A little touch of robot

This is a nice move forward for robotics. While it may take robots further along the uncanny valley (the weirdness we feel when presented with human-like robots), it certainly makes robots more useful in human-robot interactions.

One of the inimitable features of the human arm is its capacity for simultaneously doing heavy work with a soft touch. If this technology can enable a robot to do both, then it would be capable of doing all kinds of things in the home, such as lifting small chldren or elderly adults who have fallen. Sound like a great step forward for the factory or the home.

Thanks for this post. I read about this technology before and found it quite interesting with lots of potential applications. Robots will never be just like humans, of course, but I think the closer we can get to giving them some key human-like qualities, the more useful they can be in certain applications. This is one example.

That's a very good point, Chuck. My guess is that this technology will be proven out in industry long before we see it in the home.

I disagree with you, Elizabeth. A robot is a machine with a degree of autonomy, not a mechanized human substitute. Providing them with human-like qualities can be more of a hinderence than a help - it over-complicates them. It also helps us forget that they are nothing but machines, and the more predictable they are, the safer they are. You really don't want to see your Roomba going off at a tangent and chasing the dog out of the living room, do you?

I designed the same thing while at Sarcos in 1993.  It was a DARPA project putting tactile sensor on the robotic hand that we had developed previously.  Each of the 3 finger segments had arrays of squishy silicone bumps with floating couplers that deflected when pressure was applied.  That displacement was sensed by a capacitance sensor.  

It's funny how technologies recirculate after 20 years.

It worked quite well (for the stardards of the day) but it didn't make it to any mass production.

I agree, Elizabeth. But it's also exciting to see robots extend into so many other areas, from replicating animal movement to activities that are very functional without mimicking the movements of humans or animals.

No question that tactile sensing is very important robotics technology, and there seems to be many interesting developments in this area.  It's harder to imagine what applications would enable the technology to be used in consumer applications because of costs.

A decade from now, firmware development may be nothing more than software integration, grabbing vendor and third-party components, and meshing their APIs together to form a final system.
Design, simulation, manufacturability, and prototyping: All of these phases are being pushed forward and progressively by underlying technologies.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesn’t come from conventional, statistics-based tests but from accelerated stress testing.
There’s a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
Pressure vessels are part of common equipment utilized in plants to store liquids and gases under high pressure. It is certain that pressurized fluids will develop stresses in the vessel, which when exceeds failure limits, will lead to hazardous incidents and fatalities.
