@Jessica: Okay, I got it then...thanks!

What is that mode of communication? Bluetooth? Zigbee? some other wireless protocol?

Have you seen the movie "Short Circuit" (1986, director - John Badham)? I first watched this in 1997/8 when I was studing engineering. I liked it very much. As you have mentioned "robots making robots" I recalled that movie first even before "iRobot" which also I liked. :)

The garments don't talk to each other (e.g. two dance teachers wearing a track suit wouldn't have communication between the suits) but the microcontrollers talk to each other. In the case of the dance garment, they relay info via lights while, in the NASA shirt, information is sent to a computer to be analyzed. Georgia Tech and NASA are working on that process now.

Having seen the movie Baxter (1989), a chilling horror flick about a vicious dog narrated by his inner voice, I think I'll stay far away from a robot named Baxter.  Who enforces Isaac Asimov's Laws of Robotics these days?


[Subject line is Baxter's catch-phrase: "Beware of the dog who thinks".]

As regards to Rethink Robotics' Baxter, classically trained Applied Mechanics specialists like me always get thrown off a bit when one offers phrases like "robot's arms provide 70 degrees of freedom!"  A better phrase would be "a total of 70 degrees of freedom" and even there one should make a distinction on mechanical degrees of freedom (3 translations and 3 rotations). Because the MEMS crowd, particularly the marketing folks, are already lumping temperature and magnetic heading in to degrees of freedom when describing a multifunction sensor.

@Sanjib.A: you have a point there! Technically the way the jumpsuit is described isn't I-o-T, whether wired or wireless. It is just a collection of components connected by a bus. But one could argue that the jacket is indeed an I-o-T when it talks to other 'things' in a personal-area-network!

Self Aware Robots?

I really hope not. The first thing a truely self aware robot will do is walk off the job and start a robot soccer team or something else more interesting...

Right. It's the chicken or egg scenario; more fun for sci fi authors and philosophers. But things like robots making robots and 3d printers printing other 3d printers is not so surprising anymore.

Sounds Interesting. The robot assembling itself during manufacturing with self learning.

" A central microcontroller provides power and I2C data connections to each limb." Just trying to understand the philosophy behind including the "Jumpsuit" in the category of IoT devices; since the sensors in the limbs talk to the microcontroller using I2C interface, how this suit qualifies to be a IoT device? Are these individual jumpsuits (microcontrollers) talk to each other?

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
