Robots are one of the most popular visions of the future, evident in many science fiction novels, from Isaac Asimov’s “I Robot” to Douglas Adam’s “Hitchhiker’s Guide to the Galaxy.” Often humankind fears that robotics technology could get so advanced that these cybernetic organisms will begin thinking and acting for themselves, with little regard for human hierarchy. However, the robots we use today are quite harmless and perform a number of useful functions.
Scientists are looking at how robots may function medically to help people live longer, more productive lives. For instance, researchers found that test monkeys can move a robotic hand simply by using their minds. That hand can wave, peel a banana and pick up items, just by reading the brain’s electrical output. Doctors say medical robots can help stroke victims or paraplegics accomplish everyday tasks. Currently, electronic wheelchairs can maneuver and computers can type based on one’s thoughts. Dr. Bruce Volpe of the Burke Medical Research Institute is developing a “robotic therapist,” which will help stroke patients perform arm exercises. “By improving movement in the shoulder and upper arm, patients can do simple things like push objects across a table, use a computer mouse or write,” he explains.
There has always been some fear that robots may steal our jobs. Currently, in the car industry, there is one robot worker for every ten in Italy, Japan and Germany. However, for a graying workforce, like in Japan, robots may be needed to fill some of the gaps. Since the workforce is expected to shrink 16% by 2030, a think tank estimated that robots could help fill 3.5 million jobs, freeing up time for people to focus on more meaningful tasks. Robots can vacuum office buildings, mow lawns, monitor their owner’s health, baby-sit children and read books aloud. According to Tech Digest, intelligent robots may one day be firefighting, cleaning hospital rooms, picking up trash on sidewalks, cleaning nuclear spills, clearing landmines, disassembling bombs, fighting wars, teaching children and guarding homes.
Robotics technology is rapidly advancing. The robot can follow commands as well as it can follow its master. It can perform drone-like tasks but can also adapt to new situations. Humanoid robots can display emotions and teach us more about how our own brains work. While many people fear that humans and robots cannot peacefully coexist, it seems this breakthrough technology can make life much easier and more enjoyable, if we can afford it.
