DC motor and angle control.

angle control using small dc motors

if anyone can help me so i will be glad so much.how can i control angle in dc motor?in my robot arms there are 5 dc motors and there are 5 feedback cable.if it could be servo so i could do it easily.but i must servo control with dc motor.i want to use pic16f877 microcontroller.please anyones help me.thank all of

dc motor angle control avr

Hi there

It would be easier to control the robotic arm if you just used stepper motors
there are many available in electronics hobby stores.

hai its
not clear that what u want
1.hardware schematic ?
2.software?
3.block diagram?
easy to impliment fuzzy logic controller with the said thing.

For each motor You can use a dc driver and interface it to the micro

use potentiometer coupled to the dc motor shaft

You can use a cascaded control loop using a RST control algorithm to control the position of the motor shaft.
This method will give you a very good precision but it may take some time.

all right, this work i done, i design and control arm robot usign DC motor, the best using servo motor, i used AVR family, i used a MCU for a motor, MCU control motor via H-bridge and feedback encoder, u can choose Fuzzy or PID method to control angle !! good luck !!
