Robot wheelchair “grows” legs, climbs stairs

If there is one thing the modern day wheelchair cannot do, it would be to climb up stairs. Of course, all of that might very well change for the better in the future, as the Chiba Institute of Technology saw a group of researchers led by Shuro Nakajima come up with a robot wheelchair which is capable of climbing over steps as seen in the YouTube video above. The robot wheelchair will not be able to work as fast as a Transformers transformation, but it does make full use of its four-wheel drive and five axes to overcome a previously insurmountable obstacle for regular wheelchair users.

As the user, you tell the robot wheelchair just where it is to go via a joystick, and the robot will automatically assess the surrounding terrain, making the relevant moves afterwards. Should you end up on uneven ground, the robot will control the seat in order to maintain a level field. It relies on sensors on its feet to figure out what’s on the ground, as well as “seeing” just how far it is from a step. Right now, the working prototype is classified as a conceptual wheelchair, but most of the motion has been worked out. The next step would be to fine tune the user experience, and this can only happen best via a live user test.

X1 Robotic Exoskeleton Helps Astronauts Exercise and Could Benefit Paraplegics on Earth

A lot of the technology we enjoy here on Earth started out as tech created for the space program. NASA has a very cool robot working on the International Space Station right now called Robonaut 2. New technology that has spun off from the Robonaut 2 program has been unveiled that could help astronauts exercise while in the weightlessness of space – and could possibly help paraplegics on Earth to walk again.

x1 robot exoskeleton

The technology is called the X1 robotic exoskeleton and was developed in cooperation with NASA and the Florida Institute for Human and Machine Cognition. The exoskeleton weighs 57 pounds and can be worn by humans to help assist or inhibit the movement of leg joints. By inhibiting movement, the exoskeleton could also provide resistive exercise.

The exoskeleton is worn over the legs with a harness that reaches up the back and around the shoulders. It offers 10° of freedom in the joints with four motorized joints at the hips and knees along with six passive joints that allow for sidestepping, turning, pointing, and flexing the foot. The system offers multiple adjustment points allowing the X1 to be used in a variety of ways. For instance, the exoskeleton could be used to help astronauts carry heavy gear on the surface of other planets and could possibly be adapted to military transport use here on Earth.

Robots come in many flavors. There’s the subservient kind, the virtual representative, the odd one with an artistic bent, and even robo-cattle. But, typically, they all hit the same roadblock: they can only do what they are programmed to do. Of course, there are those that posses some AI smarts, too, but Georgia Tech wants to take this to the next level, and build a ‘bot that can interact with its environment on the fly. The project hopes to give machines deployed in disaster situations the ability to find objects in their environment for use as tools, such as placing a chair to reach something high, or building bridges from debris. The idea builds on previous work where robots learned to moved objects out of their way, and developing an algorithm that allows them to identify items, and asses its usefulness as a tool. This would be backed up by some programming, to give the droids a basic understanding of rigid body mechanics, and how to construct motion plans. The Office of Navy Research‘s interest comes from potential future applications, working side-by-side with military personnel out on missions, which along with iRobot 110, forms the early foundations for the cyber army of our childhood imaginations.

NASA and IHMC building X1 exoskeleton to give us a lift, keep us fit in space and on Earth

NASA and IHMC build X1 exoskeleton to give us a lift, keep us fit in space and on Earth

It’s hard to deny the appeal of a space-bound robot like NASA’s Robonaut 2, fears of subversion notwithstanding. The space agency and Florida’s Institute for Human and Machine Cognition know it, and they want to put that technology into an exoskeleton with a nobler purpose than performing chores on space stations. The in-development X1 (not yet pictured) adapts the Robonaut’s skills to a body-hugging frame with 10 points of movement that might give humans an assist when they need it the most. In space, the X1 could automate and add challenge to exercise for astronauts in low gravity, or provide the extra muscle for that fabled day we return to manned surface exploration. NASA envisions its exoskeleton having more grounded uses as well, such as rehabilitation for leg injuries or walking for those who never had the chance. Although we’re not expecting a rapid turnaround knowing NASA’s lengthy schedules, we might see the X1 in use sooner than most such products in the wake of a purposefully quick development cycle — and, no doubt, a few interested customers here on Earth.

Japanese Robot Mimics Complex Calligraphy

It takes years for a person to learn how to write Japanese or Chinese characters. There’s good news though. Robots can do it a lot quicker. A research group has developed a ‘bot that can identify and mimic detailed brush strokes that are required to write these kinds of characters.

japanese calligraphy robot

The Motion Copy System was developed at Keio University by Seiichiro Katsura. It stores the gestures associated with traditional Japanese calligraphy, and copies them. All that one needs to do to train the system is to guide the robot’s arm with their hand, and it can precisely replicate their recorded brush strokes. Unlike traditional system, the robot can record and reproduce the force applied to the brush similarly to when people touch something.

The calligraphy replication ‘bot was presented at the 2012 Combined Exhibition of Advanced Technologies in Tokyo, Japan.

Zuru Robo Fish won’t go belly up that easily

Folks who have reared fish in the past as pets know that it is not as simple as letting your finned friends swim in an aquarium without a care in the world. You have got to make sure that the PH levels are correct, with the right kind of temperature as well as oxygen levels being maintained at all times. Not only that, there is this thing that you need to do as well from time to time – cleaning the tank of its gunk, goo and slime. The Japanese might have stumbled upon something that lazy pet owners would love to have – the Zuru Robo Fish.

They will not die, at least not biologically, need no food to survive, and will be able to swim in both fresh and sea water conditions. Retailing for $14.99 a pop, the Zuru Robo Fish might be the last Nemo lookalike that you will ever need to purchase. At least it saves you the trouble of explaining the concept of death to a young kid, no?

Rain Man Robot Builds Ramps With Thousands of Randomly Tossed Toothpicks [Video]

In what has to be one of the most wasteful ways to traverse stairs, Harvard’s Self-organizing Systems Research Group has designed a robot that builds its own access ramps by randomly flinging thousands of glue-covered toothpicks. When the pile eventually solidifies, it provides a sturdy support for the robot to climb. More »

Robots to assemble your IKEA furniture

One thing about bringing home IKEA furniture is this – you will need to do your bit to assemble the particular piece of furniture, and for folks who are not too great when it comes to the assembly instructions, there is help. It will most probably be far more expensive than paying a small fee to the IKEA man to assemble your furniture assuming this furniture assembling robot takes off, but it sure as heck is a novelty worth exploring. A group of researchers have managed to find a way to program robots so that they are able to convert a set of instructions into commands – followed by executing them, of course.

Niel Dantam, one of the researchers behind the project, said, “You want to somehow capture the important aspects of the human’s motion and transfer that to the robot. Think about how you’d tell someone how to make a cake. An adult might bend down over the counter to work while a child may stand on tiptoes.”

This algorithm speculated on robots assembling IKEA furniture on their own, as the IKEA furniture assembly system boasts of an extremely versatile architecture, making it ideal to test out such an algorithm which will definitely make full use of nearly all possible ways in delivering a robust and ideal mobile manipulation system. How much do you think such a robot is going to cost you?
