Humanoid Robot for Spacewalks 93

We had a story on the Robonaut two years ago, but it looks like they've come a long way since then.

Basically, all the machine had to do was measure and cut wire. That's a pretty simple task, and the whole thing could have been finished in a week for a few thousand dollars. For some reason, though, the customer insisted that instead of using easily replaced, sensible cutting blades designed specifically for the machine, it had to use the custom made, diagonal cutters their assemblers were using to cut the stuff by hand. The reason being that the diagonal cutters were of a special material required for the job (a medical application). Of course, we could have easily made machine blades out of the same material for about 1/20 of the cost, but the customer insisted...
The end result: the machine took almost 2 months to complete and cost almost $15,000, it requires constant re-calibration because the cutters move a tiny bit with each cut, and it takes nearly an hour to change and align the cutters when they dull. (The design we proposed would have cut that time down to a few minutes)
Designing a machine to use tools designed for a human is always a bad idea. No matter how much you have invested in those tools, redesigning them to be used by a machine will always be cheaper.

Re:Still a bad idea (Score:2)
Again, based on my experience, it will still be cheaper to have 2 sets of tools, one set for humans and one set for robots. A machine-centric toolset and a machine to use that toolset, even in a "general purpose" situation, will always be much cheaper and easier to design, and the result will be more reliable, than trying to design a machine to use human tools.
Your hand is an incredibly complex system,.I had no idea how complex it was until I spent a year automating tasks previously done by hand. Replicating the tasks that can be done with human hands is hard enough, having to replicate the "grasping qualities"[1] increases the difficulty by at least an order of magnitude, and not just in design but in fabrication as well.
You are correct that the robot in my example only had to do one task, and it's a damn good thing! The fact that the task was so simple only lends further support to my arguement. Every additional task increases the difficulty and reduces the efficiency and reliability of the design. Multiply that by the increased difficulty and reduced efficiency and reliability inherent in designing around human tools, and you will quickly exceed the cost of designing a new machine-centric toolset. Add to that the fact that the machine-centric toolset will be considerably lighter and smaller than the human-centric one, and it totally boggles my mind that NASA is even considering their current course.
[1] meaning shape, friction, deformity, and all the other qualities a human tool is designed to take advantage of.

You may have a point initially, but in the long run the main reason to go to space is exactly that: space. The earth is, after all, only so large. If we all stay down here we will either have to 1) force people to stop having children (and kill the excess kids that sneak through the cracks), or 2) institute a regular program for killing adults (and eventually, killing them before they reach breeding age), or 3) let nature do it for us.
None of these sound too appealing to me. But moving out into space (note: not "moving to other planets") gives us a great deal more time to find a better solution. It doesn't solve the problem, but it gives us another thousand years or so to work out a solution.

Redundancy is also a reason why these researchers are developing such an intricate, versatile humanoid robot instead of using non-humanoid designs that would probably be easier to build and more reliable.

As to there being no legs, well, the lab is the Dexterous Robotics Lab, hence they mostly develop new articulated robotic hands and test with their current telerobotics capabilities. And the hands arent small. The forearms are a little large.. Robonaut just has really wide shoulders. The 'see-through' face, well, that is just a plastic head (and the designer told me that it was just a coincidence that it looked like Boba Fett) created using stereolithography and mainly there to hold the camera (eyes). You should see it without the coverings....
The problem with proportions when building these types of telepresense robots is that the motors/linkages/cables needed to power all the degrees of freedom in motion. Also, creating complex custom one-off circuit boards for motor contol have to fit in small places.. The brain is a big ol' VME rack (in the chest). The forearm and hand is a whole unit that can detach... all the motors to control the fingers are housed in the forearm.. not to mention all the wires running to and from the joints to sense positon and joint angles.
All in all, this is a functioning advanced PROTOTYPE. Im not sure what the probability is that THIS robonaut will ever fly (probably pretty low), but I know that the engineers plan to thermo and vibro test this prototype somewhere along the way. Functionality over aesthetics. Actually, the dexterity of the Robonaut hand is considerably better that a pressurized astronaut glove.
Plus, the last time I looked at an astronaut flying though space, that big bubble head didnt really give me a great impression of stardard human proportionality.

Not according to Honda's Asimo page [honda.com]. Their robot was designed to be used in human dwellings, which meshes nicely with the "robotic servants" theme that shows up in a lot of Japanese pop culture. Completely different design criteria vs. NASA's applications (NASA wants something that can build/maintain fiddly bits of the space station without requiring a human to suit up and go outside the station).
In summary, using Honda's design would not be a practical solution for NASA.

If you've had a look at the internals of the Nasa bot, you would have a better idea of it's sophistication. IIRC, they didn't start from scratch with their designs.
They actually got the basic mechanical architecture from a very old roboticist named Leonardo da Vinci. He had very detailed drawings of how to build a machine that could replicate much of human motion sketched out here and there in his famous notebooks.
After improving his designs and adding the motorized bits, they are far ahead of where the Honda team is with Asimo. The hands and arms are far closer to the human range of motion and capability. If they had to send Asimo to do the work, it would be easier to just throw a human out the air lock.
I'm not saying this to dis Honda, their job is quite impresive as well. But the Nasa team packed a lot more sophistication into their leaner and meaner package.
Oh, and yes, I think they did put Boba Fett's helmet on the robot to give it a little personality.

The system has been assembled, and integrated with the brainstem for pointing control and calibration. The next step will be integration with the visual cortex, and then insertion of the system into the robot's helmet, replacing the old cameras.
