Thanks for the video link. I've seen that Sarcos robot before, its very impressive.

At first I thought the word Sarcos had a meaning (like some kind of acronym? ... the Carnegie Mellon Sarcos label on the robot was confusing me), but from the Wikipedia I see it a company name, now owned by Raytheon. (I've heard of them, I think they make that small lorry sized Terahertz raygun?!). I see they also make that Exoskeleton which is very interesting. (I want a working Ironman suit ;)).

Do you work in America or are you at Uni over here (I see your posting location is set as UK - Bristol, to add to the confusion ;)).

Anyway, its a very impressive robot, especially that amount of engineering (it looks like it took a lot of time and money to build it). I especially like its speed of movement and its ability to balance while standing.

Anyway thanks again for the video link.

I moved over to the states to work as a researcher at cmu. It's a really cool robot. I'm in the process of working with a team to build a new humanoid which is cool.

:shock:

Wow very cool! 8) ... Sounds like you have a dream job there! ... do you have any photos or even a video?! :)

As for the question of making the body, the clay approach does seem the easiest, although its not exactly easy as each solution seems to be a lot of work and time. I've been looking into the home made CNC approach for a long time, but its a considerable amount of work and even then modeling the object on a computer isn't as easy as it at first appears. So the clay approach seems far less overall work.

As for that smooth finish look on the clay, it depends on the clay type. If its the air drying type, after modeling it and leaving it to dry, the artist can sand it down to get very good finishes on it, with some work. Thats probably the easiest solution. Artists seem to have many techniques to learn to work clay in different ways. For example, with wet clay, its possible to just smooth it simply with water on your fingers to blur out ruff bits. You can also try smoothing each bit of it slowly through a very thin plastic sheet (like cling film) as you move the sheet around the object, but the dry clay and sanding it approach is easiest.

Here's an amazing site, with some amazing looking robots. The Android 10 made with polymorph is very impressive and the full size Iron Man head prototype is made out of clay. :)
