“Please leave the room, close the door and start a disinfection,” a robot says in a mock-hospital ward in Denmark. The robot then crisscrosses the room and zaps microbes with beams of ultraviolet light.

The Shropshire Star reports that Blue Ocean Robotics, the company that makes the devices, claims the robots can kill 99.99 percent of all germs in a hospital ward in 10 minutes. Demand has surged since the outbreak of COVID-19.

The pandemic has led to autonomous disinfection becoming a rapidly emerging trend in health care. Denmark’s UVD Robots shipped hundreds of the robots to China in February, hundreds more throughout Europe in March, and several hundred more were headed to the United States.

Wyn Griffiths’ wife went to a hospital recently and realized that even though she frequently washed her hands, there was no way to avoid touching door handles. So Griffiths, from Wales, UK, designed a hands-free door handle that allows people to open doors using only their arms.

The design can be easily attached to any existing door handle. The file for printing this device is available online and can be downloaded for free at grabcad.com/library/coronavirus-covid-19-hands-free-forearm-door-pull-1

Griffith said he hopes people with access to a 3D printer can help hospitals or any public sites by making and distributing these.

A Minnesota man invented a device to ease the process of picking a golf ball out of a cup. Now his invention has been modified as the Covid Cup.

Falcon golf founder Evan Johnson’s invented the device. After sinking a putt, the golfer takes the putter, sets the shaft below the clip, and raises the flagstick attachment using the putter to about waist height. There is no need for human contact with the flagstick.
