What are the benefits of Artificial Intelligence in Robotics?

one comment

Happy New Year to all!  It’s been a while since my last post. Too busy. Now, I’m back.

————————————————————————————-

Robotics is not only a research field within artificial intelligence, but a field of application, one where all areas of artificial intelligence can be tested and integrated into a final result.

Amazing humanoid robots exhibit elegant and smooth motion capable of walking, running, and going up and down stairs.  They use their hands to protect themselves when falling, and to get up afterward.  They’re an example of the tremendous financial and human capital that is being devoted to research and development in the field of electronics, control and the design of robots.

Very often, the behavior of these robots contains a fixed number of pre-programmed instructions that are repeated regardless of  any changes in the environment. These robots have no autonomy, nor adaptation, to the changing environment, and therefore do not show intelligent behavior. We are amazed by the technology they provide, which is fantastic! But we can not infer that, because the robots are physically so realistic and the movements so precise and gentle, that they are able to do what we (people) do. Read the rest of this entry »

Electronic nose to detect harmful airborne agents

leave a comment

A prototype of an electronic nose to detect harmful airborne agents such as pesticides, biological weapons, gas leaks and other unwanted presences has been developed at University of California.

The “electronic nose” will eventually be developed into three platforms: a handheld device, which could be used for environmental monitoring, a smaller wearable version useful for monitoring air quality, and a smartphone-integrated system, which the team reports could detect a potentially harmful airborne agent.

This is a very important sensor to include into robots, as well.

Microsoft’s new sensors: Humantenna and SoundWave

one comment

After the Kinect sensor, Humantenna and SoundWave are two new sensors that Microsoft is working on together with the University of Washington in Seattle.

Humantenna uses the human body as an antenna to pick up the electromagnetic fields — generated by power lines and electrical appliances — found in indoor and outdoor spaces. Users wear a device that measures the signals picked up by the body and transmits them wirelessly to a computer. By studying how the signal changes as users move through the electromagnetic fields, the team was able to program the system to identify 12 gestures, such as a punching motion or a swipe of the hand, with more than 90 percent accuracy.

Humantenna requires users to wear a sensor. They are still working in its robustness.

SoundWave relies on an inaudible tone generated by a laptop’s loudspeaker. When a hand moves in front of the laptop, it changes the frequency of the tone, which the computer’s microphone picks up. By matching characteristic frequency changes with specific hand movements, SoundWave can detect certain gestures with an accuracy of 90 percent or more, even in noisy environments such as a cafeteria.

Human-[robot/computer/machine] interaction can get huge benefits from these two new sensors.
