1. REMOTE DOOR LOCK CONTROL Robert B. Schidle EKU, Dept. of Technology, CEN

2. 2 OUTLINE Motivation Introduction Problem Statement Proposed Solution Results Conclusions Future Work

3. 3 OUTLINE I created a sample door frame that will show the process of remotely unlocking the door. A stepper motor and the circuit board from EET 452 (Drives) is used to control the lock/unlock mechanism.

4. 4 OUTLINE Stepper motor mounted into the door frame. When X10 activates the board, the motor moves a screw to lock/unlock the door. Door automatically locks back into place when closed.

5. 5 MOTIVATION Going on vacation and you want someone to feed/water your pets but don’t want to give them your key. Apartment Buildings

6. 6 MOTIVATION Unlock your door to let someone in your house without getting out of your chair. Add-on to X10 home automation (they do not currently have a remote door lock/unlock component)

7. 7 INTRODUCTION Power by stepper motor and X10. X10 has been around for years specializing in home automation. Research: Telephone controlled automation (Sandweg, Nina; Hassenzahl, Marc; Kuhn, Klaus. International Journal of Human- Computer Interaction, Dec2000, Vol. 12 Issue 3/4, p401-414, 14p, 1 chart, 3 diagrams; (AN 4792889))

8. 8 INTRODUCTION Research: EADL Devices Tam, C.; Rigby, P.; Ryan, S. E.; Campbell, K. A.; Steggles, E.; Cooper, B. A.; Goy, R.. Technology & Disability, 2003, Vol. 15 Issue 3, p181-190, 10p, 5 charts; (AN 11620670)

9. 9 PROBLEM STATEMENT The ability to remotely unlock/lock a door using an electrical mechanism with decent security.

10. 10 PROPOSED SOLUTION X10 Attempted to try a solenoid for use in the door lock/unlock Purchased the X10 ActiveHome pack Installed X10 components to PC and tested them Used the MyHouse Online plug-in to make the X10 system available remotely and be secure.

11. 11 PROPOSED SOLUTION Frame/Stepper Motor Attempted to try a solenoid for use in the door lock/unlock Settled on using a stepper motor Built a door frame and attached the stepper motor to the frame side. Programmed the stamp microcontroller to turn a certain amount one way (thus unlocking) then turn a certain amount the other way (relocking). Stamp Code

12. 12 RESULTS Stepper motor works good at pushing out screw but seems to slip when screw is almost all the way out. Setup video

13. 13 RESULTS X10 does good at activating the circuit but I had to change microcontroller code so it would not loop forever.

14. 14 DEMONSTRATION A look at X10 Appliance Module and Active Home USB Device

15. 15 DEMONSTRATION Drives Board

16. 16 DEMONSTRATION Screw extracted out of latch hole PC control video

17. 17 DEMONSTRATION Car Cord Power Adapter & Power Supply

18. 18 CONCLUSIONS Overall, even with the bugs still in my project, I believe the results are good and are a good start to automating a home door lock with security behind it.

19. 19 CONCLUSIONS The capstone course has helped to show me that I can do things by myself and that I can invite new ideas if I put my mind to it. Without this capstone course, I would have never thought I would have been able to do this.

20. 20 FUTURE WORK Stop the screw from slipping on the motor entirely. Apply this to a real door frame. Add ability to lock door also. Suggestions?
