Tech-Link Healthcare Systems partners with Blue Ocean Robotics Introducing UV-Disinfection Robot
Singapore, 1 November 2016 – The rise of robots have steered Tech-Link Healthcare Systems, a design and integrator of healthcare automation systems to offer solutions beyond automated storage and material handling systems. With a vision of providing holistic solutions for healthcare organisations, Tech-Link extends its capabilities by offering UV disinfection robot solutions via a strategic partnership with Danish robotics company, Blue Ocean Robotics to battle against Hospital Acquired Infections (HAIs).Singapore’s labour intensive healthcare environment and the unknown impact of HAIs in the developed city-state had beckoned Tech-Link Healthcare Systems to offer solutions in the area of disinfection. We recognised the rise in demand for robots to collaborate with humans and have identified this need for customers. Introducing robotic technologies as part of our suite of solutions is the company’s mission to innovate the way healthcare organisations work and enhance their customers’ experience.Tech-Link’s partnership with Blue Ocean Robotics affirms both companies’ efforts in reaching out to new markets with technology and solutions to ease manpower crunch, deliver greater value and improve the quality of healthcare services. As an official sales partner, we bring together Blue Ocean Robotics’ expertise in automating disinfection procedures to promote safer, efficient and more productive work environment.
“Tech-Link looks forward to developing reliable healthcare solutions with hardware and latest technologies from Blue Ocean Robotics for our customers in Singapore and abroad.” said Director of Tech-Link Healthcare Systems, Tan Hock Seng. “Our similar beliefs in the Blue Ocean strategy synergise the collaboration to improve the quality of healthcare services through robotics.” he added.“We are very excited about our new sales partner Tech-Link Healthcare Systems, since it is of great importance for Blue Ocean Robotics to expand our sales of new technologies beyond Denmark’s borders. Blue Ocean Robotics focuses on creating new markets for robots. This includes both the development of new technologies and the creation of new markets for revolutionary robot solutions. We welcome Tech-Link Healthcare Systems with open arms and look forward to a fruitful collaboration in the years ahead.” said Claus Risager, Rune K. Larsen & John Erland Østergaard, Partners and Co-CEOs, Blue Ocean Robotics.
UV-Disinfection RobotThe UV-Disinfection Robot – also called UV-DR – is an autonomous disinfection robot for hospitals, production lines and pharmaceutical companies. The robot is used primarily in, but not limited to the cleaning cycle with the aim of reducing spread of HAIs, infectious diseases, viruses, bacteria and other types or harmful organic materials.UV-DR is a mobile robot that can drive autonomously while emitting concentrated UV-C light onto pre-defined infectious hotspots in patient rooms and other hospital environments, thus disinfecting and killing bacteria and virus on all exposed surfaces. An exposure time of ten minutes is estimated to kill up to 99% of bacteria such as Clostridium Difficile.

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.
