New soft robot morphs from a ground to air vehicle using liquid metal

by

Imagine a small autonomous vehicle that could drive over land, stop, and flatten itself into a quadcopter. The rotors start spinning, and the vehicle flies away.

Looking at it more closely, what do you think you would see? What mechanisms have caused it to morph from a land vehicle into a flying quadcopter? You might imagine gears and belts, perhaps a series of tiny servo motors that pulled all its pieces into place.

If this mechanism was designed by a team at Virginia Tech led by Michael Bartlett, assistant professor in mechanical engineering, you would see a new approach for shape changing at the material level. [Read more…] about New soft robot morphs from a ground to air vehicle using liquid metal

Scientists unveil robotic grippers ‘delicate enough to lift egg yolks and precise enough to lift a human hair’

by

Engineering researchers from North Carolina State University have demonstrated a new type of flexible, robotic grippers that they say “are able to lift delicate egg yolks without breaking them, and that are precise enough to lift a human hair”. (See video below.)

The work has applications for both soft robotics and biomedical technologies.

The work draws on the art of kirigami, which involves both cutting and folding two-dimensional (2D) sheets of material to form three-dimensional (3D) shapes. [Read more…] about Scientists unveil robotic grippers ‘delicate enough to lift egg yolks and precise enough to lift a human hair’

MIT unveils dexterous robotic hands that can ‘manipulate thousands of objects with ease’

by

MIT’s Computer Science and Artificial Intelligence Laboratory has revealed a dexterous robotic hand that scientists say can “manipulate thousands of objects with ease”. (See video below.)

At just one year old, a baby is more dexterous than a robot. Sure, machines can do more than just pick up and put down objects, but we’re not quite there as far as replicating a natural pull towards exploratory or sophisticated dexterous manipulation goes.

OpenAI gave it a try with “Dactyl” (meaning “finger” from the Greek word daktylos), using their humanoid robot hand to solve a Rubik’s cube with software that’s a step towards more general AI, and a step away from the common single-task mentality. DeepMind created “RGB-Stacking,” a vision-based system that challenges a robot to learn how to grab items and stack them.

Scientists from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL), in the ever-present quest to get machines to replicate human abilities, created a framework that’s more scaled up: a system that can reorient over two thousand different objects, with the robotic hand facing both upwards and downwards.

High-energy shape memory polymer could enable robots ‘flex their muscles’

by

A high-energy shape memory polymer could someday enable robots to “flex their muscles”, according its developers.

When stretched or deformed, shape memory polymers return to their original shapes after heat or light is applied.

These materials show great promise for soft robotics, smart biomedical devices and deployable space structures, but until now they haven’t been able to store enough energy. [Read more…] about High-energy shape memory polymer could enable robots ‘flex their muscles’

Scientists use ‘swarmalation’ to design active materials for self-regulating soft robots

by

During the swarming of birds or fish, each entity coordinates its location relative to the others, so that the swarm moves as one larger, coherent unit.

Fireflies on the other hand coordinate their temporal behavior: within a group, they eventually all flash on and off at the same time and thus act as synchronized oscillators.

Few entities, however, coordinate both their spatial movements and inherent time clocks; the limited examples are termed “swarmalators”, which simultaneously swarm in space and oscillate in time.

Omron releases new 3D vision sensor for robot arms

by

Omron has released its new FH-SMD Series 3D Vision Sensor, which can be mounted on a robot to recognize randomly placed bulk automotive parts in three dimensions, enabling space-saving assembly, inspection, and pick and place, which are difficult with conventional robots, and improving productivity.

Production workers are hard to come by these days, and labor costs have risen sharply, says Omron. Manufacturers are now facing intense pressure to automate processes that rely on the senses of experienced human workers.

Moreover, production workers now need to work harmoniously with machines to raise productivity amid the Covid-19 crisis. In particular, the automotive industry requires vision sensors as the eyes of robots that are indispensable for automation because it is difficult for machines to recognize positions and postures of various complex shaped parts.

Origami-inspired miniature robot could open new era of surgical robotics

by

By Lindsay Brownell, Wyss Institute, Harvard University

Minimally invasive laparoscopic surgery, in which a surgeon uses tools and a tiny camera inserted into small incisions to perform operations, has made surgical procedures safer for both patients and doctors over the last half-century.

Recently, surgical robots have started to appear in operating rooms to further assist surgeons by allowing them to manipulate multiple tools at once with greater precision, flexibility, and control than is possible with traditional techniques.

However, these robotic systems are extremely large, often taking up an entire room, and their tools can be much larger than the delicate tissues and structures on which they operate. [Read more…] about Origami-inspired miniature robot could open new era of surgical robotics

Japan Post and Yamato to test delivery robots in Tokyo

by

Logistics and snail-mail delivery giant Japan Post is partnering with Yamato, one of Japan’s largest door-to-door delivery service companies, to test delivery robots on the streets of Tokyo, according to Nikkei.

The robot the two companies are using was built by a local company called ZMP, which appears to specialise in autonomous mobile vehicles, be they delivery robots or cars.

This particular one is called “DeliRo” (main picture), probably short for “delivery robot”. [Read more…] about Japan Post and Yamato to test delivery robots in Tokyo

How to Choose A Gripper for Your Collaborative Robot

by

Most modern robots are built with both affordability and practicality in mind. This is because there is work that robots can do really well, and there are some simple things that human beings can do better than robots.

It is for this reason that collaborative robots have gained popularity in all major industries – robots that work alongside humans to not only increase productivity, but also safety in facilities.

Collaborative robots can be programmed to do almost any task. [Read more…] about How to Choose A Gripper for Your Collaborative Robot
