How You Can Put A Robotic Arm To Use
The robotic arm is an extraordinary multi-functional invention used industrially and medically. The robotic system may be used to accomplish undesirable tasks in the workplace, freeing up more creative and fulfilling positions. Or the robotic arms can be used in stroke therapy, in surgery and to assist paralyzed patients. Who knows where the future of this technology will take us?
Starting in 1975, robotic arms have been used for industrial purposes. In some cases, they do the work more quickly, more accurately and more efficiently than human workers ever could. Yet in other instances, they simply perform work that is too monotonous, dangerous or undesirable for men and women. In the US auto industry, for example, there is one robotic arm for every ten workers. Industrial robots lift heavy objects, handle chemicals, and paint and assemble parts. Rather than replace jobs, the robotic system is intended to free up more creative, fulfilling work for people instead. After all, the Czech word “robota” translates to “drudgery work.”
Using a modified robotic arm, Dr. Alon Wolf and Dr. Howie Choset have developed a machine that can perform minimally-invasive surgery with great accuracy. The invention is called the “CardioARM” and has been designed for abdominal surgery, heart bypass surgery and mouth surgery, but can also be used to perform a laparoscopy, colonoscopy, and arthroscopy. The CardioARM is operated by a joystick and can navigate through the body to the problem areas. The flexible tele-operated probe is programmed to remember pathways and it can take tools into regions that surgeons would otherwise have to slice into. “Tools in operation rooms are not flexible. The CardioARM is flexible enough for remote and hard to reach anatomies,” explains Dr. Wolf. “The heart is a good example… now we don’t have to cut the person open.”
A new report found that two monkeys containing tiny electrodes attached to their brains could control a robotic arm using their thoughts. First researchers used the computer to teach the monkeys to move the arm and soon the monkeys were reaching for food and grabbing it, reaching their mouths two-thirds of the time. “In the real world, things don’t work as expected,” said Dr. Andrew Schwartz, a professor of neurobiology at the University of Pittsburgh. “The marshmallow sticks to your hand or the food slips, and you can’t program a computer to anticipate all of that. But the monkeys’ brains adjusted. They were licking the marshmallow off the prosthetic gripper, pushing food into their mouth, as if it were their own hand.” This exciting new robot research promises to help paralyzed patients.
