Introduction: Theo Jansen Machine
this walking machine was invented by theo jansen. his models are about 2m tall, up to 15m long, and are powered by the wind. to see how to make this battery powered click here https://www.instructables.com/id/Battery-powered-theo-jansen-machine/
Step 1: Materials
balsa wood - 2 different sizes
pins - about 14 per set of legs
2 very small pieces of dowel - i used bbq skewers
small metal tube cut into 8 pieces ~ 1cm long
hot glue gun
drill and small drill bit
Step 2: Cutting the Wood
this is what you need for each st of legs.
~ 4cm x8
~9 cm x2
lay the pieces out in the order that they will be pined together. pin the pieces together so that they can still move freely.
with the wire cutters, cut off the ends of the pins so they are only sticking out about 1/2cm.
put a little bit of hot glue on the end of each trimmed pin to prevent them from sliding out.
glue one piece of the metal tube to each leg.
repeat steps 2-5 until you have the ammount of legs that you want. i made 3 pairs.
bend the crankshaft in as many places as the ammount of legs you have. for example i had 6 legs so i bent it in 6 places.
slide each set of legs along the crankshaft and into place.
slide the dowel through the metal tubes on the legs on both sides and put a dab of hot glue on both sides of the tube to keep them from sliding up and down the dowel.
glue a piece of metal tube to another piece of balsa wood and glue the wood onto the dowels joining them together and feed the crankshaft through the tube. do this on each end.
bend the crankshaft so that you can easily turn it. then you're finished!
