Here's a fun to build automata that combines K'nex and origami. It particularly works well with origami animals that fly or swim like dragons, birds, narwhals, dolphins, etc. But in this case, we're using origami pigs since it is 2019 The Year of the Pig. This instructable won't teach you how to make an origami pig but I found some instructions on youtube here .
Step 1: Here Are All the Parts You Will Need
Step 2: Make the Base
Step 3: Add the Support Frame for the Automata's Crank Shaft
Step 4: Build the Top of the Frame
Step 5: Install the Top of the Frame
Step 6: Build the Crank Shaft
Step 7: Install the Crank Shaft Into the Frame As Shown
Step 8: Make Origami Stick Puppets
Tape the green connector to the inside of the origami animal.
Step 9: Attach Origami Stick Puppets to the Crank Shaft As Shown
Note: The puppet stick is mounted through the hole in the white connector of the top frame.
Step 10: The Automata Is Complete and Ready to Turn On
Please let me know if you build this and any ideas for improving the design!
