Robotic Ray with Rodent Cells

By Kate Stone Yes, researchers have finally created one of the things we have all been waiting for: A swimming robotic ray. Not an RC Car This isn’t a rubber stingray that works like a radio-controlled car or a programmable rover. This robotic stingray is powered and guided by light-sensitive rat-heart cells. Yes, you read that correctly. The project demonstrated a new method for building bio-inspired robots by means of tissue engineering. Batoid fish, such as stingrays, are recognizable by their flat bodies and long, wide, winglike fins. These fins…

New software developed by Carnegie Mellon University helps mobile robots deal efficiently with clutter, whether it is in the back of a refrigerator or on the surface of the moon. Technology 

The Human-Robot Virtuous Circle of Creativity

By Norman Rusin @normanrusin Artificial intelligence (AI) has been applied to many tasks, from fighting poaching to preventing illegal logging to separating an Oreo cookie. Although seemingly more mundane, this last task is leading AI researchers to a key path toward creating robots that can help humans in their environment and daily lives, exploring a characteristic of highly developed animals: creativity. And new Carnegie Mellon University software is helping robots get creative. Why Do We (and Robots) Need Creativity? Tina Seelig, who teaches creativity and innovation at the Hasso Plattner…

Crowdfunded 3D-Printed Robotic Hand Is a Winner

By Lorna Partington New 3D-printing technology is revolutionizing the medical field in many ways, but one new innovation is making a particular splash. The aptly named Dextrus, an amazing 3-D printed robotic hand, recently won the James Dyson Award in the U.K. and is now competing with other global design innovations for the Award’s coveted $45,000 international prize. Initially funded through crowdfunding site Indigogo, the Dextrus is expected to reach the mass market in 2016, proving that a life-changing scientific idea can succeed in our online age.   The James Dyson…

Better Understanding the Human Grip

The human hand is an evolutionary wonder: 26 percent of the bones in our bodies are in our hands. Now, scientists are coming to better understand the grip and special grasping ability of humans and other primates. In a new study, a research team found that even the oldest known human ancestors may have had precision gripping skills comparable to modern humans. This includes Australopithecus afarensis, a creature that predates the first known stone tools by about a million years. Manual dexterity is traditionally viewed as a key adaptation that…

Mind-controlled Robotic Arm

A new prototype mind-controlled robotic arm is the latest example of brain-computer interface technology being developed with the ultimate aim of improving the quality of life of people unable to use their own arms. We recently reported on robotic prosthetic arms for amputees. Those prosthetic limbs can be controlled by the users and also deliver a sense of touch. Now, a woman with quadriplegia has been able to remotely move a robot arm with signals from her brain. She has even been able to use the mind-controlled robotic arm to pick up…

With elastic joints and six legs that function like those of a stick insect, Hector is the only walking robot of its kind. (Bielefeld University) Engineering Technology 

World’s First Walking Robot Stick Insect

By Kate Stone A research team at Bielefeld University in Germany has taught the only robot of its kind in the world how to walk. Designed to be stick insect-like, the walking robot is called Hector has elastic joints and an ultralight exoskeleton. Hector is the result of an interdisciplinary project at the Center of Excellence Cognitive Interaction Technology (CITEC) involving researchers from the fields of computer science, biology, physics, and engineering. The walking robot is equipped with plenty of sensors, enabling it to learn to walk much like a…

Your Household Robot Is on the Way

A household robot to help with the daily chores is surely every busy person’s dream. But who would want a clumsy robot that’s always getting under your feet? That is the challenge being addressed by researchers at MIT. They have built a sophisticated robot and are teaching it to work together with people. In a recent article, we reported on the robots being put to work at the retail giant Amazon to serve our holiday shopping needs.  But the future may very well have interactive and collaborative robots in our…

Robots Fulfilling Your Amazon Orders

Robots are hard at work this holiday season in the warehouses and fulfillment centers of Amazon.com, Inc. (NASDAQ: AMZN). In time for the holiday shopping frenzy, the company unveiled its eighth generation fulfillment centers (where customer orders are processed) which now use a variety of gadgets including Kiva robots, vision systems, and a whole host of other software and mechanical innovations that would make Santa and his elves weep. Amazon is currently operating 10 of these new centers in the United States. Amazon gets a staggering number of orders throughout…

Running Robots May Be Inspired by Birds

In preparation for building better running robots, researchers have made useful discoveries about some of nature’s most energy efficient bipeds – running turkeys. Running birds have an impressive ability to run while minimizing energy cost, avoiding falls or injuries, and maintaining speed and direction. Researchers at Oregon State University have been trying to discover exactly how the birds do it. “Birds appear to be the best of bipedal terrestrial runners, with a speed and agility that may trace back 230 million years to their dinosaur ancestors,” says Jonathan Hurst, an…

Robotic Prosthetics for Amputees

Robotic prosthetics controlled by neuromuscular implants are now a clinical reality. These prosthetic limbs are giving amputees new opportunities in their personal and professional lives. Mind Control of Prosthetic Limbs In January 2013 a Swedish arm amputee was the first person in the world to receive a replacement arm that is surgically connected directly to his bone, nerves and muscles. He can control the robotic prosthetic with his brain. “We have used osseointegration (anchoring the prosthetic to the bone) to create a long-term stable fusion between man and machine. The artificial arm is…
