated person who wont leave his goal until he reaches it.  as for our robot if i am being honest both me and ben coming late class hurt us a little bit and also my lack of experience in programing.

last tuesday before the vex competition

on last tuesday before the vex competition i mostly worked on programing the infrared sensor and the line sensors.  after doing so all day i combined the code for both and tested it on the bot and heres the result

note that at this point only one of my line sensors was working the other one i later realized at this time shorted because the soldering joints on the back of the sensor had torn the tape that i had put on it apart and were touching the metal parts of the bot and thats why at the end of the film our bot gets stuck on the line

More programing for Sonar

so on thursday after fixing the issue with the sonar not reading any value i practiced with the sonar system and i realized that the range for the sensor was not very far so when the object was too far the sensor would read the value of -1 which just made the programing harder since i had to tell the bot to also consider this case as the object being too far so go forward.
anyhow after me complaining a lot about the sonar sensor and how it is ineffective professor mason probably got tired and gave our group an infrared sensor which works 10 times better at least in my idea and that also proved that nagging could actually work. :D

more work on Vex Bot

so after finishing my line sensor on tuesday we decided to make another line sensor for the bot and it took me about an hour and half to do so this time around and after finishing up the sensor i started programing and instaling the sonar sensor on our bot but me and also other people faced some difficulty getting any values from the sonar into the programming anyways because of lack of time on that day professor mason suggested to continue working on the programing the day after.

line Sensor

On first tuesday of february while Ben was working on the color sensor all day i was struggling with the line sensor but eventually i mastered it and you can see the result below

the purpose of the line sensor as its mentioned in the name is to sense the line and tell the bot to turn and does not pass the line.
