One Giant Leap for Man, One Giant Leap for Robots!

Robots have been employed by a number of NASA’s missions in the past, particularly those to the Moon, where they have been used to scan the surface and collect samples and various kinds of data. NASA has also been a pioneer in semi-autonomous robots exploring the surface of Mars; the twin Mars rovers Spirit and Opportunity are still operating on the surface of the Red planet several years after their initial mission was completed. The Phoenix robot successfully landed on Mars last year and completed its 3-month mission. Moreover, NASA is preparing to launch soon a new generation Mars rover aka the Mars Science Laboratory while testing the ATHLETE rover for a mission to the Moon.

But none of these very cool robots have been able to walk—or build Japanese rock gardens.

In a presentation entitled “Realization of Moon Exploration Using Advanced Robots by 2020,” Toyota shared plans about the future use of its innovative Toyota Partner Robot series. Initially, these humanoid robots were designed to help with life down here on Earth, specifically with elderly care and assistance. A result of Japan’s aging population and a lack of labor force, they are able to perform a variety of tasks, including transporting passengers and helping citizens in need. Their application, however, is set to be taken quite a big step further—to the moon.

There, the Toyota Robots will assemble space tents and relay stations, as well as deploy solar array and use a telescope. Additionally, they will work alongside a Rover to collect further data of the moon. The presentation also showed them building a traditional Japanese rock garden, which is rather cooler than planting a simple flag. To perform these tasks, they will be equipped with a number of big upgrades. As the specs in the yellow table predict, they will have:
  • joints that are protected from regolith
  • a small capacity solar battery onboard
  • their internal status showing on screen on chest
  • arms exchangeable for different tasks
  • ability to jump with springs in legs
  • keep warm during night covered in a metal cloak
That last one paints quite the endearing picture of our robot helpers working all day and camping out beneath the stars at night on a lonely desolate planet. With 2020 being the proposed date, however, we are still a decade away from finding out whether this is yet possible.

Remote radio control of insect flight.

Department of Electrical Engineering and Computer Science, University of California at Berkeley and the Department of Electrical Engineering and Computer Science, University of Michigan, USA, and 3 School of Life Sciences, Arizona State University, USA;

Have demonstrated the remote control of insects in free flight via an implantable radio-equipped miniature neural stimulating system.

The pronotum mounted system consisted of neural stimulators, muscular stimulators, a radio transceiver-equipped microcontroller and a microbattery. Flight initiation, cessation and elevation control were accomplished through neural stimulus of the brain which elicited, suppressed or modulated wing oscillation.

Turns were triggered through the direct muscular stimulus of either of the basalar muscles. We characterized the response times, success rates, and free-flight trajectories elicited by our neural control systems in remotely-controlled beetles.

I believe this type of technology will open the door to in-flight perturbation and recording of insect flight responses.

Further, a new spy, the size of penny stamp, is about to become the new 007!

Retinal implant helps blind man see again.

A really great breakthrough in the fight against blindness!

This story sounds like it is taken out of a science fiction novel but news reports around the world say that Mr. Peter Lane, 51, from Stretford, has his lost sight partially restored using a new device under development by California-based Second Sight Medical Products.

The story is that Lane is one of several blind people who are testing the new device known as Argus II Retinal Stimulation System and he is the one who recently found fame in the media having his lost sight partially restored to the extend that he can now read some small words and navigate the outside world with increased ease.

According to Second Sight, the device consists of a small camera and an electrode-studded array implanted on the patient's retina.
