Hi, has anyone made this? or is there any other video tutorials?
Line Following Robot with Basic PD (Proportional-Derivative) control
wired USB keyboard?
I had success with the Indigo installation on Raspbian on the Pi 3 following these instructions:http://wiki.ros.org/indigo/Installation/UbuntuARMthough it didn't install MoveIt successfully, or rViz - which apparently is a bit processor heavy for the Pi anywayI have successfully activated OpenGL on the Pi3 thoughAnd have it networking with some Arduino Chips running sensor inputs and motor outputsI would like it to run a simulated real time model of the robot I'm building, but am thinking I may have to write my own lightweight code for that

Cool will finish it soon but using ROS :)

Yes, this concept could be scaled up to a larger robot. The Max series have been used for this purpose:http://www.zagrosrobotics.com/shop/item.aspx?itemid=521 Here is Max based project:http://www.zagrosrobotics.com/shop/custom.aspx?recid=37In most cases, you could use the same controller, motor driver and sensor (just check the current and voltage ratings)
can this be scaled up to carry something like 70lbs? I know the motors would all bee much larger, but is the tech essentially the same?
Does this work on a Pi3 Model B
What can be used instead of Sparkfun Ardumoto shield??
It sounds like a wiring problem. Double check each wire.What hardware and robot are you using?
hi, it seems like i'm having the same problem. my robot when powered by computer does the calibration sequence then spins constantly to left, when powered my battery it just spins to right in short bursts.
Do i need to enter case G everytime i want to use the program???, how can i put it to work on batteries and not through the computer
dose the black line width matters??? - VENKATA NAGA DINESH KUMARK
What works well is black vinyl electrical tape, which is about 3/4" wide. Very narrow may be problematic. Super wide (nearly as wide as the entire sensor array) will probably be more difficult for smooth tracking with the basic code.The program is also set for a white background with dark tape. You can change the code if you want the opposite. - PrimalEng
What robot are you using?Have you confirmed the qtr sensor is orientated correctly with the headers/wires towards the middle of the bot and sensor located at the front of the bot?When you say Left left left left, do you mean short corrections to the left or just spinning forever to the left?The difference in operation between battery vs. Computer powered, is it a difference in speed only? - PrimalEng
yes, same hardware, same program, same wiring... - VENKATA NAGA DINESH KUMARK
Look in the follow_line() function. There are values of 55 and 200 you will see spread through that function. Try adjusting those or rewrite it to just slow down one wheel while the other runs at full.
Did you figure it out?The first sequence is a calibration. That is the rightleft repeat. After should start following if it is wired correctly and the calibration was successful.Are you using the same hardware as the instructable?
without that I got this error on Raspian-jessiepi@raspberrypi:~/tempsens $ python temp_logger.pyTraceback (most recent call last):File "temp_logger.py", line 6, in <module>import smbusImportError: No module named smbus
Don't forget to install the python-smbus python module:sudo apt-get install python-smbus
