#430652 The Jobs AI Will Take Over First
11th July 2017: The robotic revolution is set to cause the biggest transformation in the world’s workforce since the industrial revolution. In fact, research suggests that over 30% of jobs in Britain are under threat from breakthroughs in artificial intelligence (AI) technology.
With pioneering advances in technology many jobs that weren’t considered ripe for automation suddenly are. RS Components have used PWC Data to reveal how many jobs per sector are at risk of being taken by robots by 2030, a mere 13 years away. Did you think you were exempt from the robot revolution?
The top three sectors who are most exposed to the threats of robots are Transport and Storage, Manufacturing and Wholesale and Retail with 56%, 46% and 44% risk of automation respectively. The PWC report states that the differentiating factor between losing jobs to automation probability is education; those with a GCSE-level education or lower face a 46% risk, whilst those with undergraduate degrees or higher face a 12% risk. If a job is repetitive, physical and requires minimum effort to train for, this will have a higher likelihood to become automated by machines.
The manufacturing industry has the 3rd highest likelihood potential at 46.6%, shortly behind Transportation and Storage (56.4%) and Water, Sewage and Waste Management (62.6%). Although the manufacturing sector has the 3rd highest likelihood, it has the second largest number of jobs at risk of being taken by robots; an astonishing 1.22 million jobs are at risk in the near future. Repetitive manual labour and routine tasks can be taught to fixed machines and mimicked easily, saving employers both time and money.
The three sectors least at risk are Education, Health and Social and Agriculture, Forestry and Fishing with 9%, 17% and 19% risk of automation respectively. These operations are non-repetitive and consist of characteristics that cannot be taught and are harder to replicate with AI and robotics.
These are not the only fields where the introduction of AI will have an impact on employment prospects; Administrative and Support Services, Accommodation and Food Services, Finance and Insurance, Construction, Real Estate, Public Administration and Defence, and Arts and Entertainment are not out of the woods either.
The future is not all doom and gloom. Automation is set to boost productivity to enable workers to focus on higher value, more rewarding jobs; leaving repetitive and uncomplicated ones to the robots. An increase in sectors that are less easy to automate is also expected due to lower running costs. Wealth and spending will also be boosted by the initiation of AI seizing work. Also, there are just some things AI cannot learn so these jobs will be safe.
In some sectors half of the jobs could be taken by a fully automated system. Is your job next?

Spherical Induction Motor Eliminates Robot’s Mechanical Drive System
PITTSBURGH— More than a decade ago, Ralph Hollis invented the ballbot, an elegantly simple robot whose tall, thin body glides atop a sphere slightly smaller than a bowling ball. The latest version, called SIMbot, has an equally elegant motor with just one moving part: the ball.
The only other active moving part of the robot is the body itself.
The spherical induction motor (SIM) invented by Hollis, a research professor in Carnegie Mellon University’s Robotics Institute, and Masaaki Kumagai, a professor of engineering at Tohoku Gakuin University in Tagajo, Japan, eliminates the mechanical drive systems that each used on previous ballbots. Because of this extreme mechanical simplicity, SIMbot requires less routine maintenance and is less likely to suffer mechanical failures.
The new motor can move the ball in any direction using only electronic controls. These movements keep SIMbot’s body balanced atop the ball.
Early comparisons between SIMbot and a mechanically driven ballbot suggest the new robot is capable of similar speed — about 1.9 meters per second, or the equivalent of a very fast walk — but is not yet as efficient, said Greg Seyfarth, a former member of Hollis’ lab who recently completed his master’s degree in robotics.
Induction motors are nothing new; they use magnetic fields to induce electric current in the motor’s rotor, rather than through an electrical connection. What is new here is that the rotor is spherical and, thanks to some fancy math and advanced software, can move in any combination of three axes, giving it omnidirectional capability. In contrast to other attempts to build a SIM, the design by Hollis and Kumagai enables the ball to turn all the way around, not just move back and forth a few degrees.
Though Hollis said it is too soon to compare the cost of the experimental motor with conventional motors, he said long-range trends favor the technologies at its heart.
“This motor relies on a lot of electronics and software,” he explained. “Electronics and software are getting cheaper. Mechanical systems are not getting cheaper, or at least not as fast as electronics and software are.”
SIMbot’s mechanical simplicity is a significant advance for ballbots, a type of robot that Hollis maintains is ideally suited for working with people in human environments. Because the robot’s body dynamically balances atop the motor’s ball, a ballbot can be as tall as a person, but remain thin enough to move through doorways and in between furniture. This type of robot is inherently compliant, so people can simply push it out of the way when necessary. Ballbots also can perform tasks such as helping a person out of a chair, helping to carry parcels and physically guiding a person.
Until now, moving the ball to maintain the robot’s balance has relied on mechanical means. Hollis’ ballbots, for instance, have used an “inverse mouse ball” method, in which four motors actuate rollers that press against the ball so that it can move in any direction across a floor, while a fifth motor controls the yaw motion of the robot itself.
“But the belts that drive the rollers wear out and need to be replaced,” said Michael Shomin, a Ph.D. student in robotics. “And when the belts are replaced, the system needs to be recalibrated.” He said the new motor’s solid-state system would eliminate that time-consuming process.
The rotor of the spherical induction motor is a precisely machined hollow iron ball with a copper shell. Current is induced in the ball with six laminated steel stators, each with three-phase wire windings. The stators are positioned just next to the ball and are oriented slightly off vertical.
The six stators generate travelling magnetic waves in the ball, causing the ball to move in the direction of the wave. The direction of the magnetic waves can be steered by altering the currents in the stators.
Hollis and Kumagai jointly designed the motor. Ankit Bhatia, a Ph.D. student in robotics, and Olaf Sassnick, a visiting scientist from Salzburg University of Applied Sciences, adapted it for use in ballbots.
Getting rid of the mechanical drive eliminates a lot of the friction of previous ballbot models, but virtually all friction could be eliminated by eventually installing an air bearing, Hollis said. The robot body would then be separated from the motor ball with a cushion of air, rather than passive rollers.
“Even without optimizing the motor’s performance, SIMbot has demonstrated impressive performance,” Hollis said. “We expect SIMbot technology will make ballbots more accessible and more practical for wide adoption.”
The National Science Foundation and, in Japan, Grants-in-Aid for Scientific Research (KAKENHI) supported this research. A report on the work was presented at the May IEEE International Conference on Robotics and Automation in Stockholm, Sweden.
