NABiRoS humanoid robot from RoMeLa

NABiRoS Robot Makes Us Wonder Why We All Don't Walk Sideways

One of the many things that makes humanoid walking tricky is the fact that when we walk, we’re off balance almost all of the time. For some silly reason, our legs are positioned to the left and right when we spend most of our time walking forwards, which means that walking means constantly rocking sideways while also leaning in the direction we’re going. Most robots don’t try to walk like this, and the few that do tend to be very complex and difficult to manage.

At UCLA, Dennis Hong’s Robotics and Mechanisms Laboratory (RoMeLa) has come up with a robot design that’s a novel new take on bipedal walking. By doing away with anthropomorphic design and turning a humanoid robot sideways, they’ve been able to create a stable and agile bipedal design that’s simple and cheap at the same time.

Video Friday: Self-Racing Cars, Robot Grumpy Cat, and Where's Keepon?

On a Friday morning nine (!) years ago, I published a post with just one video and one line of text on BotJunkie.com, the robotics blog I ran at the time before joining IEEE Spectrum. That was the beginning of Video Friday. 

As more and more robot video content started showing up over the years, Video Friday turned into a way to keep you updated on everything that happened all week in one efficient (and hopefully entertaining) post.

At one point Video Friday grew to include something like 30 videos (if we’ve crashed your browser, we’re very sorry!). We’ve now toned it down to around 20 videos by being slightly more selective. But we’d love some feedback on how many videos you’d like to see every week.

So, if you wouldn’t mind helping us out with this tiny little poll, we’d really appreciate it.

Definitely let us know if you have other suggestions for how we could make Video Friday better for you, either in the comments below or more directly via email or Twitter.

Also, a special shout-out to everyone who started reading on BotJunkie.com and is still reading on here. Thanks for sticking with me. Just for fun, we’ll start off Video Friday today with five videos from some very early (2007-2009) Video Friday posts. Enjoy!

Researchers develop cockroach robot that flips itself with insect-inspired wings

Cockroach Robot Flips Itself With Insect-Inspired Wings

For the last several years, we’ve been following closely (and somewhat uncomfortably) the development of robot cockroaches. Depending on your perspective, it’s either good news or bad news that they seem to be spreading. As roboticists graduate from the original home of the robot cockroach at UC Berkeley, they’re taking roachbot research everywhere.

Chen Li was a researcher at Berkeley’s Poly-PEDAL Lab and Biomimetic Millisystems Lab, where he gave little legged robots cockroach-inspired shells to help them push through obstacles. Li now has his own lab at Johns Hopkins University: the Terradynamics Lab studies “movement science at the interface of biology, robotics, and physics.” At IROS 2016, he presented a paper demonstrating a new trick for legged robots with shells: Ground-based dynamic self-righting, or flipping over using wing covers like a real insect does.

BALLU Humanoid Blimp Robot

Meet BALLU, UCLA's Humanoid Blimp Robot

The 2016 IEEE International Conference on Humanoid Robots kicks off today. It’s taking place at the Westin Resort & Spa Cancun, which sounds awful, but at least there are some cool new robots, and one of the coolest has to be BALLU, from Dennis Hong at UCLA’s Robotics & Mechanisms Laboratory (RoMeLa). BALLU, or Buoyancy Assisted Lightweight Legged Unit (Professor Hong loves a good acronym), is a humanoid-ish robot with a body made of helium balloons and a pair of thin articulated legs. Since it weighs next to nothing, it never falls over, and can walk, hop, and perform a variety of other useful bipedal motions as long as you don’t take it outside on a windy day.

Researchers are developing robot-plant biohybrids

Robot-Plant Biohybrids Growing in European Laboratories

Flora Robotica is a project funded by the European Union whose goal is “to develop and investigate closely linked symbiotic relationships between robots and natural plants and to explore the potentials of a plant-robot society able to produce architectural artifacts and living spaces.” The overall idea seems to be that it would be cool to enhance the capabilities of plants by mixing in some robotics, and vice versa, combining plant growth with the structure and mobility of robots. Sure, why not?

Cyclocopter designed at Texas A&M

World's Smallest Cyclocopter Brings Unique Design to Microdrones

A cyclocopter is a weird sort of aircraft that uses airfoils rotating around a horizontal axis to generate lift and thrust. The concept was developed about a century ago, but these things are tricky to build and fly, so they haven’t, er, taken off as much as helicopters have. In fact, there’s only a small handful of research groups working on cyclocopters at all, and at the moment, they’re focusing on small scales. Professor Moble Benedict and graduate students Carl Runco and David Coleman at Texas A&M’s Advanced Vertical Flight Laboratory has been testing the smallest cyclocopter ever developed: It’s just 29 grams in mass, and could be a tiny step towards replacing helicopters and multirotors with something better.

Echodyne's metamaterial-based detect and avoid radar sensor

Metamaterial Radar Is Exactly What Delivery Drones Need

As we’ve pointed out over the last few years, there are some issues with the idea of urban or suburban delivery drones. Besides the fact that they’re illegal right now, the biggest technological problem is that none of the delivery drones that we’ve seen so far seem to have any kind of sense-and-avoid capability that could realistically deal with the challenges of urban airspace, including everything from other drones to light aircraft to birds to trees to overhead wiring.

There are some drones that try to use cameras for this, and at least one that relies on lidar, but for reliable all-weather sensing with the kind of range and resolution that you’d need for safe autonomous flight, the best answer might be to just do what aircraft have been doing for decades: use radar.

Robot Drone Man

Behind the Music: How "Robot Drone Man" Built His Flying Avatar

The most entertaining video we posted on Video Friday a couple weeks ago was almost certainly Robot Drone Man, a parody of this PPAP (Pen Pineapple Apple Pen) video, which for some reason has 150 million views on YouTube. Parody or not, Robot Drone Man actually exists, and it’s a project of Ilhan Bae, a researcher and futurist at the Korea Advanced Institute of Science and Technology (KAIST), who wrote in to tell us about it.
