While some robots 1 (intend) to assist humans, robotics can also reproduce realistic limb-like functions for those that have lost arms, legs and other parts of their bodies. These prosthetics (义肢) have existed in one form or another 2 at least ancient Egyptian times. Early limb replacements involved 3 (use) materials such as wood or leather for support and balance. In the 1960s, the capabilities of prosthetics to enhance lives were explored. This included incorporating lightweight carbon-fibre material into prosthetics 4 amputees (截肢者) could partake and succeed in sporting activities.
However, it wasn’t until 1986 that electronic prosthetic limbs 5 (explore). Scottish inventor David Gow began his mission to make existing pneumatic(充气的) arms easier to use, lighter in weight and more functional. This led to the first bionic (仿生的) arm being ready for use in 1998. The first user of this bionic arm was a man named Campbell Aird, who lost his arm 6 cancer. After experiencing the benefits of an electrically powered, lightweight limb, Aird said at the time: “For the first time in 16 years I 7 (reach) above my head to pick a book off a shelf. It was a great moment for me.
Today, pioneering work in robotics is allowing 8 who are missing a limb to explore the world with better balance, accuracy, precision, speed and in some cases, even touch. 9 new competitive event called the Cybathlon has been established to compare the speed, skills and efficiency of robotic limbs. The “arm prosthesis race” is designed to rank new robotic arms in sensory feedback, palm rotation ability and coordination in handling objects of different sizes, shapes and weights. Twenty countries partake in this event, 10 (far) driving the innovation of life-changing technology.
