Title: Automatic Door
Post by: granty1988 on Mar 30, 2011, 02:06 pm
Hi there I am looking at designing and making an automatic door system for my disabled brother, I have an idea of how to control it (arduino obv.), and to use a car central locking button receiver as the remote control part of it.  The problem i am having is what to use for the opening and closing mechanism. Any ideas or suggestions would be greatly appreciated. And of course i will let you guys know how the projects gets on the exhibition forum.

Using a commercial door-opening mechanism?

You could buy such an automatically closing doors, take the innards out and put a small powerful engines, or a small motor and some gears

A regular door with ropes and pulleys.  A DC motor to wind the rope forwards and backwards.  (the motor pulls it open, a hanging weight pulls it closed.)

Or just turn the + and - on the DC motor

Are there other requirements besides automatic opening?

e.g. a lock? ==> There are sketches about RFID tagged doorlocks.

How many doors you need to make? One or more?

Are "saloon" doors an option? Or must the doors close 100%?

Is your brother in a wheelchair? As this has implications for the width (and weight) of the door and how far it must open.

What's your definition of "cheaper"?

For instance, a linear actuator (with built-in potentiometer, which will likely be needed) could be used, but depending on the size of the door, could get expensive...

What's your budget for this project?
