Gakken interview - for the record

Dear Rik,

Thank you again for cooperating in our magazine.
(And also for introducing about us in your blog too!)

Following is the questionarie that I want you to ask about your Theo Jansen style robot leg.

Animaris Ordis Parvus

So here's the whole story (so far).

In Japan people are crazy about Theo Jansen's art. To find out more about Jansen's creation, start here or browse the LMR pages tagged "theo jansen". Several exhibitions of his art have been organized in East Asia before, including Japan. Jansen even holds a special Japanese website or two.

Big in Japan?

Google and Youtube keep haunting me for my dead projects. Today I was found by an editor for Gakken's magazine "Otona no Kagaku" (Grownup's Science). The magazine's upcoming January issue will have a Theo Jansen theme. Jansen apparantly is very big in Japan. The magazine includes a miniature, wind powered model of a strandbeest.

Theo Jansen style robot leg: prototype #10: forget about brass!

Getting closer and closer. Today I needed to clear my head. I really were dreading mass producing my legs with all those brass pivots. During a nice walk in the sun, I figured I would try 10 mm beech smooth dowel rod.

Theo Jansen style robot leg: prototypes #8 and #9, I suppose

My Theo Jansen Leg is finally starting to become something reproducible. Every step in in this arduous journey has been aimed at reproduction. No robot needs just one leg. And also, I wanted to share my design with anyone who fancies a walking Strandbeest robot.


Update 25 feb 2009: New video demonstrating the first powered test. Maybe that should read overpowered test...

(The ugly green screens are an editing artifact. Imagine beatiful fades.)

Theo Jansen style robot leg: prototype #6

(continued from here)

I am busy with the tweaking and fine tuning of my plywood version of prototype #5. I had no idea this would turn into a different design I now call #6.

This photo shows #6 in its leftmost position. It just cannot reach the extreme. There are still several small bits of plywood touching that should not be touching. Again with the jig and with the saw!

 

Theo Jansen style robot leg: prototypes #4 and #5

Continuing where I left off (after a stiff binary interruption)...

This picture compares prototype #2 with an angled profile version:

The angled "L-profile" introduces a new property in the design: chirality. All of a sudden, it matters which direction you want to fold the joints. Compare the symmetric #2 on the right:

Theo Jansen style robot leg: prototype #2 and #3

I started tinkering with "Theo Jansen legs" again (follow the link first if you don't know what that means).

I am prototyping in corrugated cardboard and trying to come up with a design that could be produced in large numbers (six at least) in plywood.

Theo Jansen style robot leg: prototype #1

For my dreamed symbiotic robots, I am looking for an alternative locomotion. For the passive robot (the trailer) anyway. The active tractor probably needs tracks. I heard Theo Jansen say on TED (improving on the wheel, 4 minutes into the video) that his design for a legged creature is (theoretically) more energy efficient than wheels or tracks.
