Transformer Robot

This is more of a fun robot to have around. Anyone who has ever been a Transformer fan will probably have also been disappointed by the lack of automated “transforming” that goes on. But this robot, built by Kenji Ishida and JS Robotics, actually transforms from car to humanoid, and can walk around and fire missiles from its arms!

There isn’t much detail released about the robot, although one interesting thing is that it makes use of 22 servo motors to get the job done and actually transform. Servo motors are generally motors equipped with a sensor for position that allows an exact angular position. Using the sensor and the rotation of the motor, it can move to exact positions.

Altogether, it’s a super cool robot, and hopefully, we’ll see more on this prototype of the sort of science that goes on behind toys to make them cooler than most.

Robot Dragonfly

1

Wouldn’t it be nice if you could have an affordable flying camera that follows you around? You know, when you’re trying to film yourself skiing, set up a security system, or get a companion when you actively move around? Well, to such a concept, most would turn to the natural world. And what animal is well known for its ability to hover and move around quickly and stably? The dragonfly, of course!

Built by TechJect at Georgia Tech, this robot dragonfly features two pairs of wings at each end of the robot body. It’s very light, weighing less than an ounce, and able to hover for 10 minutes and fly for 30 minutes, powered by a lithium polymer battery. It has an on-board computer and multiple sensors that all allow for stable flight.

And what would one use such ability for? You could take aerial photography, or spy on your neighbors, or use it as a new gaming platform. If you had a swarm, you could even use them for surveillance. Whatever the situation, though, these robotic dragonflies might be around very soon. They’re planning to be released at only around $99, which primarily aims to make these robots affordable for the common person. And with customization, such as shades of color, wing types, and more, everyone can fit his or her own tastes. What’s more, they can be custom-made with different on-board tools, such as GPS and wireless communication.

Book Scanning Bot

Most of us don’t find scanning books a particularly arduous task. However, most of us don’t realize just how many pages a book has, and how difficult it is to get an accurate scan of any given page. And that’s why the University of Tokyo made a revolutionary book scanning robot that could scan 250 pages a minute!

This speed is much quicker compared to the 12 pages per minute that the most modern scanners have. What’s more, these 12 pages per minute must be fed manually, whereas this robot makes scanning a breeze. But how exactly is this sort of a robot so special?

Well, this robot is special in a few ways. Most prominently, it abandons the concept of a flat scanner. Instead, it uses an actual camera scanner that calculates the curve of the pages as the pages are flipped, and ultimately accommodates the problem that the curve of the pages creates.

Another way that this robot is special is how it flips the pages of the book. The robot holds the spine of the book with a little tension so that the pages can be flipped with only a fraction of a  millimeter of movement from a robotic arm.

Before we all grab for the chance to use this super scanning tool, there are a few things to be noted. First, it has not been tested whether a books spine can handle this sort of pressure for extended periods of time, and this scanner also does not work for newspapers or other textual references that someone might need.

Despite these flaws, this robotic scanner is something to be marveled. It delivers scans with stunning clarity and accuracy, just like someone had ripped out a page of a book. With such perfection, and such technological advancement in the world of robotics, there’s no doubt that such technologies as these will be seen more in the future.

Juggling Disney Robot

If you want to juggle with someone who will never drop the ball, then come to Disney! Disney Research has recently been working on more interaction between entertainment robots and guests at its theme parts, that juggles and throws balls with a human player.

The robot uses the video provided by an external camera, and runs the information through a Kalman filter, which runs many calculations that include the uncertainties and approximate values of unknown variables. This filter allows the computer to make a more accurate measurement than it would with only a single measurement.

By using the calculations from the Kalman filter, the robot can accurately catch balls as long as they are thrown close to the robot’s hand. This hand is in a cup shape to catch the ball. The robot can then throw the ball back 8 ft to the thrower. Speeding up this process allows the robot to juggle three balls with a personas well.

But of course, if these robots are going to be communicating with people, they need to seem a little bit more… human. And so, this robot “follows the ball” with its eyes in the air, and runs one of many animations when the ball is dropped, including shaking its head or shrugging its shoulders.

Altogether, this robot aims to better robot-human interaction, while at the same time maintaining a safe distance. This robot shows that a world of robots is not all that far off, and their potential for entertainment is quite great. Almost like a performer that never fails.

Piano-Playing Swarm Bots

1

People often think of composing music as something innately human, that requires the creativity and flexibility of a human mind. Well, that may be true for a while. But for now, robots can actively play music already.

This group of swarm robots (Khepera III) was built by the Georgia Robotics and Intelligence Systems (GRITS) Lab. They are currently researching robotics in terms of mobile robotics and coordination, and they’re exploring the concept of “group-based leader-follower control,” which focuses on the interactions between robot topology. In essence, it focuses on having robots wirelessly linked for information, where the “leader” passes on overall instructions for the respective “followers” and they detect the locations of the other follower robots in order to carry out a procedure.

This group of piano playing swarm bots are an example of this technique. This robot “music wall” essentially plays notes when the robots reach a point on the board that details a certain note and pitch. These robots have velocity, acceleration, and sensor range constraints, and the leader essentially drives its respective followers to use the lowest number of robots needed (with respect to the time necessary to reach each note and the constraints that come with this restriction) and the least distance. In this video, we see the robots playing notes in accordance to Beethoven’s Fur Elise, and we also see that when a song is slowed down, the robots have more time to move, and fewer robots are necessary. Altogether, this algorithm requires careful spatio-temporal calculations (how much time in relation to distance and speed, so that the robots can get to the location on time), and communication between robots of relative locations on the music wall.

Ultimately, these swarm robots and their ability to follow a central leader and communicate each other makes them a potential tool for any situation. Although they act as separate robots, they communicate as one organism, with much potential for robots “working together.”

Prosthetic Ankle, AMP-Foot 2.0

5

Yet another prosthetic limb has entered the world. But why is this one special, you might ask?

The end goal of prosthetic limb development is always to make a prosthetic that can go above and beyond the original limb, uses energy efficiently, and emulates the natural motion of the actual body part.

Well this is what this prosthetic ankle does. Called AMP-Foot 2.0, this robot prosthetic is special in that it uses a smaller motor that constantly runs, rather than a larger motor that activates every time the prosthetic is moved. However, this smaller motor primarily relies on somethings as simple as rubber bands and springs to store potential motion energy.

Because of this interesting trait, this prosthetic ankle is special in that it has a lower net energy requirement, and the batteries can be smaller and weigh less.

And here’s a really long video of someone walking with the prosthetic.

Brief Update on Wave Gliders

Recently, I wrote an article about the Wave Gliders made by Liquid Robotics, and here’s a brief update with its interaction with Hurricane Sandy.

As many of you may know, Hurricane Sandy has been destroying much of the East Coast of the US. It has been ripping up trees and destroying internet connections, and hurting many people, and our hearts go out to them. But what about the watercraft that are in the hurricane itself?

Well, one Wave Glider called Mercury has survived. It can autonomously use wave motion, and it rode out winds of up to 81 mph (130 km/hr) near the coast of New Jersey. This is incredible considering the impact of the hurricane, and also more proof that the Wave Gliders are robust enough to survive natural disasters to continue monitoring the vast seas.
