This innovation is a modulating shoe tying machine that helps elderly and disable people to easily tie their shoes with the use of an Arduino Micro controller Uno, and 2 micro servos to tighten and loosen the laces of the shoe.
Step 1: Finalize the Idea & Materials
To start off the project, we needed to create a way to tighten the shoe laces efficiently. We brainstormed for ways to do this, and came up with a few. Ultimately, we settled with servos onto the side of each lace, and an arduino and a bluetooth module to connect to the shoe.
1 Servo coverings
1 shoe 1 pair of laces
Arduino Micro Controller
Step 2: Glue the Spools and Make the Case
In order to have a stable part to wrap the laces around, hot glue a spool to the top of each servo, making sure that they are stable enough to not fall apart when pulling forces are applied. To protect the servos, make a case that encloses the servo and allows the lace to still turn. I made a CAD file and then 3D printed it, but if you do not have access to a 3D printer, any case will do.
Step 3: Cut the Sole
To make a space for the arduino, we cut out the a rectangle in the sole. We will wire everything through the inside to make the shoe less bulky. Cut a piece of cardboard to cover the hole, but now there is a spot for the arduino in the heel.
Step 4: Glue the Laces
Cut down the laces so that they wrap around the spool a few times (not too short not too long). Glue them to the spool so that when the servo spins, the lace will wrap around the spool, tightening the shoe
Step 5: Paint the Shoe
Prepped the shoe and spray paint the entire shoe inducing the bottom. Added the shoe laces and tested.
Step 6: Electronics/code
We used and Arduino Uno Micro controller board, connected the servos to pin 9 & 10, the Bluetooth module was connected to 0 & 1 RX/TX. A basic Bluetooth controller app was found on Android play store and configured to turn the servos on/off. See code for the Break down of functions.
