So are you saying that using cables and motor driven pulleys is a better solution ? Most robotic arms I've seen appear to have a motor located at the elbow joint that drives the equivalent of the lower arm either directly or through a

That's an awfully general question. I would expect any high school or 1st year college course or textbook to do a reasonably good job of providing you with the basic intuition behind derivatives and integrals. It would help if you co

Humans can be very precise when they need to be (ever try repairing any modern electronics ?) but yes they do that closed loop using both visual and tactile feedback.

I'm not thinking of something as dumb as an industrial robot. You would want a safety mechanism that detects nearby humans (say in the same room) and switches to low power mode if any are present. That way you can get work done at a

I still think that application is a dead end. Anything that has buttons on it these days (and increasingly so in the future) is likely to also have some kind of wifi or other remote and/or programmable interface so control of that mac

The parent comment makes a good point. If accurate positioning is an issue it seems like you would want a closed loop control system that measures and optimizes for that. The position measurement itself could be made using machine vision

That may be but if you want an equivalent robot arm driven by an ordinary motor you still need the torque. Otherwise you would need a completely different system of actuation. I've heard of "artificial muscle" systems but I

If all you want to do is push buttons there's probably a much simpler and cheaper way to accomplish what you want electronically.

I think a bigger problem is that there isn't really a good safe way to directly interface a human limb to a mechanical one. Conventional prostheses distribute weight over tissues that didn't evolve to carry those loads and are th

Do you think there's any chance of direct drive generating enough torque for a roughly human sized robotic arm with human like performance (say to lift a 20 kg load) ? The last time I looked into this it didn't look like that much

So give your human validator a lineup - not 1 match but say the top 5 matches plus a few chosen randomly from lower down the confidence list, presented in a random order with no information on which was the algorithm's top choice.

You're right, if I just click on a link to a file that's not a PDF in chrome (in this case it was a .ps) it does immediately download the file, but it at least displays the filename in the downloads bar below the main window. So a

Aside from the Python related stuff one thing that confuses me about this article is the claim than a browser can put files in your Downloads directory without you requesting that. Exactly what browser/HTTP feature allows that ? I don

I think you must have meant on making UF6 from yellow cake. Yellow cake and UF6 are not at all the same thing.

I don't have much experience with it myself but based on what you said it sounds like there's a real need to have the geometry definition language embedded within a full programming language, like the parent comment said. In the m

Just from reading the abstract that looks extremely speculative. Frankly you might as well try to make inferences about human behavior by studying aggression in bees.

Speculating about the motives of a species that may or may not be biologically similar to us and which, even if they are similar, may well be millions of years more advanced than us is very hazardous. I think these kinds of speculations le

The whole point of tools like OpenSCAD is that you can create complex 3D models without needing to use a GUI. I think this approach is most likely to appeal to people whose background is in programming where we often find that text based i

The probability that he is telling the truth is far far smaller than 5%. I would say maybe about 5e-9. He clearly lied about having degrees from MIT and Caltech and people who are known to have made such a major lie are surely much more li

My objection to your argument is that taxis and other car services existed long before Uber and Lyft, usually with some level of safety supposedly being provided by government licensing requirements for drivers. The big problem with taxis i

I'm not an historian or a lawyer so I'm not sure exactly what the founding fathers had in mind or if they even held a consistent view of the question. However two things seem clear to me. 1) In practice in the US today the "g

Yes, unfortunately as long as you have humans making laws they'll be full of contradictions and unintended consequences.

I think they did it wrong by trying to maintain too much control over the drivers. Either that or people and/or their political representatives just aren't that interested in ride-sharing. But I doubt that, because as someone wh

But what I said was that the "turned out to be too hard" part had nothing to do with binocular vision. I'm certainly not claiming that I had a fully robust solution but I'm pretty sure lens flares wouldn't be too ha

All of them - cleaning, cooking, laundry, etc. Everything that a human needs to do to maintain reasonable living conditions and would hire someone else to do if they were rich. EDIT: I think that if you could come up with a really good sol

The plan is that you don't get involved in any of that. All you do is provide a platform that allows customers and drivers to connect in an efficient way. If clients don't aren't willing to accept that then I guess they don

I think one of the problems is that we don't have the right people working on the right problems. Self-driving cars seem to have absorbed most of the world's high-level robotics efforts for the past decade or more. I was always s

I don't really understand why depth estimation using binocular vision is still a problem. I worked on this a bit a number of years ago and I thought I had scene matching working pretty well. The problem is I was trying to make it work

What if it were done in a different way though so that the app is really just an app that doesn't attempt to exert any control over the drivers ? In that case wouldn't the drivers really be independent contractors and not employe
