Tendon Driven Arms

Fri, 13 Sep 2013

Just time for a quick extra blog post…

This piece is intended as a matching flexible arm to go with the flexible legs.

The parts roll round quite nicely and glue together to make this flexible multi-part arm.

With the addition of a couple of long strips to act as tendons and a mighty claw we have a fully working robot arm!

The dimensions need a little tweaking but basically it works a treat!

    It works with a similar function.  I couldn't find a regular working download (there were dozens of robot models, some of them automatons) but I found this link:


    I hope you like it.

    Thanks, that’s fantastic! – RI
