How do I connect the US Digital e4p encoders to my motors mechanically? Can i just extend the shaft motor and attach them or do i have to make a gear mechanism?
My motor has to move in one direction only.
**broken link removed**
Will I be able to use this to achieve my task? Will it go on the back shaft of my motors?
What is the angle of throw? And how do i determine which one i need?
@Sudarsan_EDA: Does the PIC18f4520 have MFM?
How do i make a quadrature encoder? I want to make two motors rotate at the same speed by using quad encoders. And can i, without anything else, make a robot move on a circle track using only quad encoders?
I suppose you mean that your robot shoots out of corners because of high speed. For that, i'd suggest you put memory in your system. Like implementing PID control.
Thanks, it cleared up quite a lot. And yeah, i'm supposed to implement PI on it. One more thing though, i will determine the Kp and Ki values by hit and trial?
Your system will be something like this:
Sensors->Comparator->Controller->H-bridge->Motors
I used LED/Phototransistor pairs for sensors, LM324 for comparator, PIC18f4520 controller, L298 for H-bridge, And 2 Dunker motors.
I am using an array of 10 LED/Photo-transistors to track a line. How can I implement PI control on it? I've did normal line tracking and I used PIC18f4520. I used the comparator outputs in logic to control speed of motors by PWM. Now i have to line track with PI control.
My system w/o PI...
I suggest that you go with ultrasonic sensors. I recommend the PING ultrasonic sensors from Parallax. They're super easy to use. They're 30 dollars apiece the last time I checked.
PI Control Query for motor control with PIC18
I'm using PIC18F4520 to make a line tracking robot. It has to use an array of 10 LED/Photo-transistor pairs. Now i have to implement PI control on the robot. I've already done normal line tracking with a couple of LED/Photo-transistor pairs without...
