Most of todays robots operate in isolation. The coordinated motion of tens of robotic arms in manufacturing plants, hundreds of wheeled robots on warehouse floors, or thousands of drones in night skies is no different: Each of those robots is unaware of its conspecifics and obeys orders issued by a central computer that leaves no room for unexpected interactions or unsolicited initiatives of the individuals, not to speak of emerging collective behaviors.

Robotic and biological individuals, however, have limited energetic autonomy, strength, perception, and decision-making abilities when taken on their own. The transition from solitary individuals to societies has been described as one of the eight major transitions in the evolution toward higher levels of biological complexity (1). There is ample evidence from biology that self-organized groups of individuals with limited capabilities can act as super-organisms that are more robust to individual failures and more resilient to environmental change and that can carry out more complex tasks and build more complex structures.

Computer scientists have taken inspiration from principles of biological self-organization among interacting agents with limited capabilities, loosely labeled as swarms, to devise distributed and adaptive algorithms capable of solving complex, noisy, and changing computational problems (2). The more recent field of swarm robotics shares similar scientific roots and ambitions (3), as described by

From individual robots to robot societies | Science - Science

A ROBOT is defined as an autonomous machine that can sense its environment, compute to make decisions and interact with the real world.

Recently, a video from Boston Dynamics highlighted the features of robots Atlas, Spot, and Stretch dancing to the song, Do You Love Me.

This viral video captures the essence of the advancement in the field of robotics and showed the dexterity of multiple robots in a music video.

In Malaysia, the picture that comes to mind when one is talking about robots, is an automobile production line a line of coordinated autonomous robots working precisely to weld and assemble parts that would otherwise take hundreds of skilled workers to achieve.

The adoption of robots by the automobile industry such as Proton and Perodua has proven the viability of using robots in the manufacturing process.

Another established use of robots is in the warehousing or material handling section where fleets of robots are used to move and manage huge stocks in the warehouse.

One good example of robot warehousing is the facility set up by Mr DIY for e-commerce fulfilment early this year.

Robots are also increasingly being introduced into households and the most common use of robots at home is the robot vacuum. The vacuum uses sensors to avoid objects while moving around to clean the house.

These are just some of the notable examples of how robots are used in our country. Depite that, we have barely even scratched the surface of the potential robotics holds in local industries.

The Covid-19 pandemic, however, has created greater awareness on the importance of automation as the way forward.

Due to the dependency on human labour, production capacities of factories shrunk when restrictions were imposed on the number of people allowed at the workplace.

The government recently launched the National Fourth Industrial Revolution (4IR) Policy and the use of emerging technology. Robotics was emphasised in the policy.

Indeed, there is enormous potential for growth in industries that are labour intensive. The agricultural sector is an example where the use of robots for planting, weeding, harvesting, and packing, can improve productivity.

More research and development must be conducted locally to ensure that the robots developed are able to fulfill the needs of the countrys many industries.

In a survey conducted by the World Economic Forum on the Future of Jobs 2020, 73% of companies surveyed in Malaysia said they would be adopting the use of robots (such as non-humanoid industrial automation and drones) in the next five years.

This will undoubtedly lead to a shift in the demand for new skill sets in the workforce and create new job opportunities.

Universiti Tunku Abdul Rahman (UTAR) has started to work on projects related to robots and automation to ensure that advancements in the fields of robotics can be adopted for practical use locally.

Talents in the field of designing, building, commissioning, and maintenance are crucial in robotics. Knowledge in mechanical, electronics, programming, control system, and artificial intelligence are essential to those planning to work with robots.

We must be prepared and equipped with the right knowledge to adapt to a future where the use of robots will be increasing pervasive.

THE RISE OF ROBOTS - The Star Online

A team led by University of Maryland mechanical engineering Professor Ryan Sochol has created a soft robotic hand agile enough to manipulate a game controller.

A team of engineers at the University of Maryland has built a three-fingered soft robotic hand that is sufficiently agile to be able to manipulate the buttons and directional pad on a Nintendo controllereven managing to beat the first level of Super Mario Bros. as proof of concept, according toa recent paper published in the journal Science Advances. The same team also built two soft robotic turtles (the terrapin turtle is UMD's official mascot) using the same multimaterial 3D-printing process that produced the robotic hand.

We traditionally think of robots as being manufactured out of hard, rigid materials, but the subfield of soft robotics takes a different approach. It seeks to build robotic devices out of more flexible materials that mimic the properties of those found in living animals. There are huge advantages to be gained by making the entire body of a robot out of soft materials, such as being flexible enough to squeeze through tight spaces to hunt for survivors after a disaster. Soft robots also hold strong potential as prosthetics or biomedical devices.Even rigid robots rely on some soft components, such as foot pads that serve as shock absorbers or flexible springs to store and release energy.

