Introduction: Walking Shoes
I was reminded the other day of those tiny wind-up shoes. They would walk all on their own with a little crank. I figured using my know how and ingenuity i could make a full size pair in no time.
These shoes use a servo motor to drive them.
This project has been featured on Gizmodo, Thanks!
The Here is a video to show how they work.
Step 1: Supplies
For this instructable you will need:
1 3/4" Wooden Dowel
1 Full Rotational Servo with direct drive (Look at these instructables for how to: Direct Drive and Continuous Rotation)
1 4 AA battery pack
1 pair of old shoes
Step 2: Make the Pivot Arm
First you need to make a pivot arm which consists of:
2 1 inch dowel pieces
1 4 inch dowel piece
Use wood or gorilla glue to attach the 1 inch pieces to the 4 inch piece and let the glue dry over night.
You should have a nice s shape to work with
Step 3: Install the Motor
First you want to install the motor, take the shoe and drill a small hole. Next take the head off of the motor and push the smaller part through hole in the shoe and reinstall the servo head.
Next wire up the motor and test it out. I included a switch for easy turn off. I also added a small zip tie to prevent the motor from moving around
Lastly you want to glue the arm onto the servo head plate.
Step 4: Attach Other Shoe
I attached the other shoe just using a screw. I pre-drilled a hole into the wood and screwed the screw in with a very small screwdriver.
Step 5: Test It Out
Once everything is together a secure, test it out! you may need to make some mods depending on your shoes. My shoes worked pretty well right away although they do like to turn to the right a bit.
