Humanoid Robots

On Star Trek; Next Generation, Data was a humanoid robot, right? Actually, no, he’s an android, a robot built to look human. Humanoid robots resemble humans, and sometimes, only part of a human, like from the waist up. C3PO is a humanoid robot.

Building humanoid robots is a circle of learning. In order to build a walking robot, for instance, scientists had to figure out – in broad terms – how humans do it. Once a robot could do it, they studied its movements, learning more about how humans do it, and how to improve the robot’s performance. This has led to better prosthetics for humans, including powered leg prosthetics, ankle orthosis, and biological realistic prosthetics.

Theoretically, humanoid robots can be programed to perform many jobs that humans do, using the same tools humans use. Realistically, at this point, they are more specialized. Some are entertainers, others might be assistants for the sick and elderly. Wikipedia had photos of some of these specialty robots:

Topio is a Vietnamese ping pong playing robot that is 6’2” and 264 pounds.

Nao (pronounced Now) is French, and originally played soccer, but moved on to universities to assist with education and research. As of 2015, some 5,000 units of Nao were in over 50 countries. One Nao can dance, another performs stand-up comedy. The University of Tokyo bought 30, intending to train them to be lab assistants. (I don’t know how well that did or did not go.) At some point, the company was sold and Nao became Japanese. They have been used to help teach autistic children, train ISS crews, and assist the elderly. The most interesting item I found was that in a philosophical experiment, Nao robots were shown to have a basic sense of self-awareness. It is just shy of 2 feet tall, and weighs less than 10 pounds.

Enon, from Japan, was designed to be a personal assistant, and has no legs, but rolls along, so the bottom half looks something like a long skirt. It is self-guided, has limited speech identification (and production), and can carry approximately 1 pound in its arms. I found no information on its size, but the photo I saw indicated it was approximately half as tall as the man next to it.

The robots are coming! The robots are- Well, they’re already here. But they aren’t anywhere near as sophisticated as Data. If you buy one that plays soccer, but then want it to dust the living room, you’d probably have to completely reprogram it, maybe change out the arms, beef up the servo motors, and install more sensors.

Oh, never mind. It’s easier to do the dusting myself.

Hatra in History

As I put together my list of things to research for blogs (and my own edification), I put several of them in line to be done ‘soon’. I thought I had a fairly random method of choosing what to slap on that ‘soon’ list, yet here we are, looking (yet again) at what little is known about an ancient city.

Hatra was founded in the 2^nd or 3^rd century BC by the Seleucid Empire, which was established by a group of Greeks. But Hatra wasn’t in Greece, it was located in the northern part of modern Iraq. It was captured by the Parthian Empire (based in ancient Iran) probably in the 1^st century AD, and it then thrived as a religious and trading center. As an important fortified frontier city, Hatra resisted repeated attacks by the Roman Empire and others, but fell in 241 AD to invading Iranians.

Hatra had more than 160 towers and two walls - inner and outer - that circled an area 2 kilometers (1.2 miles) in diameter. It was a religious center, but it didn’t seem to care what god people wanted to worship; it adopted them all. The major temples were gathered together over 1.2 hectares in the middle of the city, dominated by The Great Temple, which at one time rose 30 meters (100 feet) into the air.

For many centuries, the Hatra ruins were the best preserved example of a Parthian city. Unfortunately, in2015 it was reported that ISIL was destroying the ruins. I did not find any report about how much – if any – of it might remain.

I did see some lovely pictures of the ruins, and they were impressive. I also found a list of rulers for this city, but I didn’t care about that. Archeologists studied the site at various times during the 20^th century, and there was some effort to preserve the site. But I have no clue about the topography of the city’s location, no idea where the people got their water and food, what they ate or wore. The only way I could possibly ‘use’ this information in a story would be as the ruins that Hatra has been for so long. And that seems like a crying shame.
