The technique is being called "a vision of eye surgery in the future." The technique is being called "a vision of eye surgery in the future." air009/Shutterstock In a medical first, surgeons have used a robot to operate inside the human eye, greatly improving the accuracy of a delicate surgery to remove fine membrane growth on the retina. Such growth distorts vision and, if left unchecked, can lead to blindness in the affected eye. Currently, doctors perform this common eye surgery without robots. But given the delicate nature of the retina and the narrowness of the opening in which to operate, even highly skilled surgeons can cut too deeply and cause small amounts of hemorrhaging and scarring, potentially leading to other forms of visual impairment, according to the researchers who tested out the new robotic surgery in a small trial. The pulsing of blood through the surgeon's hands is enough to affect the accuracy of the cut, the researchers said. In the trial, at a hospital in the United Kingdom, surgeons performed the membrane-removal surgery on 12 patients; six of those patients underwent the traditional procedure, and six underwent the new robotic technique. Those patients in the robot group experienced significantly fewer hemorrhages and less damage to the retina, the findings showed. Continue reading

Over the last year, FedEx has been working with Savioke, a Silicon Valley company that makes autonomous indoor delivery robots, to develop a robot delivery system for its repair facility in Collierville, Tennessee. The bots are used by workers to move items around the office, cutting down on wasted time, and storage space, as workers no longer have to spend time walking around picking up and dropping off items, or need a mailroom clerk to do it for them. Savioke has spent the last few years building its Relay robot, a stout trashcan-height bot that can autonomously ferry about 10 pounds of goods around. The robot combines a range of technologies to see and navigate the world on its own, including lidar (the laser radar technologies powering the eyes of self-driving cars) and depth-sensing 3D vision cameras (similar to those found in a Microsoft Kinect). The company has been building relationships with hotels to use Relays as replacements for the menial tasks done by concierge and other hotel staff. Instead of a worker delivering room service or a toothbrush, hotels can now press a button on a tablet, have a Relay come to them, load it up, and send it to a guest, freeing up their time to do more important tasks. Hotels need to install a wireless system in their elevators so that Relays can open the doors on their own. The bots, which can be rented from Savioke for $2,000 a month, can navigate through areas that have been mapped, even if there are new obstacles, such as chairs that have been moved around, or people. Relays have completed over 100,000 autonomous deliveries at a range of hotels owned by Sheraton, Aloft, Holiday Inn, Westin, and others. The robots make little beeps as they carry out their errands, and the touchscreen on their fronts tell passersby what they’re up to as they’re out. When they show up to a guest’s door, they open their cargo door, say hello on the screen, and let the guests interact by pushing a few buttons to say whether they were happy with their delivery. Savioke’s robots have also started popping up at a few other office facilities around the US: Continue reading
