Original Lock Clasp

Final Lock Clasp

The Lock Clasp had to be altered because in the original model, it didn't have enough surface area to "grab onto" the lock and turn when the servo moved. We changed it so that instead of grabbing onto the smaller ends of the lock, the lock clasp would actually run along the longer part of the lock and secure itself on each side of it.

Testing the Servo Motor

This video shows Mike's face when the OLED is starting up and the servo being controlled by two buttons on the breadboard, so that when clicked the servo will lock or unlock.

Testing the Keypad and OLED SCREEN

This video shows the password "1-2-3-4" being used to "unlock" the door and display the message "correct" on the OLED screen.

What sets us apart?

Retrofitting current locks rather than completely replacing them
- This makes for a product that can be integrated into existing hardware, ensuring that no dorm rules are broken with installation
Our prototype can adapt to a variety of locks
- This allows for the product to be usable in a variety of different lock situations seen within dorm halls
Only team that Mike struggled to give ideas to
- This deserves extra credit :) … maybe?

front of door

The Lock and Roll still allows you to still access your key hole so that if you ever wish to disconnect the system, you can still get into your dorm.

back of door (lock)

The Lock and Roll also allow you to unlock and lock your door with "the click of a button"!

Competitor's smart lock

Other smart locks have to be permanently attached to the door by taking off the pre-existing lock, which is not feasible in dorm halls.
