This 3D printed hand uses fluidic circuits (which respond differently to different input pressures) to create a soft robotic hand that only needs one input source to actuate three fingers independently.

Nano quadcopters are ideal for gas source localization (GSL) as they are safe, agile and inexpensive. However, their extremely restricted sensors and computational resources make GSL a daunting challenge. In this work, we propose a novel bug algorithm named ‘Sniffy Bug’, which allows a fully autonomous swarm of gas-seeking nano quadcopters to localize a gas source in an unknown, cluttered and GPS-denied environments.

Large-scale aerial deployment of miniature sensors in tough environmental conditions requires a deployment device that is lightweight, robust and steerable. We present a novel samara-inspired autorotating craft that is capable of autorotating and diving.

Scientists from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have recently created a new algorithm to help a robot find efficient motion plans to ensure physical safety of its human counterpart. In this case, the bot helped put a jacket on a human, which could potentially prove to be a powerful tool in expanding assistance for those with disabilities or limited mobility.

Listening to the language here about SoftBank's Whiz cleaning robot, I’ve got some concerns.
My worry is that the value that the robot is adding here is mostly in perception of cleaning, rather than actually, you know, cleaning. Which is still value, and that’s fine, but whether it’s long term commercially viable is less certain.

This paper presents a novel method for multi-legged robots to probe and test the terrain for collapses using its legs while walking. The proposed method improves on existing terrain probing approaches, and integrates the probing action into a walking cycle. A follow the-leader strategy with a suitable gait and stance is presented and implemented on a hexapod robot.

Robotics researchers from NVIDIA and University of Southern California presented their work at the 2021 Robotics: Science and Systems (RSS) conference called DiSECt, the first differentiable simulator for robotic cutting. The simulator accurately predicts the forces acting on a knife as it presses and slices through natural soft materials, such as fruits and vegetables.

These videos from Moley Robotics have too many cuts in them to properly judge how skilled the robot is, but as far as I know, it only cooks the "perfect" steak in the sense that it will cook a steak of a given weight for a given time.

Most hands are designed for general purpose, as it’s very tedious to make task-specific hands. Existing methods battle trade-offs between the complexity of designs critical for contact-rich tasks, and the practical constraints of manufacturing, and contact handling.
This led researchers at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) to create a new method to computationally optimize the shape and control of a robotic manipulator for a specific task. Their system uses software to manipulate the design, simulate the robot doing a task, and then provide an optimization score to assess the design and control.

Some impressive electronics disassembly tasks using a planner that just unscrews things, shakes them, and sees whether it then needs to unscrew more things.

The reconfigurable robot ReQuBiS can very well transition into biped, quadruped and snake configurations without the need of re-arranging modules, unlike most state-of-the-art models. Its design allows the robot to split into two agents to perform tasks in parallel for biped and snake mobility.
World Vision Kenya aims to improve the climate resilience of nine villages in Tana River County, sustainably manage the ecosystem and climate change, and restore the communities’ livelihoods by reseeding the hotspot areas with indigenous trees, covering at least 250 acres for every village. This can be challenging to achieve, considering the vast areas needing coverage. That’s why World Vision Kenya partnered with Kenya Flying Labs to help make this process faster, easier, and more efficient (and more fun!).

Pieter Abbeel’s Robot Brains Podcast has started posting video versions of the episodes, if you’re into that sort of thing. There are interesting excerpts as well, a few of which we can share here.

RSS took place this week with paper presentations, talks, Q&As, and more, but here are two of the keynotes that are definitely worth watching.
