The Real Robotics Lab at University of Leeds presents two Chef quadruped robots remotely controlled by a single operator to make a tasty burger as a team. The operator uses a gamepad to control their walking and a wearable motion capture system for manipulation control of the robotic arms mounted on the legged robots.

We’re told that these particular quadrupeds are vegans, and that the vegan burgers they make are “very delicious.”

Thanks Chengxu!

Elasto-plastic materials like Play-Doh can be difficult for robots to manipulate. RoboCraft is a system that enables a robot to learn how to shape these materials in just ten minutes.

State-of-the-art frame interpolation methods generate intermediate frames by inferring object motions in the image from consecutive key-frames. In the absence of additional information, first-order approximations, i.e. optical flow, must be used, but this choice restricts the types of motions that can be modeled, leading to errors in highly dynamic scenarios. Event cameras are novel sensors that address this limitation by providing auxiliary visual information in the blind-time between frames.

Loopy is a robotic swarm of one Degree-of-Freedom (DOF) agents (i.e., a closed-loop made of 36 Dynamixel servos). Each agent (servo) makes its own local decisions based on interactions with its two neighbors. In this video, Loopy is trying to go from an arbitrary initial shape to a goal shape (Flying WV).

A collaboration between Georgia Tech Robotic Musicianship Group and Avshalom Pollak Dance Theatre. The robotic arms respond to the dancers’ movement and to the music. Our goal is for both humans and robots to be surprised and inspired by each other. If successful, both humans and robots will be dancing differently than they did before they met.

Thanks, Gil!

Lingkang Zhang wrote in to share a bipedal robot he’s working on. It’s 70 centimeters tall, runs ROS, can balance and walk, and costs just US $200!

Thanks, Lingkang!

The private-public partnership with NASA and Redwire will demonstrate the ability of a small spacecraft—OSAM-2 (On-Orbit Servicing, Manufacturing and Assembly)—to manufacture and assemble spacecraft components in low-Earth orbit.

Inspired by fireflies, researchers create insect-scale robots that can emit light when they fly, which enables motion tracking and communication.

The ability to emit light also brings these microscale robots, which weigh barely more than a paper clip, one step closer to flying on their own outside the lab. These robots are so lightweight that they can’t carry sensors, so researchers must track them using bulky infrared cameras that don’t work well outdoors. Now, they’ve shown that they can track the robots precisely using the light they emit and just three smartphone cameras.

We present a new gripper and exploration approach that uses a finger with very low reflected inertia for probing and then grasping objects. The finger employs a transparent transmission, resulting in a light touch when contact occurs. Experiments show that the finger can safely move faster into contacts than industrial parallel jaw grippers or even most force-controlled grippers with backdrivable transmissions. This property allows rapid proprioceptive probing of objects.

This is very, very water resistant. I’m impressed.

I have no idea why Pepper is necessary here, but I do love that this ice cream shop is named Quokka.

Researchers at ETH Zurich have developed a wearable textile exomuscle that serves as an extra layer of muscles. They aim to use it to increase the upper body strength and endurance of people with restricted mobility.

VISTA is a data-driven, photorealistic simulator for autonomous driving. It can simulate not just live video but LiDAR data and event cameras, and also incorporate other simulated vehicles to model complex driving situations.

In the second phase of the ANT project, the hexapod CREX and the quadruped Aliengo are traversing rough terrain to show their terrain adaption capabilities.

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.

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?
