#428802 New AI Mental Health Tools Beat Human ...
About 20 percent of youth in the United States live with a mental health condition, according to the National Institute of Mental Health. That’s the bad news. The good news is that mental health professionals have smarter tools than ever before, with artificial intelligence-related technology coming to the forefront to help diagnose patients, often with much greater accuracy than humans. A new study published in the journal Suicide and Life-Threatening Behavior, for example, showed that… read more Continue reading

#428181 Adding social touch to robotics
A squeeze in the arm, a pat on the shoulder, or a slap in the face – touch is an important part of the social interaction between people. Social touch, however, is a relatively unknown field when it comes to robots, even though robots operate with increasing frequency in society at large, rather than just in the controlled environment of a factory. Merel Jung is conducting research at the University of Twente CTIT research institute into social touch interaction with robots. Using a relatively simple system – a mannequin's arm with pressure sensors, connected to a computer – she has succeeded in getting it to recognize sixty percent of all touches. The research is being published today in the Journal on Multimodal User Interfaces scientific journal. Continue reading

ST Kinetics, the Title Sponsor for the inaugural edition of the event, is one of the key exhibitors, together with other leading industry players such as ABB, Murata, Panasonic, SICK Pte Ltd, and Tech Avenue amongst others. Emerging SMEs such as H3 Dynamics, Design Tech Technologies and SMP Robotics Singapore will also showcase their innovations at the exhibition. Participating research institute, A*STAR’s SIMTech, and other IHLs supporting the event include Ngee Ann Polytechnic, Republic Polytechnic and the Institute of Technical Education (ITE).
Visitors will also be able to view “live” demonstrations at the Demo Zone and come up close with the latest innovations and technologies. Some of the key highlights at the zone includes the world’s only fully autonomous outdoor security robot developed by SMP Robotics Singapore, as well as ABB’s Yumi, IRB 14000, a collaborative robot designed to work in close collaboration and proximity with humans safely. Dynamic Stabilization Systems, SIMTech and Design Tech will also be demonstrating the capabilities of their robotic innovations at the zone.
At the Singapore International Robo Convention, key speakers representing regulators, industry leaders and academia will come together, exchange insights and engage in discourse to address the various aspects of robotic and automation technology, industry trends and case studies of robotics solutions. There will also be a session discussing the details of the Singapore National Robotics Programme led by Mr Haryanto Tan, Head, Precision Engineering Cluster Group, EDB Singapore.
SIRE will also host the France-Singapore Innovation Days in collaboration with Business France, the national agency supporting the international development of the French economy. The organisation will lead a delegation of 20 key French companies to explore business and networking opportunities with Singapore firms, and conduct specialized workshops.
To further foster a deeper appreciation and to inspire the next generation of robotics and automation experts, the event will also host students from higher institutes of learning on Education Day on 2 November. Students will be able to immerse themselves in the exciting developments of the robotics industry and get a sampling of how robotics can be applied to real-world settings by visiting the exhibits and interacting with representatives from participating companies.
Mr Leck Chet Lam, Managing Director, Experia Events, says, “SIRE will be a game changer for the industry. We are expecting the industry’s best and new-to-market players to showcase their innovations, which could potentially add value to the operations across a wide spectrum of industry sectors, from manufacturing to retail and service, and healthcare. We also hope to inspire the robotics and automation experts of tomorrow with our Education Day programme.
Experia Events prides itself as a company that organises strategic events for the global stage, featuring thought leaders and working with the industries’ best. It is an honour for us to be partnering SIAA, a recognised body and key player in the robotics industry. We are privileged to be able to help elevate Singapore’s robotics industry through SIRE and are pulling out all stops to ensure that the event will be a resounding success.”
SIRE is supported by Strategic Partner, IE Singapore as well as agencies including EDB Singapore, GovTech Singapore, InfoComm Media Development Authority, A*STAR’s SIMTech, and Spring Singapore.

#428053 Omnidirectional Mobile Robot Has Just ...
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.
