A system for designing and training intelligent soft robots

‘Evolution Gym’ is a large-scale benchmark for co-optimizing the design and control of soft robots that takes inspiration from nature and evolutionary processes

Let’s say you wanted to build the world’s best stair-climbing robot. You’d need to optimize for both the brain and the body, perhaps by giving the bot some high-tech legs and feet, coupled with a powerful algorithm to help enable the climb.

Although design of the physical body and its brain, the “control”, are key ingredients to letting the robot move, existing benchmark environments favor only the latter. Co-optimizing for both elements is hard – it takes a lot of time to train various robot simulations to do different things, even without the design element.

Scientists from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL), aimed to fill the gap by designing “Evolution Gym”, a large-scale testing system for co-optimizing the design and control of soft robots, taking inspiration from nature and evolutionary processes.

MIT unveils robot that can brush your hair

by

MIT has unveiled a robot that can brush your hair for you as you can’t be bothered because this is the 10,000th lockdown and no one has seen you for decades and your hair hasn’t even seen the light of day for at least a year. (See video below.)

MIT says the robotic arm is equipped with a hairbrush helps with brushing tasks and could be “an asset in assistive care settings”.

With rapidly growing demands on health care systems, nurses typically spend 18 to 40 percent of their time performing direct patient care tasks, oftentimes for many patients and with little time to spare. Personal care robots that brush your hair could provide substantial help and relief. [Read more…] about MIT unveils robot that can brush your hair

MIT CSAIL’s robo-starfish enables closer study of aquatic life

by

Scientists have invented a ‘robo-starfish’ which give us more insights into aquatic life, as Adam Conner-Simons, or MIT CSAIL, reports. (See video below.)

Biologists have long experienced the challenges of documenting ocean life, with many species of fish proving quite sensitive to the underwater movements of humans.

As a possible solution, computer scientists have been developing special marine robots that can stealthily move among their carbon-based counterparts. In 2018, for example, a team from MIT’s Computer Science and Artificial Intelligence Lab (CSAIL) fabricated a soft robotic fish that autonomously swam with real fish along the coral reefs of Fiji.

However, the complex dynamics of how water moves – and its ability to quickly ruin some perfectly good electronics systems – have made underwater robots especially difficult to develop compared to ones for air or land.

Scientists develop soft robot for exploration in the deepest underwater place on Earth

by

Scientists at Zhejiang University in China have developed a soft robot which has been able to navigate the Mariana Trench, the deepest part of the Earth.

The research team led by Professor LI Tiefeng from the Center for X-Mechanics at the Zhejiang University School of Aeronautics and Astronautics and Zhejiang Lab conducted inter-disciplinary research with its partners and pioneered in proposing the principle of pressure adaptation in mechatronic systems, and their findings were reported in the journal Nature.

Typically, at such depths in the oceans, a vessel without a pressure-resilient “armor” would be “destroyed by the overwhelmingly hydrostatic pressure”. [Read more…] about Scientists develop soft robot for exploration in the deepest underwater place on Earth

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.

Robots sense human touch using camera and shadows

by

Soft robots may not be in touch with human feelings, but they are getting better at feeling human touch.

Cornell University researchers have created a low-cost method for soft, deformable robots to detect a range of physical interactions, from pats to punches to hugs, without relying on touch at all. Instead, a USB camera located inside the robot captures the shadow movements of hand gestures on the robot’s skin and classifies them with machine-learning software.

The group’s paper, ShadowSense: Detecting Human Touch in a Social Robot Using Shadow Image Classification, published in the Proceedings of the Association for Computing Machinery on Interactive, Mobile, Wearable and Ubiquitous Technologies. The paper’s lead author is doctoral student, Yuhan Hu. [Read more…] about Robots sense human touch using camera and shadows

Piab introduces soft gripper range for industrial robots

by

Piab has introduced a soft gripper – or end effector – for industrial robots. The company says its piSoftGrip range is developed for the automation of the food and chocolate industry.

Piab once again extends the pi-SoftGrip family with a new pinch gripper developed for the automation of the food/chocolate industry. The vacuum-based soft gripper can grip sensitive and lightweight oblong objects with odd geometries and/or objects with an unusual surface.

piSoftGrip has two gripping fingers and a sealed vacuum cavity, all made in one piece, resulting in a simple and robust product. [Read more…] about Piab introduces soft gripper range for industrial robots

Software-based PLCs pose challenge to traditional hardware infrastructure

by

By Sharmila Annaswamy, IoT Analytics

Software is increasingly replacing hardware in industrial environments. Software-based programmable logic controllers (Soft PLCs) today are reliable, powerful and flexible.

Soft PLC adoption is expected to double between 2019 and 2025, posing an “innovator’s dilemma” for incumbent industrial automation vendors.

Actions taken by incumbents will prevent significant disruption in the near-term, but the long-term threat of soft PLCs will remain. [Read more…] about Software-based PLCs pose challenge to traditional hardware infrastructure

Present times require clever solutions, digitalisation, and process automation: How Y Soft has implemented robots in its offices

by

By Ondřej Krajíček, chief technology strategist at Y Soft

Since the world was turned on its head as a result of the Covid-19 pandemic, organisations in all sectors have been forced to transform the way they work, speed up their digital transformation projects and rapidly innovate their processes in a way they’ve never had to previously.

So far, we’ve seen organisations completely repurposing their offering to help in the fight against coronavirus, such as manufacturers producing PPE; we’ve seen staff rapidly reskilled, or even being offered from one industry to another; and we’ve seen organisations using technologies to create innovations in both software and hardware.

At Y Soft, we’ve been using our fleet of 3D Printers to contribute face shields to hospitals around the world, but we’ve also been implementing various innovations internally, to ensure our operations continue seamlessly while we’re not physically in the office.

Scientists develop ‘flexoskeletons’ that cost a dollar to 3D print

by

Engineers at the University of California San Diego have developed a new method that doesn’t require any special equipment and works in just minutes to create soft, flexible, 3D-printed robots. (See video below.)

The innovation comes from rethinking the way soft robots are built: instead of figuring out how to add soft materials to a rigid robot body, the UC San Diego researchers started with a soft body and added rigid features to key components.

The structures were inspired by insect exoskeletons, which have both soft and rigid parts – the researchers called their creations “flexoskeletons”. [Read more…] about Scientists develop ‘flexoskeletons’ that cost a dollar to 3D print
