Automata
how to build an automata
Supplies
You will need a sketch of the automata, square, tape measure, 3 tennis ball containers, 3 water bottles, scissors, saw, pliers, wire, wire cutters, hole saw drill bit, circle compass, glue, 1/4in. wooden dowl, cardboard
Sketch
Draft the detailed plans for your automata
Tracing Out the Circles
Using the tennis ball container as a template trace out 12 circles
Cutting Out the Circles
After tracing the circles cut them out
Gluing Circles Together
Next, take 2 circles, and glue them together for thickness and durability. repeat this process with the rest of the circles.
Finding the Center Point of Circle
Find the center point of the circles by using the tape measure and square
Making the Frame
Cut a 10" by 6" section of the box off to form the frame/block for your automata
Supports
Cut 2 6" squares out of the cardboard by measuring it marking it with the square and tape measure. The squares will be used as bearing supports
Cylinders
Cut off the top of the tennis ball container to make the cylinder using a utility knife
Connecting Rods
Using the dowel as a template wrap an 8" piece of wire twice around the dowel to create a loop, then wrap the rest of the wire around the dowel, create 3 of these
Connecting Rods
Hot glue the wire to the dowel to secure it repeat this process until all 3 connecting rods are finished.
Frame
Using the drill and hole saw make three holes each an inch apart from each other in the block/box for the cylinders. Install the reinforcing cardboard squares/bearing supports you made earlier in between the holes and hot glue them in place.
Assembly
Glue the dowels into the circles and put the wire loop on the center dowl before putting the next circle on to assemble the crankshaft. Assemble 3 of these, connect them together with dowels in the block/box.
Finished Product
Glue the water bottles cap down to the wooden dowels/connecting rods. then glue the cylinders to the frame with a couple drops of glue
Crank
Make a crank by cutting out a circle made of cardboard and gluing a piece of the dowel to it.
Pully
Make a pully system by cutting out two cardboard circles and attach them to the frame using a couple of pieces of the dowel and some hot glue. when you're finished, add the rubber band as a drive belt. your automata is now complete
