Hospitals around the world are turning to robots to cope with rising patient numbers and staff shortages. What used to sound like science fiction, a machine rolling down a corridor to deliver medicine or a robotic arm assisting in surgery, is now part of daily hospital routine in many countries. Hospital administrators say robots do not replace nurses and doctors; instead, they take over repetitive or physically demanding tasks so that medical staff can spend more time with patients.

The most common type is the delivery robot, a small wheeled machine that carries meals, linen and medical supplies between departments. These robots use sensors and floor maps to navigate crowded hallways, stopping automatically when a person or trolley blocks their path. Because a single robot can complete dozens of delivery runs a night without needing rest, hospitals that use them report that nurses save several hours of walking each shift, time they can then devote directly to patients. Some hospitals have even trained delivery robots to call the lift and hold doors open using a wireless signal.

Surgical robots represent a more advanced use of the technology. Guided by a surgeon sitting at a control console, robotic arms can make smaller, steadier movements than the human hand, which reduces bleeding and shortens recovery time for patients. Surgeons who have used these systems say the robots also allow them to operate through much smaller cuts, so patients often leave hospital days earlier than they would after traditional surgery. However, the robot only carries out the movements the surgeon directs; it has no ability to plan or perform an operation on its own.

Despite these advances, doctors are quick to point out that hospital robots still depend heavily on human judgement. A robot can be reprogrammed to handle a new task, but it cannot read a patient's expression, notice a subtle change in symptoms, or comfort a frightened family member the way a nurse can. For this reason, most hospitals see robots as assistants that free up staff time, not as a workforce that will one day replace the people who currently do the work.

A team of transport historians recently reviewed patent records, newspaper archives and museum collections to trace how the modern bicycle came into being. Their research shows that the machine familiar today evolved gradually over almost a century, through a series of small but crucial improvements rather than a single flash of invention. The earliest ancestor, a wooden, two-wheeled device called the draisine, was patented by the German inventor Karl Drais in 1817. Riders pushed it along with their feet, since it had no pedals, and it was used mainly as a novelty for wealthy young men in city parks.

Pedals were not added to the front wheel until the 1860s, producing a machine nicknamed the boneshaker because of its rigid iron frame and wooden wheels. [I] Engineers then discovered that a larger front wheel let a rider travel farther with each turn of the pedals, which led to the tall, dramatic high-wheel bicycle known as the penny-farthing. [II] Mounting a penny-farthing required real skill and no small amount of courage, since a sudden stop could throw the rider head-first onto the road. [III] Despite the danger, the design remained popular throughout the 1870s because no faster alternative existed. [IV]

The real breakthrough, researchers found, came in 1885 with John Kemp Starley's Rover safety bicycle, which used a chain drive to a rear wheel of the same size as the front. This single design change made cycling dramatically safer and easier to balance, and within a decade it had replaced the penny-farthing almost everywhere the bicycle was sold. Because riders no longer needed unusual strength or balance to climb aboard, the safety bicycle opened cycling to a far wider public, including women, who had largely been excluded from the earlier, more dangerous designs.

The spread of the safety bicycle had effects that reached well beyond transport. Historians note that for many women in the 1890s, the bicycle offered a new and unprecedented degree of independence, letting them travel to work, visit friends or run errands without waiting for a chaperone or a carriage. Working-class riders benefited too: a bicycle cost far less than a horse and allowed factory workers to live farther from their jobs, widening the area from which a city could draw its workforce. Some social commentators of the era even credited the bicycle with hastening changes in women's clothing, since long skirts and tight corsets were simply impractical for pedalling.

The researchers conclude that although today's bicycles use lighter materials and, increasingly, electric motors, the basic frame that made cycling safe and practical, two equal wheels driven by a pedal-powered chain, has barely changed since 1885. In their view, the modern e-bike is best understood not as a break from this history but as the latest step in the same long process of small, practical improvements that began with Karl Drais and his wooden draisine two centuries ago.

Some social commentators of the era even credited the bicycle with hastening changes in women's clothing, since long skirts and tight corsets were simply impractical for pedalling.

The researchers conclude that although today's bicycles use lighter materials and, increasingly, electric motors, the basic frame that made cycling safe and practical, two equal wheels driven by a pedal-powered chain, has barely changed since 1885. In their view, the modern e-bike is best understood not as a break from this history but as the latest step in the same long process of small, practical improvements that began with Karl Drais and his wooden draisine two centuries ago.

A team of transport historians recently reviewed patent records, newspaper archives and museum collections to trace how the modern bicycle came into being. Their research shows that the machine familiar today evolved gradually over almost a century, through a series of small but crucial improvements rather than a single flash of invention. The earliest ancestor, a wooden, two-wheeled device called the draisine, was patented by the German inventor Karl Drais in 1817. Riders pushed it along with their feet, since it had no pedals, and it was used mainly as a novelty for wealthy young men in city parks.

Pedals were not added to the front wheel until the 1860s, producing a machine nicknamed the boneshaker because of its rigid iron frame and wooden wheels. [I] Engineers then discovered that a larger front wheel let a rider travel farther with each turn of the pedals, which led to the tall, dramatic high-wheel bicycle known as the penny-farthing. [II] Mounting a penny-farthing required real skill and no small amount of courage, since a sudden stop could throw the rider head-first onto the road. [III] Despite the danger, the design remained popular throughout the 1870s because no faster alternative existed. [IV]

The real breakthrough, researchers found, came in 1885 with John Kemp Starley's Rover safety bicycle, which used a chain drive to a rear wheel of the same size as the front. This single design change made cycling dramatically safer and easier to balance, and within a decade it had replaced the penny-farthing almost everywhere the bicycle was sold. Because riders no longer needed unusual strength or balance to climb aboard, the safety bicycle opened cycling to a far wider public, including women, who had largely been excluded from the earlier, more dangerous designs.

The spread of the safety bicycle had effects that reached well beyond transport. Historians note that for many women in the 1890s, the bicycle offered a new and unprecedented degree of independence, letting them travel to work, visit friends or run errands without waiting for a chaperone or a carriage. Working-class riders benefited too: a bicycle cost far less than a horse and allowed factory workers to live farther from their jobs, widening the area from which a city could draw its workforce. Some social commentators of the era even credited the bicycle with hastening changes in women's clothing, since long skirts and tight corsets were simply impractical for pedalling.
