Some interesting and practical work from the Autonomous Systems Lab at ETH Zurich on using drones for search and rescue applications.


Japan’s edition of Hebocon (the “best worst robot competition”) took place at the end of last month, I think, and while we hope to get a bunch of really good videos at some point, here’s a tiny teaser fight that’s too good not to share.

On the left, we have “Transparent Robot,” which consists mostly of a GoPro pointing backwards, and a phone that displays the video feed from the GoPro pointing forwards, making the robot “invisible.” Or, “Hebocon invisible,” anyway.

And on the right, we have (possibly badly Google translated) “Morse in the Shell,” which is powered by the wind coming out of a blown-into shell:

And this is why Hebocon is awesome.

Soft robots equipped with variable stiffness actuators (VSA) are robust against impacts and are energetically efficient. However, due to the real springs in the joints, soft robots can oscillate even when the motors do not move. This makes the control of, for instance, the end-effector a challenging task. A new method is presented enabling to control the interaction behaviour of soft robots, which is called Elastic Structure Preserving Impedance (ESPi) control. The performance of ESPi control is demonstrated by numerous experiments on the VSA robotic arm David. This video is provided for "Elastic Structure Preserving Impedance (ESPi) Control for Compliantly Actuated Robots" published at IROS 2018 by Manuel Keppler, Dominic Lakatos, Christian Ott, and Alin Albu-Schäffer.

This DARPA program called Polyplexus is not about robotics, exactly, but it could be helpful to roboticists (along with a lot of other folks):


EPFL researchers, applying what they observed about insect wings, have developed a hybrid origami drone that can be stiff or flexible depending on the circumstances. When airborne, the structure is stiff enough to carry its own weight and withstand the thrust of the propellers. But if the drone runs into something, it becomes flexible in order to absorb the shock and therefore minimize any damage. This research, which is being carried out in Dario Floreano’s Laboratory of Intelligent Systems, has been published in Science Robotics.


XYZ Robotics is a startup from some of the folks who rocked the Amazon Robotics Challenges, and are now applying that experience to fast and robust robotic picking.

Back in 2016, Kayie Byl’s lab at UCSB started teaching JPL’s RoboSimian DRC robot, Clyde, how to skate:

As with most things, it’s even better at 10x:

Clyde had to go back to JPL for some upgrades, so UCSB has been working in simulation since then. They’re hoping to get the robot back at some point, though, and I’m assuming that the first thing they’ll be working on is getting it to do all of this on two wheels instead of four.

Hinamitetu’s latest gymnastics robot is equipped with a SUPERCAPACITOR! And cute little decorations.

Well, here’s one way to do reinforcement learning with physical robots:

Researchers from IBM Australia have recently demonstrated a prototype for a new, AI-based system that controls artificial limbs with just a user’s thoughts. The prototype translates movement signals from the user’s brain into executable instructions for robotic appendages. This approach combines custom-developed AI code with commercially available, low-cost, off-the shelf robotic hardware.

Always, always select the Oreos. Always.

Introducing mobile robots into the collaborative assembly process poses unique challenges for ensuring efficient and safe human-robot interaction. Current human-robot work cells require the robot to cease operating completely whenever a human enters a shared region of the given cell, and the robots do not explicitly model or adapt to the behavior of the human. In this work, we present a human-aware robotic system with single-axis mobility that incorporates both predictions of human motion and planning in time to execute efficient and safe motions during automotive final assembly. We evaluate our system in simulation against three alternative methods, including a baseline approach emulating the behavior of standard safety systems in factories today. We also assess the system within a factory test environment. Through both live demonstration and results from simulated experiments, we show that our approach produces statistically significant improvements in quantitative measures of safety and fluency of interaction.

The humanoid robot ARMAR-6 collaborating with a human worker in a bimanual overhead task and performing force-based bimanual manipulation, vision-based grasping, fluent object handover, human activity recognition, natural language based human-robot dialog and interaction, navigation among many other features on a use case supplied by Ocado. In a complex maintenance task demonstration, the robot was able to recognize the need of help of a technician based on speech, force and visual information.

If you’ve pre-ordered a Segway Loomo, this kit will let you turn it into a go-kart:

The 2018 Robotics Science and Systems (RSS) conference took place at CMU at the end of last month, and there are lots of videos now online, including keynotes, invited talks, and research presentations. We only have room for two here: the first is an early career spotlight talk from Maya Cakmak at UW.

And the second talk is a full keynote from Jun Ho Oh at KAIST.

The Bionic-Hand Arms Race

The prosthetics industry is too focused on high-tech limbs that are complicated, costly, and often impractical

A photograph of a young woman with brown eyes and neck length hair dyed rose gold sits at a white table. In one hand she holds a carbon fiber robotic arm and hand. Her other arm ends near her elbow. Her short sleeve shirt has a pattern on it of illustrated hands.

The author, Britt Young, holding her Ottobock bebionic bionic arm.

In Jules Verne’s 1865 novel From the Earth to the Moon, members of the fictitious Baltimore Gun Club, all disabled Civil War veterans, restlessly search for a new enemy to conquer. They had spent the war innovating new, deadlier weaponry. By the war’s end, with “not quite one arm between four persons, and exactly two legs between six,” these self-taught amputee-weaponsmiths decide to repurpose their skills toward a new projectile: a rocket ship.

The story of the Baltimore Gun Club propelling themselves to the moon is about the extraordinary masculine power of the veteran, who doesn’t simply “overcome” his disability; he derives power and ambition from it. Their “crutches, wooden legs, artificial arms, steel hooks, caoutchouc [rubber] jaws, silver craniums [and] platinum noses” don’t play leading roles in their personalities—they are merely tools on their bodies. These piecemeal men are unlikely crusaders of invention with an even more unlikely mission. And yet who better to design the next great leap in technology than men remade by technology themselves?