Harvard researchers built an octopus-inspired soft robot in 2016 that was constructed entirely out of flexible materials. But soft robots are more difficult to control precisely because they are so flexible. In the case of the "octobot," the researchers replaced the rigid electronic circuits with microfluidic circuits. Such circuits involve regulating the flow of water (hydraulics) or air (pneumatics), rather than electricity, through the circuit's microchannels, enabling the robot to bend and move.

Although this solution is ingenious, it brings its own set of challenges. These include the high cost (clean room facilities are required) and time necessary to fabricate those microfluidic systems and then integrate them with the system as a whole."Recently, several groups have tried to harness fluidic circuits to enhance the autonomy of soft robots," said co-author Ruben Acevedo. "But the methods for building and integrating those fluidic circuits with the robots can take days to weeks, with a high degree of manual labor and technical skill."

As an undergraduate, Acevedo worked in the lab of University of Maryland mechanical engineer Ryan D. Sochol, who was interested in moving beyond having to manually connect fluidic circuitry components to soft robots in favor of embedding these functions directly in the soft robotic systems. His team found the answer in PolyJet 3D printing, in which several different layers of materials are stacked on top of each other. The printer sets down one liquid layer, lets it solidify, then sets down the next layer, and so on.

"The incorporation of materials that differ in rigidity serves to enhance performance by allowing the material properties of specific features to be tailored to complement desired functionalities," Sochol et al. wrote in their paper. Components like diaphragms and O-rings must be able to deform during operation, so a soft rubber-like material was used to make them, while a more rigid, plastic-like material was chosen to make components that need to be stable (fluidic channels, access ports, and structural casings, for instance). Finally, the team used a water-soluble material to serve as scaffolding during the printing process, which was then removed from both the exterior and internal voids and channelsfirst by dissolving the stuff with water, then manually removing whatever scaffolding material remained.

Microfluidically controlled soft robots typically require distinct control inputs for every independently operated soft actuator. By integrating the fluidic circuit, the UMD team could operate the hand by varying the pressure strength between low, medium, and high. In other words, a single source of fluid could send different signals just by changing the pressure so that each finger could move independently.Even better, the one-step 3D-printing process for the hand and the two turtle-botsencompassing soft actuators (moving parts), the fluidic circuits, and robot bodytook a matter of hours, not days or weeks.

The team tested the performance of the robotic hand by having it play Super Mario Bros. To make Mario walk, the team used a low pressure, so only the first finger pressed the controller. The researchers used a medium pressure to make Mario run and a high pressure to make the hand press the correct button on the controller to get Mario to jump.

As for why they chose Super Mario Bros., Sochol told Scientific American that it was the very first Nintendo game he had played as a child. But the choice wasn't just a matter of nostalgia. The timing and specifics of the game are well-established; the robot hand simply needed to time its responses in accordance with the preprogrammed moves. And there are actual consequences for failure: a single mistake will cost Mario a life. The hand performed so well, it was able to successfully beat the first level of the game in less than 90 seconds.

"We are freely sharing all of our design files so that anyone can readily download, modify on demand, and 3D printwhether with their own printer or through a printing service like usall of the soft robots and fluidic circuit elements from our work," said Sochol, who estimates that printing one's own soft robots would cost about $100 using the team's software on GitHub."It is our hope that this open source 3D printing strategy will broaden accessibility, dissemination, reproducibility, and adoption of soft robots with integrated fluidic circuits and, in turn, accelerate advancement in the field."

Robotics is one of the major disruptive technologies helping multiple industries and organizations to boost productivity efficiently and effectively with moving, gripping, cleaning, and lifting objects. The world has already seen the development of multiple types of robots ranging from big industrial ones to micro-robots for assistance in the manufacturing, automotive as well as healthcare sectors. Recently, scientists and Robotics engineers have discovered that suction cups can be used in Robotics and their mission was also successful. Lets explore how suction cups in Robotics introduced wall-climbing robots into the world.

It has been observed that multiple robots are assisting human employees in some horizontal areas such as a body, object, water, floor, etc. But there are vertical failures when the robots are climbing high walls of tanks, dams, or boilers. Researchers have infused magnets into the robots for climbing walls made of certain metals. But the robots fail to climb walls that are made of stainless steel, aluminum, glass, and so on. Yet, multiple industries use these materials to build tanks and boilers with high vertical walls. Thus, human employees tend to risk their lives for manually cleaning these walls regularly.

