Stigmergic Robot Date: Feb 25, 2009 1:57 PM

We investigate ways for the exchange of information (explicit communication) among deaf and dumb mobile robots scattered in the plane. We introduce the use of movement-signals (analogously to flight signals and bees waggle) as a mean to transfer messages, enabling the use of distributed algorithms among the robots.

amputee's mermaid dream Date: Feb 25, 2009 1:38 PM

Comes this very cool story (with an amazing picture!) :)

February 24, 2009 5:58 PM PST Effects shop fulfills amputee's mermaid dream by Matt Hickey

Nadya Vessey's prosthetic tail is mostly constructed from wetsuit fabric and plastic molds, and covered in a digitally printed sock. Good: double amputee gets prosthetic legs so she can walk. Better: double amputee gets realistic-looking mermaid tail so she can swim. Awesome: it's developed and built by Weta, the special-effects company that did all the work for the "Lord of the Rings" movies, as well as "King Kong" and "The Chronicles of Narnia" series.Nadya Vessey's legs were amputated below the knee when she was a child due to illness. At one point, reports Stuff, a child asked her what happened to her legs and she told him she was a mermaid. The idea stuck with her, so she wrote to Weta Workshop in Wellington, New Zealand, two years ago asking for a mermaid tail. To her surprise, they said they'd do it. Now she has a fully functional mermaid tail with an attached suit, making her look practically just like a real mermaid (if, you know, mermaids were real). She can swim well and says the prosthesis feels quite comfortable. We're not sure if anything like this could go into mass production for amputees, but we wouldn't be surprised if 10 years from now there are mermaids swimming about in your local pool.

Subject: [Robotgroup] Robot Theme Park to Break Ground Date: Feb 25, 2009 8:46 AM


Coming in 2013, a robot theme park called Robot Land is being designed to entertain and educate human visitors, as well as provide a boost to the local robotics industry. Its location? South Korea. And its developer? Not Disney, but the South Korean government and private industry.South Korea, which considers robotics to be one of its key growth industries, plans to spend $1.06 billion to build two industrial theme parks - the first in Incheon, a port city west of Seoul, and the other in Masan, a southern industrial city. The parks will include exhibition halls, education and corporate facilities, and R&D centers, as well as amusement rides and stadiums for various robot competitions. Construction of the first park is expected to begin later this year, and may be partially open to the public as early as 2012. Ultimately, South Korea expects that the parks could help provide a significant boost to the economy and create as many as 18,000 jobs.

Subject: [Robotgroup] Electric Botanist Date: Feb 19, 2009 1:38 AM Please vote for my project the Electric Botanist so I have

a better chance at winning the Dell Social Innovation

Competition. Also, I would greatly appreciate suggestions

on how or where I could get funding to work on this

project. Third, anyone know of a job opening in Austin

for PCB, firmware, robotics, or programming related?

Below is a summary of the Electric Botanist. Please vote

('promote') it, its easy and fast, make a user name and

password. Check out and vote for some other entries too,

theres some good ideas.


Best regards, Josh Jordan

Summary of Electric Botanist: Robotic platform that strives to be physically simple, capable of running complex software. The system is four or three winches that control the position of a grabber. A camera is the primary sensor.

Software for this robotic platform will use image processing, artificial intelligence, machine learning, and image recognition techniques to perform care for plants. The following are some of the tasks possible on this platform:

Pruning damaged or moldy leaves

Show progress with time lapse by using the camera to record a picture of each plant every day.

Harvesting specific food items as they become ripe instead of all at once

Watering specific plants more or less than others

Removing weeds and pests mechanically

Early detection of any trouble

Allowing plants to thrive in ways that are not possible with traditional tools and methods

Deciding the most viable species for a specific environment

This device is also intended to be used for research. It can beprogrammed to carry out experiments and record data inherently without bias. It can automatically select plants with the best attributes to naturally improve genetics. Mechanical simplicity is the key component to this project. The goal is that anyone able to buy or build this physically simple platform would have free access to open source versions of complex software required to run it. If the price of this device can be kept below $500, anyone who can afford the PC to run the software can afford the device.
