German exoskeleton-maker narrows gap between robots and humans

  • VW considering permanent use after successful field test
  • Plans to launch 'Paexo' upper-body exoskeleton on Thursday

BERLIN: German artificial limb manufacturer Ottobock plans to start selling a mechanical exoskeleton that makes manual labour for factory workers easier this week, joining a field already crowded with major industrial players and start-ups.
The 99-year-old firm, which started out making prosthetics for World War One veterans, is seeking to tap new growth opportunities ahead of a possible stock market listing.
The family-owned company has tested the 'Paexo', a wearable upper-body exoskeleton designed to ease the physical strain of repetitive overhead assembly work, on 30 workers at a Volkswagen plant in Bratislava.
After 80 percent of workers said they would recommend it to colleagues, Ottobock is talking to Volkswagen about using the Paexo in series production, said Soenke Roessing, head of Ottobock's Industrials unit.
VW said it was in final consultations about rolling out the exoskeleton in series production.
Exoskeletons were developed for medical and military use. But as workers age, sales of exoskeletons for industry are forecast to rise to $1.76 billion in 2028 from $67.29 million this year, according Rian Whitton, an analyst at technology market intelligence firm ABI Research.
This corresponds to more than 126,000 units in 2028, against around 3,900 this year, as companies seek to make workers more productive and protect them from injury.
Ottobock plans to launch the Paexo on Thursday. Beyond the automotive sector, it is targeting the aerospace, shipping and construction industries as well as tradespeople, and is running pilots at over 20 sites in Europe, Roessing said.
Hans Georg Naeder, grandson of Ottobock's founder, sold a 20 percent stake to Swedish private equity firm EQT last year aiming to increase the company's value ahead of a possible IPO.
Since then, Ottobock, which had sales of 927.4 million euros ($1.08 billion) in 2017, has revamped its management with Naeder appointing Oliver Scheel as CEO, the first non-family member to run the company.
Ottobock began by developing exoskeletons to help people with partial paralysis or spinal injury walk again. Its move into industry is part of a broader bet on bionics - using mechanics to augment human strength.
It will not be alone. A host of new start-ups, including Dutch firm Laevo and California's SuitX, are racing more established players in the defence and engineering space, such as Lockheed Martin and Panasonic.
Ottobock's closest competitor, Iceland's Ossur, has teamed up with Fiat Chrysler's robotics specialist Comau and plans to launch an upper-body exoskeleton in December.
Other car companies are testing the technology too.
Ford Motor Co started testing upper-body skeletons developed by Ekso Bionics Holdings at two U.S. factories last year. Meanwhile workers at BMW's Spartanburg factory in the United States have trialed an exoskeleton vest from Levitate Technologies.
Audi is rolling out a "Chairless Chair" exoskeleton made by Swiss start-up Noonee that allows workers to sit instead of standing at its Ingolstadt factory.
It has also tested upper-body exoskeletons from Laevo and is planning a comparative study with Ottobock's Paexo and Levitate's Airframe later this year.
Patrick Schwarzkopf, managing director of the VDMA Robotics + Automation Association, said the scramble to develop exoskeletons underscored a trend towards closer interaction between humans and machines in factories.
"An exoskeleton is probably the most intense form of human-robot collaboration. In a way, your arm becomes a robot arm because it has reinforced strength," he said.
Schwarzkopf sees exoskeletons competing with inexpensive collaborative robots, or "cobots", which can work alongside humans, for example placing a tyre on a vehicle while leaving the worker to screw it into place.
A cobot can cost as little as $10,000, although they typically cost two to three times that. Ottobock's Paexo is priced at 5,000 euros.
The Paexo is a 'passive' exoskeleton that works by transferring the weight of the raised arms to the hips through a mechanical cable technology that takes the stress off a worker's shoulders.
The backpack weighs 1.9 kilograms and gives the user's arms a feeling of weightlessness akin to floating in a swimming pool.
Roessing said the Paexo was the lightest of its kind and can be worn for eight-hour shifts, allowing workers to hold heavy tools or screw in parts overhead without strain. To make his point, he wore the Paexo throughout an interview with Reuters.
Juergen Klippert, an expert on the future of work at the IG Metall union, said exoskeletons ostensibly provided relief. But it was unclear whether a worker's joints would be burdened by holding heavy tools for prolonged periods.
Ottobock plans to make its exoskeletons "intelligent" by adding sensors to help workers correct their posture and tell them what part to place where in the assembly process. Prototypes to support the back and hand are also in development.
After colleagues kept asking to borrow the 'Paexo' for the weekend to do home renovations, Roessing now wants to launch a simplified version for the price of a good power tool.


Saudi Arabia and UAE launch a new joint cryptocurrency

Saudi Arabia and UAE launch a new joint cryptocurrency

  • The cryptocurrency will be limited to banks during its first stages
  • The program will also help the two countries evaluate the monetary policies of a centralized currency

Saudi Arabia and the UAE have launched a joint cryptocurrency during the first meeting of the Saudi-Emirati Coordination council Saturday in Abu Dhabi, UAE’s national press agency WAM said.

The cryptocurrency will be limited to banks during its first stages, until the governments have a better understanding of how Blockchain technology operates cross-borders.

The currency operates on the use of a “distributed database between the central banks and the participating banks from both sides,” aiming to protect customer interests, set technology standards and assess cybersecurity risks. The new program will also help evaluate the impacts of a central currency on monetary policies.

During the meeting, representatives of Saudi Arabia and the UAE also signed the Joint Supply Chained Security Cooperation program, which tests the two countries abilities to provide vital supplies during times of crisis and national emergencies, as well as share expertise and knowledge in the field.

All 16 members of the executive committee of the council followed up on the execution of the initiatives mentioned in the Strategy of Resolve.

Representatives also set five other initiatives to enhance the cooperation between the two countries, such as facilitating the traffic between ports, improving airports to make it easier for people with disabilities to travel, creating a financial awareness program for children aged 7-18, starting a joint platform to support local SMEs, and the integration of civil aviation markets,

The committee was headed by Mohammad bin Abdullah Al-Gergawi, minister of cabinet of affairs and the future of UAE, and Mohammed bin Mazyad Al-Twaijri, minister of economy and planning in Saudi. The committee will also monitor the implementation of the initiatives.
