Line following robot based on the dsPIC33
Exapod is building a line following robot based on the dsPIC33 and stuff he won from SparkFun‘s giveaways. Watch the little robot race through Monza in a video below.
i’m planning of building a robot with a dspic33fj128mc804 and two encoders for implement some dead reckoning algorithms so for learn something on the dspics i build a line-follower, it uses 6 analog sensors that are read with the auto-scan capability of the chip, the pwm is 12 bit and the control loop runs at almost 30 kHz (it only calculates the line position and the do a very simple PD routine that use fixed point math).

Errr, why is it going around Monza the wrong way?
Hi, iam student can you share with us ur code? thanks
Sorry i just saw this comment. Can you send me your email adress via a PM on the forum?
hello I have a similar project for my studies can you provide me a documentation about your robot ?
I mean source codes and parts used for vidéo processing !!! thank you
Like i said before if you send me a PM on the forum with your email i will send you everything that i have on that robot.
Keep in mind that the source code is very strange because my programming skills are what they are :).
What do you mean by video processing?
I thought that the robot contains a camera to detect the black line it’s kinda what I’m willing to do
thank you very much I’m sending you my email
PS: I will try to modify the source code so I can add the video processing module
This robot uses 6 infrared sensors to “read” the line position but in particular for my program anything that outputs the line position in terms of a number form 1000 to 6000 is ok.
