Arduino Servo control

Using a windscreen wiper motor as a servo motor and an Arduino driving a MOSFET H bridge I made a very cheap and powerful servo motor.
I am currently using the error signal fed back into the H bridge for positional control and it works reasonably well.
The next step in the project is to implement a PID feedback control. Essentially I currently have P but I need to add I and D to increase accuracy and reduce overshoot etc.

first step to building an iron-man suite. nice work!

Great Great ..... I always wanted to make something like that.... Do you have a schematic or do you have something available !!! for sale maybe ???? let US KNOW just like me there is a whole lot of ppl who is dying to build something like this !!!!!

hi i was just wondering if you could show me some diagrams on how to conect it all up to iannor@wideband.net.au

Nice job, Are you useing PWM just like the traditional Servo motors (remote controlled cars etc) and a processor or are you using a op-amp as a comparitor between the two pots?

Either way its a nice project.

Very nice.

High torque I would imagine.

gidday, would this work to use motor as motion platform for flightsim.?

[zincdustdust]

What FETS are you using?

Nice video..!!

dang your room is clean!!! (sarcasm)

I could definitely use something like this for steering control on my tank! excellent work.
