The Japanese have taken another step toward making eerily human-like androids by creating one with a neural network that breathes life into the robot’s facial muscles, making them react to outside stimuli with the aid of a central pattern generator.The robot, named Alter, will be freaking visitors out at the National Science Museum in Tokyo soon, in an exhibit lasting a week.
The CPG’s neural network replicates neuron activity, allowing the android to mimic human movement patterns by way of its sensors, which respond to temperature, proximity and humidity. While there’s still work to be done to make the thing more humanlike, Engadget says you get peculiar feeling the robot is alive when facing it directly and observing the face at work.
The point of the project was not to move closer to mimicking humans, but to enable robots to ‘control’ their movements and twitches on their own. Researchers from Tokyo University and Osaka University are referring to this human looseness as “chaos”.
And it’s not just about Alter’s face: his head and arms will also respond to the stimuli. The machine will have a switch offering the opportunity to switch from more conventional ones to “chaos” mode. But it won’t be up to the human to activate it. Alter will decide for itself when to don the human mask when its sensors react to environmental readings.
The researchers tried to attach particular movements to particular situations and circumstances that might produce the movement in the world of human interaction.
Alter can already sing, but at the moment, the robot tends to freak people out with its sine-wave melody. Researchers are working on new models, presumably with better sound chips.
This means that when a stimulus creates a signal spike in the neuron, it creates a chain reaction with other neurons. This is something Professor Ikeue calls “coupled pendulums” – due to the way the chain reaction takes place in a rhythmical fashion, although Alter’s movements are anything but that, resembling rather his own signature type of movement.
Osaka University’s Professor Kouhei Ogawa, who also carried out previous work on humanoid robots with the Ishuguro lab, says that this time around, “Alter doesn’t look like a human. It doesn't really move like human. However, it certainly has a presence.”
He believes the special thing about Alter is its ability to interact without having painstaking pre-determined programming work from engineers. “Alter, moving for itself, can do so easily.”
Japan’s love affair with androids has produced a wealth of ideas that have firmly placed the country at the top of robotic innovations.
The country is due to have its own robot Olympics in just a few years, following Prime Minister Shinzo Abe’s countrywide vision for the future.

Chinese tycoon takes 8 humanoid robot maids shopping so they can carry his bags
A Chinese tycoon opted for an unusual entourage, taking eight “female” humanoid robots clad in yellow and red uniforms with him on a shopping spree. The man was seen purchasing luxury goods encircled by the silent but servile helpers.
The money-bag, who reportedly is the boss of the company that produces these robots, was photographed on April 15 in the southern Chinese city of Guangzhou as he undertook an outing to a mall to buy some rich man’s ‘essentials’, such as gold jewelry and other luxury products, local media reported.
The helpers automatically followed their “master,” some of which carried his purchases while others looked after his coat and water bottles, all to the amazement of onlookers.
The man of fortune, who was apparently pleased with the attention drawn to his extravagant ways, continued his adventures the next day. On 16 April, he took his green-eyed trouble-proof companions to the Wanda theme park, where he introduced the “girls” to the giant Optimus Prime statue from Transformers, the International Business Times reported.
However, not everybody was enthusiastic about the opulent display of wealth.
“My goodness! Walking around with ‘Robot Maids?’ Certainly not my cup of tea! What’s so big deal about it? Worst of all...robot maids holding water and towel for him. He’s not retarded, is he?” wrote Facebook user Han Yin Tan in commenting on Chung’s behavior.
However, there’s still a long way to go before artificial intelligence replaces humans, as a recent experiment employing robots as waiters has shown.
“The robots weren’t able to carry soup or other food steady and they would frequently break down. The boss has decided never to use them again,” said an employee of a local Guangzhou restaurant that resorted to using robotic waitressing services, as cited by Shanghailist.com.
“The robots can attract plenty of customers, but they definitely can’t reduce the need for human labor,” another human employee concluded.
