Medical robots and robotics in health care - are they the future? From artificial intelligence-based diagnostics to a Japanese care robot. Learn how robots are becoming ubiquitous in 21st century medicine. Medical robots are on their way to changing healthcare. Edge Medical Robotics, a Chinese company founded just three years ago, recently announced the completion of a $92 million Series B funding round. The company is relying on a world-class team of experts from MIT, Harvard and Imperial College to revolutionize laparoscopic surgery. The global market for medical robots is expected to reach $25 billion in 2025. That's an impressive increase from $5.5 billion in 2018. Surgical robots are just one component of the robotic revolution in healthcare. Hospital robots, nursing robots are also part of the ongoing robotic revolution in healthcare. Soon they will be ubiquitous components involved in the future of health care. When we think of robotics in health care, the first area that comes to mind is robotic surgery. A surgeon will remotely operate robotic arms and surgical instruments while simultaneously observing the operating field through high-definition cameras. Compared to traditional methods, only a couple of incisions are made to allow the instruments, camera and light to pass through the abdomen. Laparoscopic or minimally invasive surgery greatly reduces complications, postoperative pain and leaves only small scars. iData Research estimates that by 2025, the number of robotic-assisted surgical procedures will more than triple to 3 million. Hospital robots are a different breed; they aim to make life easier for nurses, doctors, and ultimately provide better care for patients. ABB, one of the leaders in robotic arms, recently introduced a robot in Shanghai that will take care of medication dispensing in hospitals, avoiding errors and improving efficiency. These tireless assistants can perform many tasks, from automatically disinfecting wards or corridors to delivering medications and even transporting patients, like Robear, Japan's porter. Robear is an interesting example of how Japan is looking to use robots to compensate for a shortage of caregivers and an ever-aging population. Developed by the RIKEN-SRK Center for Human-Interactive Robot Research Collaboration, the robotic caregiver is equipped with numerous sensors and actuators that allow it to lift patients out of bed. This task may seem simple, but it is a major cause of low back pain for caregivers, who often lift patients more than 40 times a day. Thanks to its capacitive tactile sensors, the Smart Rubber Robear does its job conscientiously and without risk to patients. The Japanese company Cyberdyne has also developed exoskeletons that attach to the waist and leg and automatically help lift heavy objects or patients. The device works like a miracle, but is of course designed for slender Japanese sizes. The world is getting older every day. In Japan alone, 28.7% of the population is over the age of 65. That's almost 40 million people. According to a United Nations report, by 2050, one in four people in Europe and North America will be over 65. Japan is at the forefront of this aging crisis. New companion robots have been developed to help with daily tasks and reduce isolation and depression in people with dementia. The potential of these robots, which have only one drawback: their price! They all cost thousands of dollars, but when you consider that pets spend an average of $500 a year, they can be considered quite a worthy long-term investment. There is no doubt that robotic technology is the future of health care. In hospitals, repetitive tasks such as disinfecting rooms, dispensing medication, or helping to care for patients are also great for robots. Finally, therapeutic robots have a great future. In a world suffering from loneliness, intelligent cybernetic devices built with artificial intelligence will provide an aging world with companionship and joy.