That being said, researchers and scientists have introduced suction cups in Robotics for building wall-climbing robots to protect these human employees from a hazardous environment and occupational injuries. These modern robots can adhere to a surface through the functionalities of suction cups. Implementing suction cups in Robotics is helping robots to reach impossible places efficiently and effectively. Suction cups do not require a vacuum pump or reducing weights and power consumption of robots for specific purposes. Multiple companies are filing for patents in implementing suction cups in robots an actuator can depress the suction cups in a direction of a vertical surface where the outside of the cup is made of a friction coefficient low material that enables the cup to slide. Industries can utilize these wall-climbing robots to detect small stress cracks in the boilers or tanks.

A New Zealand-based Robotics company known as Invert Robotics is developing wall-climbing robots with the help of US$8.8 million financings from an agtech firm Finistere and Yamaha Motor Ventures & Laboratory Silicon Valley. Some researchers and scientists at Zhejiang University, China have developed wall-climbing robots to stand on any kind of surface through a vacuum suction unit. Gecko Robotics is utilizing robots to inspect and detect any thickness, cracks, or other degradations inside tanks, boilers, pipes, and so on with magnetic adhesion. Simon Fraser University in British Columbia utilizes Van der Waals forces for robots to climb walls efficiently with a dry adhesive and a silicon-like polymer that enable adhesion without any chemical or energy.

Researchers Xin Li and Kaige Shi from Zhejiang University have utilized water and centrifugal forces to overcome the surface restrictions with a rotating ring of water. It usually fails to be on the surface due to the flow of air from the atmosphere into a vacuum zone. They have built confined seals to slightly deform and close the gaps between the sealing ring and the texture of the surface. This creates smaller gaps for the flow resistance and gaps in the seals become bigger. The suction cups are dependent on a rotating stream of water to maintain a seal over different surfaces. This will prevent vacuum leakages remove pressure differences in the vacuum zone. The scientists have named this method the Zero Pressure Difference or ZPD. These researchers have tested the new suction cups in robots through three machines spider-man style robot, a wall-climbing robot with ZPD as well as a robotic arm. A whole lot of water was pushed out of these machines when the cups were moving. Each time wall-climbing robots move forward on a wall sufficient water creates a constant flowing seal for suction cups to stick to.

Yes, introducing wall-climbing robots through the implementation of suction cups has revolutionized the way industries clean their boilers, tanks, pipes, and high-walled objects. It has helped Robotics to gain a new perspective on the functionalities of robots.

A California robotics company is about to bring a high-tech knee brace to market that could relieve the suffering of millions of Americans grappling with osteoarthritis of the knee. It may especially appeal to patients who want to avoid knee replacement surgery.

San Francisco-based Roam Robotics said its $7,000 Ascend orthosis should start shipping this winter. Certified by the FDA as a Class 1 medical device, Roamanticipates reimbursement from both Medicare and private insurance. Medicare could cover 50% orhigher, and with private insurance the entire cost could be covered in some cases, Roam says.

Roam Robotics CEO Tim Swift

Roam is located in the San Franciscos Mission district, across the street from Otherlab, an engineering firm awarded tens of millions of dollars in government research contracts, mostly for robotics and energy projects. Roam is one of several start-ups to emerge from Otherlab. Its founder and CEO Tim Swift is a veteran of Ekso Bionics, a pioneer in the exoskeleton field. After working on heavy and super expensive exoskeletons, Swift concluded that a radical departure from conventional designs was necessary if exoskeleton technology was to become accessible and affordable.

I believe that we have the ability to change the relationship that people have with robots on a scale thats really never been considered, says Swift. I dont want people to view robots as something that overtakes what it is to be human. Our goal is not to build cyborgs. Its to make people more human than they ever were.

Ascend is made of lightweight carbon fiber and high-strength woven fabric. The pneumatically powered device is connected to a rechargeable battery carried in a backpack. Sensors in the custom-fitted knee brace provide real-time data to Ascends microprocessors, where proprietary algorithms detect user intent, then extend and flex the knee. Ideally, this relieves pain and increases patients ability to navigate stairs and master previously simple everyday activities.

Ascend is made of lightweight carbon fiber and high-strength woven fabric.

Rowan Paul, a sports medicine doctor who has consulted on Ascend, says it may appeal to those who are reluctant to use a cane because of the stigma of disability it carries. The knee brace makes them look like an athlete with an injury, he says. Ascend could also reduce or eliminate the need for opioid pain meds or cortisone injections, which offer temporary relief for osteoarthritis but come with a risk of side effects.

