We are planing to make a voice controlled line following wheelchair as collage final year project. so what you suggest an gps module with prerecorded path or line following different color for different path
Start with Kp, Ki and Kd equalling 0 and work with Kp first. Try setting Kp to a value of 1 and observe the robot. The goal is to get the robot to follow the line even if it is very wobbly. If the robot overshoots and loses the line, reduce the Kp value. If the robot cannot navigate a turn or seems sluggish, increase the Kp value. Once the robot is able to somewhat follow the line, assign a value of 1 to Kd (skip Ki for the moment). Try increasing this value until you see a lesser amount of wobbling. Once the robot is fairly stable at following the line, assign a value of 0.5 to 1.0 to Ki. If the Ki value is too high, the robot will jerk left and right quickly. If it is too low, you won’t see any perceivable difference. Since Integral is cumulative, the Ki value has a significant impact. You may end up adjusting it by .01 increments. Once the robot is following the line with good accuracy, you can increase the speed and see if it still is able to follow the line. Speed affects the PID controller and will require retuning as the speed changes.
I have the clone of polulu qtr8 RC sensor you are using, how did you manage to use the clone one and still get a good reading? please help, I am only receiving random values.
Hello U have made a connection for TX, RX, GND, VCC on PCB is it for programing Arduino through FTDI? if not then for what purpose it is there? Also we can skip that right if we are programing Arduino directly using cable?
How to test that ir array is working or not Serial print showing analog values for each sensor output from 1000 to 1020 Also the bot is not calibrating on pushing button (actually I am using wires to touch to 5v and turning high instead of push buttons) and executing forward brake (0,0) function please explain errors . Are there any error in the code because I checked and not found any.
Sir how do you know where to put what parts? please also name all the parts in the vid? from where can we get these parts? and please make a vid on how we can load the code...like u did in this vid
Bro really replies to every comment. What a chad.
Yes i do 😊

I'm building my own IR sensor. I just finished one but I don't know how many more I need.
Is 2 sensors enough?
Nope not like that. Number of sensors increase the precision.
@@EDISON_SCIENCE_CORNER Thank you
Are you using analog or digital sensor?
Digital
@@EDISON_SCIENCE_CORNER were you able to improve the robot?

Include the library

Line following is the best
I have a question can I use the motor driver DRV8833 instead of DRV8835?
Noo
Without line also it can reach it designation???
No
What kind of QTR library version did you use?
Not the latest one. Just use the penultimate version
How do you perform the trail and error tuning for PID gains? What values do you start with?

I didn't use any tricks . It is giving good output readings.

Nice !
please use a better micro soldering iron while soldering SMDs and also use good soldering techniques.
good PCB !👌
Thanks for your suggestions..❤️
@@EDISON_SCIENCE_CORNER hello bro i want learn pid how can i learn?
What changes should be done if I use tb6612 motor driver
You have to change the code and design
Will it work on a VNH5019 Motor Driver Carrier? It's also Pololu
No...!
is it possible for us to get the PCB file 🥹 please sir 🙏
I wanted to buy a n20 600 rpm motor and the vendor said that that is fake. The max he said was 200 is this true?
No. Its available
I am using BFD 1000 5array sesor how i decrease sensitive of sensor potentiometer full deceased
Whats that
Sir please can you make a code for aurdino uno with same ir arrays and l298 motor driver please
Will make that
@@EDISON_SCIENCE_CORNER please I need it before 19
Hey, i saw your robot with three sensors, do you have a video about it... Im trying to build PID for three sensors.. could use your ideas.. thanks
You can bro
How can i increase the speed ?
Should i use high rpm motors?
You have to change the motor RPM
Can I use a protoboard pcb?
Yes you can
hello, can you do it with motor backward?
Whats that mean
Can 6v 2000rpm n20 motor is efficient ?
Yes
Can we use another motor driver. The one you used is too expensive because of shipping.
We can't use other drivers with this circuit
@@EDISON_SCIENCE_CORNER 🙁
Do you provide any courses or training
Next year only
Can i do with l298N motor drive
Yes but you have to modify the code
Can u mention what all are the SMd and through hole components, also if I use a 400 rpm motor and 1293d motor driver which battery should I use
You can check that in design
where is buy DRV 8835??
Aliexpress
What is U3 the smt component?
Voltage regulator
what is the H1 and H2 and u3
Voltage regulator and header pins for connecting motors
what will happen if I use 300 rpm motors?
It moves faster
It will be slow as shit
Then eat that shit
Why does latest library works but 3.1.0 doesn't
Inwrote the code using old library
Hello
U have made a connection for TX, RX, GND, VCC on PCB is it for programing Arduino through FTDI? if not then for what purpose it is there? Also we can skip that right if we are programing Arduino directly using cable?

Need the schematics for this project.

can i use any other motor driver?
Yes but need to change code
Hello.. Nice job..
I would like to ask u a question if u don't mind.
If i want the robot moves for only 4 circles and then stops, how can u code this?
We can do that with different methods
Can I use a breadboard instead?
Yes
whats is the R1
You mean
I cant seem to open your code from the google drive link you sent, could you send another one copy of your code please?
Ok
Sir can we use any other motor drive other than that because it's not easily available in my country
We can use. Then we need to redesign the circuit and code. Btw where are you from.
Awesome.
Can I substitute DRV8835 for DRV8833 ?
You have to check the datasheets of both. If the pins are the same you can use them. I have not tested
Where you buying all electronics components.
www.esclabs.in
Use smooth types which helps to reduce friction
Thats correct
Great design and video.
Thank u
sir good day may i ask for the dimensions of the robot because we need it for a competition thanks so much
12*12cm
Love it! - When will your PCB and complete robot be back in stock?
In a month may be

Speed will increase
How to increase speed?
You can change in code also by changing the motor
