I get the above error when I try to compile. The error points to lines 34 and 37. #include "DFRobot_HuskylensV2.h" #include "DFMobile.h" #include "Wire.h" // Create object HuskylensV2 huskylens; DFMobile Robot(4, 5, 7, 6); // Motor control pins for Romeo int centerThreshold = 50; // Tolerance for…

I got my code working. However the robot's reaction can be slow at times. For example when it loses site of the target. I'm not sure if it is my code or not. // Devastator_Robot_6.ino #include <Servo.h> #include <NewPing.h> //https://bitbucket.org/teckel12/arduino-new-ping/downloads/ #include "DFR…

[image] docdoc: Result *result = huskylens.popCachedResult(ALGORITHM_OBJECT_CLASSIFICATION); @williampretty is using getCachedCenterResult(). Looking at the code, this appears to be a specialized version of popCachedResult() returning a pointer to a Result that's more suitable to this spec…

Here is the latest revision of my code. The robot turns left and right and forward to follow the target. However when I remove the target completely it continues with the last move. // Devastator_Robot_5.ino #include <Servo.h> #include <NewPing.h> //https://bitbucket.org/teckel12/arduino-new-ping/…

It is what I intended for now. For testing purposes. I have more code to write. I have to eventually check the Y-Axis and stop when the robot gets too close to the target.

Also I would prefer if the robot stopped when it loses the target.

[image] williampretty: Basically I want the robot to move left right or forward to follow the target and stop if it loses sight of the target. How will you reach that point in your code if there's no detected object available? [image] williampretty: if (huskylens.available(ALGORITHM_…

I think I may have the else { stop(); } code in the wrong place. I want it to be the default if the target is out of sight.

I can't run your code and do the usual tricks that substitute for reading and understanding it, actual analysis. I would add to the code means for seeing where it spends enough time to be sluggish in order to focus. This might involve diagnostic printing, which made me look and wonder why you slowe…

Thank you for your input. Unfortunately my C++ programming skills are limited. I have no idea how to write a State Machine architecture.
