Robotic Insects Could DASH to the Rescue

The Dynamic Autonomous Sprawled Hexapod (DASH) is being outfitted to locate victims that are trapped in rubble.  RobotNext posted a blog on this invention back in October 2009.  This is a cockroach-inspired robot that can move quickly and speedily like its model.  Also, like its insect model, it can fall great distances and survive to run again.  You can see the video on You Tube of this robo-roach in action.  Check out the story below for the complete story.

Robots Use Tricks From Nature to Climb Walls

The latest projects of Amir Shapiro, head of the robotics laboratory in the Department of Engineering, Ben-Gurion University of the Negev in Beersheeba, Israel, are wall-climbers.  In keeping with an on-going theme of RobotNext, this article is about the robot/nature connection.  These robots are using techniques from nature to defy gravity.   One robot is based on the method that snails use in attaching to a vertical surface.  However, instead of mucus, the bots secrete a trail of glue to enable them to stick as they ascend the walls.  Another robot, this one inspired by cats and rodents, has four appendages with fishhook claws to assist  it’s climb up a rough surface.

A third robot uses a not-so-natural method of sticky tape on its wheels to climb vertical, smooth surfaces.  You can see this demonstrated in the video on the PhysOrg website.  The fourth is magnetic and can climb smooth metal surfaces such as a white board. 

Dr. Shapiro works in the area of research known as biomimetics, which involves using technology to mimic nature.  This field has produced many diverse types of robots such as climbing robots, grasshoppers, and snakes.  Check the links below to see the whole story on these climbing robots.

Hexapod Robot Controls Chaos to Make Right Moves

This remarkable looking little robot is using what would be called muscle memory in humans to adapt to travel over rough terrain.  Resembling a scorpion, it is designed to control chaotic movements and essentially make its motions non-chaotic.  What this means is that the hexapod robot can move autonomously over a rugged surface.  You can see video on the Scientific American site and read the rest of the story there too.

Robot Ocean Gliders

Researchers are preparing to send forth a swarm of underwater gliders for a mission to explore the tropical Atlantic.  Information on temperature, salinity, oxygen and chlorophyll content as well as the turbidity of the sea water will be measured and sent back to the scientists at the Leibniz Institute of Marine Sciences (IFM-GEOMAR) in Kiel, Germany. 

As reported on the website at IFM-GEOMAR,  “A very successful mission using a single glider took place between August and October 2009 in the Atlantic Ocean, south of the Cape Verde Islands. The robot carried out measurements along a more than 1000 kilometres long track autonomously, before it was recovered by the German research vessel METEOR. The data collected are accessible online at http://gliderweb.ifm-geomar.de/html/ifm03_depl05_frame.html.”

Now a fleet of these torpedo-like craft will venture out to document the ocean properties in the tropical Atlantic.  Read the entire story from TG Daily at the link below, and then see all other articles on this in the other stories link.

Recycled Robot Fish Teach Biology

After a holiday hiatus here on RobotNext, the posts return with this one on a robotic fish from recycled materials.  You can see the video at Inhabitat.com or click on the embedded link below for a small version.  The idea is to teach children about the movements of swimming fish.  I think this also teaches a valuable lesson on recycling materials before they end up in the ocean.  See the link below for the entire story and other videos.

Tiny Swimming Robots Could Be Modeled After Spiral-shaped Bacteria

Spiroplasma is a type of spiral-shaped bacteria that travels in a corkscrew type motion.  It accomplishes this motion by sending kinks down the spiral of its cell structure.  And, it turns out this method of propulsion is very efficient.  Essentially, it is using its entire body as a propulsion unit.  This may prove to be a great method for nano-sized robots to get around in a fluid. 

Applications for this tiny machine come mainly in the field of medicine.  Small robots could deliver medicine directly to a targeted cell or perform very precise surgeries.  Some micro-robots have already been developed for this purpose, but these little bots could be much smaller.  Read more about this possible development in the article below.  Also, check out the full-sized animation on the site by clicking on the thumbnail below.

Robotic Bees Could Save Crops

In September, I posted a Weekly Newswrap with a story about robo-bees.  Now comes this story about robot bees that could help save agriculture from the coming disaster caused by the mysterious bee plague.  This is the disease that has wiped out over one-third of the bee population in the United States.  Some estimates of bee deaths are much higher.  If a cure cannot be found for this Colony Collapse Disorder, perhaps these mechanical bees can help save crops that require pollination.  These robotic bees would be developed from a robotic fly developed by Rob Wood at Harvard University.  Read more about these “beebots” in this article by Corey Binns from the Popular Science website.

That strategy led Gu-Yeon Wei to suggest that Rob Wood morph an almond-size robotic fly he had developed into a fleet of autonomous bees, each capable of carrying out specialized tasks. Perhaps, they speculated, the “RoboBees” could supplement the pollinating duties of bees stricken by a mysterious affliction that’s killed 36 percent of America’s 2.4 million hives. If you build the bee body, Wei told Wood, I can make the brain.

In the future, an autonomous robot could haul the hive from field to field. STEP 2: Survey the Landscape Scout RoboBees leave the hive first and use their ultraviolet sensors to locate the same UV patterns on flower petals that real bees look for.

Snakebot For Your Heart

A snakebot is being prepared to carry-out cardiac surgery by a team of doctors at Cardiorobotics.  Their version of the snakebot is known are ARM or Articulated Robotic Medprobe.  It is a teleoperated robot consisting of a series of links.  In an earlier post on August 10, 2009, I wrote about this snakebot for heart surgery being developed at the Newport, Rhode Island company.  Because of the snakebot’s ability to bend into many shapes, it is being developed to assist in delicate surgeries.  Check out the stories below.  You can see a video of the original version of this snakebot surgeon on You Tube.

Cardiorobotics

The central element of our technology is a teleoperated probe consisting of a series of links.  The probe is highly flexible and thus either assumes the shape of its surroundings or can be reshaped. 

This teleoperated, highly articulated probe with a non-linear lumen is called an Articulated Robotic MedProbe or ARM™.

Robotic Clam Developed for Deep Sea Projects

Of all the creatures on Earth that I thought could be models for robots, I never would have picked the clam.  But now, mechanical engineers Anette "Peko" Hosoi and Amos Winter at the Massachusetts Institute of Technology, have done just that.  They chose to emulate the Atlantic razor clam, also known as the Atlantic Jackknife Clam (Ensis directus) because it is one of nature's best diggers.  Robot clams may one day help dig up and detonate buried underwater mines, researchers now reveal. They could also serve as smart anchors for robot subs or deep-sea oil drilling.  You can read more at LiveScience.com in the article by Charles Q. Choi.

Robotic Rat Follow-up

Spotted this follow-up article on the Scratchbot covered here several months ago.  In this update, the robot is showing off its abilities to search-out objects by touch.  No vision system is used.  This is a very novel approach and could have many search and rescue applications where the lack of light is an issue.  Check out the link below and also look at the video at the Electronics Weekly website.
