I have been following your project closely. Thank you so much for sharing with us the two years of your hard work. Would you please let me know where did you buy the aluminum plate that you are using as your chassis?
Hi John, thank you for following my project. I used a scrap piece from our ceiling renovation that i sawed and bent according to my early robot design CAD. If you have a local metal shop I would go there and ask if the have scrap pieces that you can buy.
Hi, you are right. At one point it passes the perimeter wire and then gets back in. I think I need to add software filtering of the sensor signal as the brushed cutter motor adds alot of noise which adds both false positive and false negative reading of the pulse.
Thank you, yes you can use the same motor without decoders and the have a lower price. You can find on Amazon if you use the link and look for alternatives. You will the need to remove the code that uses the decoders to set the motor speed.
@Robert Malmstrom just to confirm if it is this part only or anything else? // Is the robot going forward? if (m iDirection == ciForward) { forward (0); ReadMotorSensorSpeed (); }
The schematics for the Perimeter sensor amplifiers and the Perimeter Station are now available here: robertmalmstrom5.wixsite.com/robelibob/electronics

Awesome !
Thank you! I will soon put up more information about the perimeter wire system on the robot webpage. Link is in this video description.
@@robertmalmstrom942 Great ! Looking forward to see more of this !
@@PhG1961 Philip, I have now added schematics and updated the source code on the robot website: robertmalmstrom5.wixsite.com/robelibob
@@robertmalmstrom942 Really cool !!
Was the drawing of the perimeter wire wrong, or did it go far outside the perimeter?

Hey. It's amazing project. Can i use same motors but without hall sensor? Do i need update code?

@Robert Malmstrom , thank you. Can you please advise the line numbers that i need to delete?
Hi, in the void loop() function you should remove or comment out this function call:
ReadMotorSensorSpeed();

// Is the robot going forward?
if (m iDirection == ciForward)
{
forward (0);
ReadMotorSensorSpeed ();
}
hi when will the schematics be available?
I'm working on it and will update the Robot website very soon.

Do you think it would be hard to add lidar or GPS to remove the need for the perimeter wire?
