A social network for robots has gone live. MyRobots.com hopes to connect bots and smart web-enabled objects together in a type of "cloud robotics." The goal is to augment devices capabilities by off-loading computation or other task to the "cloud." This pushes robots beyond their physical and software limitations.

 

Users of the service can create apps to aid in adding to a bot's function. For example, a robot has a camera but does nothing with it but stream video. A cloud based app would give this bot image recognition, navigation, object tracking and the like to that image.

 

Once the owner's bot is connected to MyRobots.com, it can be monitored via the web, sent commands, return updates, and run custom applications. At the moment only a handful of robots are compatible with the social network. However, Arduino based devices and PCs can connect to the system.

 

A serial to Ethernet gateway allows  most non-connected bots to hop on the network. At $77 USD a piece, connecting various old "dumb-bots" may have to wait.


 

My question, can a virtual robot connect to MyRobots? If so, can improvements be made to the virtual-bot?

In this new digital world, young people now grow up playing video games and surfing the Internet instead of playing games outside; clearly play dates are changing. Canadian company EZ-Robot wants to lead the way this new generation of youngsters play by bringing technology out of the screen into their hands.

 

To do this, they have released an easy to use, do-it-yourself robotics kit. But this kit takes robot building one step further by only providing you with the guts of the robot.

 

For $235, the kit provides you with three standard and two rotating servomotors, five sensors including an ultrasonic distance sensor, wireless tracking camera, wireless Bluetooth controller, a battery pack, other parts and software to control your creation without the need for computer code.

 

Like we said, these are just the guts of the robot. The fun begins, when you chose which of your currently lifeless toys to which you will grant life. As long as the parts fit, you will be able to animate and program the robot using the included software and controller. For the advance roboticist, the EZ-Robotics kit also supports the iRobot Roomba and Arduino software platforms.

However, with the included software, you can program face recognition, object tracking and slew of other functions. You can even program your robot to be controlled by a Wii remote, joystick, or a touch tablet.

 

At the moment, EZ-Robot says they are sold out of kits. It might be too late to get this as a holiday present for your favorite nerd, but this kit is sure to make an excellent gift at any time in the year.  An excellent way to pull them away from the screen for a little bit and let their imagination run wild, as they turn into a mad scientist.


I hate to admit, but this is very much like LEGO Mindstorm NXT, minus the LEGOs.

The applications of robots as solutions to different psychological problems are just now being explored. A recent project in Japan is currently working to find robotic solutions to mental ailments suffered by its elderly, which makeup 20% of Japans total population. Masayoshi Kanoh, professor at Chukyo University in Japan, has developed a doll with the intent of providing therapeutic interaction older people suffering from depression or dementia. He calls his creating Babyloid. Like the name suggests, this robot simulates the actions and behavior of a baby in hope of providing elderly users with a sense of purpose.

 

Aesthetically, Babyloid has a fluffy cover and a robotic cartoonish face that can express emotions. The mouth is able to change shape to express smiles or frowns, the eyes have moving eyelids and even its arms move to resemble a human baby. It is 17 inches long and weighs about 4.8 pounds. (It looks cumbersome.)

Just like an infant, Babyloid cries, laughs and falls asleep when rocked back and fourth. It produces more than 100 sounds all of which are recordings of Kanoh’s daughter when she was a baby.

 

The robot can sense its surroundings because it features accelerometers, temperature, touch, pyro-electric and light sensors that allow it to react to its environment. Red and blue led lights embedded in the face, along with facial expressions and sounds, allow the user to know when Babyloid is happy or sad.

 

Babyloid at the moment is being used to conduct research in nursing homes throughout Japan.

 

The prototype so far has cost about $25,000 USD, and Kanoh expects to make around 10 more prototypes in the next two years. He estimates the final product to cost around $1,300 USD if it hits the market, however, there are currently no plans to for distribution outside of Japan.

Imitating nature is never easy. Even its most simple processes can prove to be very hard for scientists and engineers to duplicate.  But nature seems to provide Kåre Halvorsen, a Norwegian engineer, with a lot of inspiration for his work in robotics. Kåre Halvorsen, a.k.a. Zenta, has worked on a robot inspired by ants, and now he is expanding his genius in his MorpHex Project.

 

His new creation resembles a crab crossed with an armadillo. The shell of the robot is made from curved polycarbonate panels each controlled by a motor. The panels and their 25 servo motor give this hexapod RC robot, the ability to walk and dance the way you would expect a crab to do so. When all the panels are pulled in towards the center of the robot, the shapes of these panels reveal they are sections of a sphere, and MorpHex rolls into a ball like an armadillo.

The project started back in December of 2010 all based on a plastic globe. See the Hexapod robot project board.


Halvorsen has not made the robot capable of rolling but does intend to. Still, at this stage, MorpHex is capable of putting on a mesmerizing show. It is an elegant blend of mechanical and electrical design.

From the Japanese company, Asahi Kasei Fibers, comes Roboden, the world's first elastic "electric/data/USB" cable. The company manufactures the famous Spandex material; it is only fitting that they bring elasticity to electronics. Matching the human body's skin stretch factor, the cable can elongate up to 1.5 times its length.

 

Developed with robotics in mind. Roboden allows for robots to move, twist, and bend its data and power cables without losing connection. Imagine no more long slacked cables. The Roboden cable has a spiraled internal mesh wiring surrounded by an elastic shell. The wiring is very similar to the design of the "Chinese finger trap" (Finger puzzle).

 

An Asahi Kasei representative explained the reason, as they see it, behind Roboden; "When we talked to Professor Inaba at The University of Tokyo, he advised us that, for robots to be more like people, they'll need to be soft, so they'll need something akin to skin. And if you make skin, you'll have wiring in the skin, so the wiring will need to follow the contours of the robot. Therefore, to make robots with a soft skin, it's probably essential for wiring to be able to expand and contract."

 

Depending on the meantime between failures, Roboden would be a great option for CNC equipment. Having long cables strung about often cause snag issues. Since normal cables have no give, loss of power, signal, and disasters soon follow. I look forward to seeing more about this product.

"Woah, I'm ready to recognize myself." - Qbo, a robot

 

In a mission to make a robot that could "self-recognize himself autonomously when found in front of [a] mirror," Francisco Paz created "Qbo." The bot is set up with stereoscopic vision via two cameras, ultrasonic sensors, IR, speakers, LCD, head and base movement, and packed with object recognition software and Robot Operating System components. The algorithms "SURF" and "Bag of Words" are used through the OpenPV library to analyze images. "Festival" Speech Synthesis System from The Centre for Speech Technology Research (University of Edinburgh) is used to handle speaking. Julius handles the speech recognition. Among these is a plethora of other open-source software packages, too many to name.

 

In the experiment, Qbo images itself, and then was asked to analyze itself again in the mirror. It learned what it looked like, and then identified. I imagine, if Qbo saw another Qbo, it would say "hey, it's me." A conversation between two Qbos is sure to be like something out of the movie Total Recall.

 


 

Qbo is cloud connected, always expanding, in different colors, a mobile app. Paz has created quite the product microcosm. See more at the Qbo blog.

 

Paz created several companies, and thanks to the sale of one of them he is able to spend most of his time on developing Qbo. Doing what you want, is the dream of every engineer. Take inspiration from Qbo and Paz, get out there and create your own microcosm.
