Let's Make Robots!

Robo Dragon

Hi, I'm a beginer in this kind of robotics so please hang with me if i ask stupid questions or don't know how to do simple things. This is a project I thought would be fun and a overall good challenge, so far all i have done is a prototype for the wing design. The wing should be able to fold in and fit next to the body. Ill post any updates in this blog and will start a project when i start making  the real robot, and not prototypes.

This robot will hopefully do the following:

UPDATE 24.April 2011: New video! :) I implemented automatic resetting of the legs positions before changing from forward/backward walking to left/right walking. … Read more

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...

pivots

 Hi all,

You probably read my blog and know I am working on a design for robot legs inspired by the legs of Theo Jansen's Strandbeest.

Below is a picture of a plywood prototype on its way to become version 6.

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:

Amazing homebuilt quadruped

Searching for robot videos on youtube I came across this japanese guys profile. The quadruped in the video has a really interesting leg structure, not to mention the extra drive wheels. Check out the videos, it just looks and moves amazing!

Nice little creature with legs on wheels. Or something like that. It doesn't jump, like Fritsl's creatures, but it is nice to look at. And to gawk at the fabricating techniques this guy masters.