I have seen several patients, where if we can just give them a little bit of help in a very targeted, precise way, they don't need to do a knee replacement, says Paul.

Roams market research puts the number of patients who are living with severe pain and limited mobility because of osteoarthritis of the knee at 10 million or more.

The pneumatically powered device is connected to a rechargeable battery carried in a backpack.

The company has opened a storefront in San Francisco where patients cantest driveAscend. Reid Weaver drove down from Tacoma, Washington, in June to try one out and was sold on the product. Its so comfortable and its so light, you dont even feel that its there, says Weaver, who spent 19 years as a SWAT police officer in Washington state and now works as a court officer protecting judges in Tacoma.

Weaver had leg surgery after a hiking accident but the surgery exacerbated his osteoarthritis. An avid outdoorsman who played football in college, Weaver, 60, manages to ride a motorcycle to work. With the Ascend knee brace on, Weaver finds he can go up and down stairs with ease and was surprised that it was no longer a struggle to get up from a chair, a challenge for many with osteoarthritis in their knees.

Reid Weaver

This thing was way more powerful than I thought it would be, says Weaver. It basically lifted me out of a sitting position without using my hands, without lurching forward. I think its going to be a game changer.

52-year-old Angelique Newman-Malone of San Jose, California, says she felt trapped in her own body by osteoarthritis. After stumbling upon an ad for Ascend on Facebook, Newman-Malone wore the knee brace on multiple occasions and pronounced it agodsend.

I felt like I had somebody supporting me, like a buddy to walk next to me, she says. That feeling is amazing.

But the best perk for Newman-Malone is that the knee brace allows her to kneel and then get up. A devoutly religious Christian, she said the ability to kneel when she prays is crucial.

Roam has two other smart knee brace models in development. Elevate, Roams knee brace for skiing, was available for renting at ski resorts in the western US for two winter ski seasons but wasnt in use last winter because of the pandemic. Roam COO Nikhil Dhongade says he's hopeful skiers wearing Elevate will be back on the slopes for the 2022-2023 winter season.

Roam has also been developing a smart knee brace for soldiers. Swift says the Armys Special Operations Command has been testing the military model, which is called the Forge.

Roam Robotics Forge

While Elevate and The Forge can be worn on both knees, Ascend has been designed for a single knee because osteoarthritis tends to manifest in one leg initially. Roams Tim Swift notes that more than the 80% of total knee replacements are done on just one leg.

Swift says that as impressive as these high-tech knee braces are now, wait until you see where these wearable robots are heading. To drive home the point, he uses terms associated with aviation and automobiles.

Were not at the end of any runway here, were at the very start, says Swift. What we're building here is much closer to the model T than the Toyota Corolla.

Editors' Note: This story was updated to clarify that Ascend arrives this winter, not fall.

Robotic Brace Could Mean the End of Knee Replacement Surgery for Some - PCMag

Bar Rescue executive producer and host Jon Taffer on why he believes robots can help the restaurant worker shortage.

Bar Rescue executive producer and host Jon Taffer believes technology will solve the worker shortage facing the restaurant industry today.

On FOX Business'"Varney and Co.,"Taffer pointed to his recent visit to a Westin Hotel where his room service waiter was a robot.

"So in a hotel of that size, that eliminates six, seven, eight employees," he said. "We look at cooking technologies, which are now eliminating another one or two employees."

LABOR SHORTAGE MAY GET WORSE BEFORE IMPROVING, NABE SURVEY

The Chamber of Commerce has warned the worker shortage poses the biggest threat to the economy's still-nascent recovery from thecoronaviruspandemic after the government reported that the U.S. had a little more than 9.2 million vacantjobopenings in May, a record-shattering number despite the 9.3 million unemployed Americans.

"Business can't stop," Taffer told hostStuart Varney. "We've got to find solutions. So automation, computerization, robotics -- all of these things are going to play very, very heavily."

JOHNNY ROCKETS, FATBURGER OWNER SAYS LABOR SHORTAGES FACING RESTAURANTS A TOTAL NIGHTMARE

Bar Rescue executive producer and host Jon Taffer weighs in on employee shortages, innovative tech in the restaurant industry, COVID vaccine and mask requirements and his new line of drinks.

Taffer, who has been part of the food industry for decades, said the automation trend gained momentum two and a half years ago when unemployment was so low, businesses had trouble hiring employees then as well.

"Many of us started on this automation path back then, which is really paying off now," he said. "We have 60% less back-of-the-house employees because of technology."

He went on to say this can be beneficial amid the pandemic because every less employee is one less point of contamination.

"When employees don't come back to work, I think many of them are going to find their jobs have been replaced by machines," he said.
