Trends and Innovations: Robots
In the late 15th century, Leonardo da Vinci
sketched a plan for a “mechanical knight” that could sit, stand, and move its
arms. Powered by pulleys and levers,
it’s often regarded as the earliest know example of robot design. Now many robots are found in hospitals. A surgical robot called the da Vinci performs
minimally invasive surgery and has been involved in over 1.5 million
procedures.
