Carpal block prototype

Designing and printing the carpal block for the fingers proved a lot easier than I'd expected.

Now I've got to figure out that @#$#@ thumb joint connection.  :-s


  1. Wow, impressive design!
    Will you be publishing the design of this anywhere on the web?
    If not would there be any scope for collaboration? I'm an MSc Robotics student in the process of picking a subject for my dissertation and have a couple of ideas for such a project.

    You can contact me through the following blog

  2. How are you planning on actuating it? Servos are crazy cheap these days (look at, but why didn't you put actuation in from the beginning?

  3. Hi, found this via the reprap blog. I'd been doing a lot of thinking about anthropomorphic robots about a year ago, although I didn't get that far.
    One thing I noticed is that many robot builders design joints as hinges, which may not be the best model. I remember seeing some armour for sport that had an exoskeleton support for the knee. The cheaper versions used simple hinges, but the more expensive and comfortable ones used two hinges, one above and one below the joint.
    So anyway my point is that human joints are held together by tendons and rotate around curving surfaces, rather than hinges.

    I can see why hinges are appealing from a computer control POV, but I've always felt that they'll be missing something that makes it harder further along. For a telepresence system that might translate into awkardness when it comes to control.

    Hope I didn't come off obnoxiously. It's been a while since I wrote any comments.
