One Year Over!!!!

Oh wow i cant believe one year of college has flown past so quickly..
Its been a year since many things happened.. exams admission councelling tensions.. whew..
And looking back it has been a great year.. Enjoyed it a lot..
Dono wats coming up in the next year.. and the dumb results will also be out soon..
oh boy..
Anyway have been relaxing nicely at home for abt a month.. only eating and sleeping and internet...
Im more clear abt certain things in life.. bit i got more confused about other things..
But I've discovered real good company in college.. wat makes NITT so amazing is the students.
It rocks.. Its a different world inside campus.
Am kinda looking forward to going back.. I think I've lost touch with writing.. my posts are kinda dull dont u think? Maybe I'll get inspiration one of the days.. :-D
anyway catch u later

Making The Line Follower

After successfully making a 'coin picker', we decided to try our hand with a line follower..
We decided to start out with a simple line follower.. using not gates and only two sensors..
For a more detailed look at the theory behind this take a look at this http://www.geocities.com/xjroolz/myrobot.doc or mail me...
Anyway this time around things were not going smooth like before.. we were facing problems..
More than the technical side there was trouble working as a team.. this was the first project we were doing as RMI firstys.. Through this i learned abt the problems associated with the working of any team.. Anyway we had a tough time soldering cos there was sooo much to solder.. And the first board we did dint work! so we tried it on a bread board.. and it worked fine.. It took so much time to get the circuits ready.. we then had to think abt the robots body..
Then we decided to improvise roboray( renamed lofty by one of my friends) We removed the old board.. fixed in the line followers board.. and fixed the sensors out in the front on the electromagnet.. And it was all set to go.. we made some track on a chart paper. And set it up and all ready to go!
We were sure that there will b more problems and we will have to work a lot more.. but then the robot surprised us all by pulling of an extremely smooth 90 degree and continued on the track.
We had seen other bots with 8 sensors and micros and all that but this was much faster and much more smoother compared to those.. credit of that has to be given to the really good high torque dc motors of lofty.
We celebrated the robot with a video session.. here are the videos..



It couldnt take that U turn cos the radius was too short for the robot..



And here we run it in the reverse direction to prove that it can indeed take that turn..
but it became kinda jerky though..


if u cant see the embedded videos try these

So thats it.. nothing much.. I think we are a pretty good team and u may see us soon in local robotics contests.. big hopes(:D)
