A simple tool to enable remote neurological examinations

In the early weeks of the COVID-19 pandemic, clinics and patients alike began canceling all non-urgent appointments and procedures in order to slow the spread of the coronavirus. A boom in telemedicine was borne out of necessity as healthcare workers, administrators, and scientists creatively advanced technologies to fill a void in care.

Robot Swarms in the Real World workshop at IEEE ICRA 2021

Siddharth Mayya (University of Pennsylvania), Gennaro Notomista (CNRS Rennes), Roderich Gross (The University of Sheffield) and Vijay Kumar (University of Pennsylvania) were the organisers of this IEEE ICRA 2021 workshop aiming to identify and accelerate developments that help swarm robotics technology transition into the real world. Here we bring you the recordings of the session in case you missed it or would like to re-watch.

As the organisers describe, “in swarm robotics systems, coordinated behaviors emerge via local interactions among the robots as well as between robots and the environment. From Kilobots to Intel Aeros, the last decade has seen a rapid increase in the number of physically instantiated robot swarms. Such deployments can be broadly classified into two categories: in-laboratory swarms designed primarily as research aids, and industry-led efforts, especially in the entertainment and automated warehousing domains. In both of these categories, researchers have accumulated a vast amount of domain-specific knowledge, for example, regarding physical robot design, algorithm and software architecture design, human-swarm interfacing, and the practicalities of deployment.” The workshop brought together swarm roboticists from academia to industry to share their latest developments—from theory to real-world deployment.

Underwater robot offers new insight into mid-ocean ‘twilight zone’

An innovative underwater robot known as Mesobot is providing researchers with deeper insight into the vast mid-ocean region known as the "twilight zone." Capable of tracking and recording high-resolution images of slow-moving and fragile zooplankton, gelatinous animals, and particles, Mesobot greatly expands scientists' ability to observe creatures in their mesopelagic habitat with minimal disturbance. This advance in engineering will enable greater understanding of the role these creatures play in transporting carbon dioxide from the atmosphere to the deep sea, as well as how commercial exploitation of twilight zone fisheries might affect the marine ecosystem.

Subterranean investigations: Researchers explore the shallow underground world with a burrowing soft robot

We've seen robots take to the air, dive beneath the waves and perform all sorts of maneuvers on land. Now, researchers at UC Santa Barbara and Georgia Institute of Technology are exploring a new frontier: The ground beneath our feet. Taking their cues from plants and animals that have evolved to navigate subterranean spaces, they've developed a fast, controllable soft robot that can burrow through sand. The technology not only enables new applications for fast, precise and minimally invasive movement underground, but also lays mechanical foundations for new types of robots.

Electrohydraulic arachno-bot offers light weight robotic articulation

A team of researchers at the Max Planck Institute for Intelligent Systems in Germany and at the University of Boulder in Colorado in the US has found a new way to exploit the principles of spiders' joints to drive articulated robots without any bulky components and connectors, which weigh down the robot and reduce portability and speed. Their slender and lightweight simple structures impress by enabling a robot to jump 10 times its height. At the end of May, the team's work titled "Spider-inspired electrohydraulic actuators for fast, soft-actuated joints" was published in Advanced Science.

Highly maneuverable miniature robots controlled by magnetic fields

A team of scientists at Nanyang Technological University, Singapore (NTU Singapore) has developed millimeter-sized robots that can be controlled using magnetic fields to perform highly maneuverable and dexterous manipulations. This could pave the way to possible future applications in biomedicine and manufacturing.
