Murderers in early 19th-Century London sometimes tried to kill themselves before they were hanged. Failing that, they asked friends to give their legs a good, hard pull as they dangled from the gallows to ensure their death. Their freshly hanged bodies, they knew, would be handed to scientists for anatomical studies. They didn't want to survive the hanging and regain consciousness while being dissected. If George Foster, executed in 1803, had woken up on the lab table, it would have been in particularly undignified circumstances.

Late last week, our colleagues at TechConnect highlighted an Amazon deal for $50 off the Ring Video Doorbell Pro. That deal quickly disappeared, but good news: It's resurfaced at Best Buy. The big box retailer is selling the Ring Video Doorbell Pro for $199 this week instead of the usual $249. The Ring Video Doorbell Pro does just what its name suggests. It's a smart home doorbell with a camera that allows you to see who's at the door.

Tucked away in western Wisconsin, not terribly far from Minneapolis, sits a factory full of babies. This factory produces each baby in just 15 minutes, and sells them for $649 apiece. Many of them are given to teenagers, in a bid to keep them from having babies of their own. These'bot babies teach would-be parents and medical types how to care for a newborn, and let teenagers experience being awakened in the wee hours by a wailing infant so perhaps they'll think twice about pregnancy. Realityworks calls them RealCare babies and started producing them in 1994, when the dolls went by the name Baby Think It Over.

Robots are slowly making their way into the workforce, but there is one job humans may not mind these machines taking over – mowing the lawn. Honda has unveiled an autonomous robotic lawnmower that uses electric motors, sensors and three different programmable cutting patterns to take care of one of life's most tedious chores. Called Miimo, the robot is equipped with a minicomputer and is capable of recharging itself – when it hits less than 30 percent battery life, it heads back to its charging dock, reloads and returns to where it left off to finish the task. Honda has unveiled an autonomous robotic lawnmower that uses electric motors, sensors and three different programmable cutting patterns to take care of one life's most tedious chores - mowing the lawn Honda plans to release two models in the US starting in June – the Miimo 310 and the Miimo 520, which can cover up to 300 square miles. Both are equipped with three cutting modes that allow consumers to customize the look of their lawn.

In the near future, ocean search-and-repair specialists won't need arms or legs, according to one vision. In fact, they are destined to be much more slithery. "We try to get people to move away from the word snake because it's seen as kind of scary but even I find myself all the time calling it a snake," says Richard Mills from marine tech firm Kongsberg. If the idea of a swimming robot snake doesn't appeal, you might want to skip the next few paragraphs. I first mentioned Eelume to a friend who asked me whether I would be allowed to have a swim with it.

It has been more than six years in the making, but a German startup will finally have the chance to test its 18-rotor commercial drone in public airways. Designed by e-Volo, the Volocopter 2X has received approval as an ultralight aircraft and should receive'multicopter' type certification in 2018 – letting it be used as flying taxis in pilot projects. The 2X is a revamped version of the Volocopter VC200, which now boasts a sportier look, a lithium battery pack and can top speeds of 62 mph – making it more suitable for everyday use.

OITA – With forestry workers growing older, Oita Prefecture has embarked on a "smart forestry" initiative to reduce workloads, partly through the use of drones. Forests cover 72 percent of the prefecture, with most of them cultivated plantations. Despite the use of mechanization for cutting down trees, planting still involves hard physical work, including climbing mountain slopes while carrying nursery trees weighing up to 30 kg. Forestry association workers are currently the local industry's main workforce, but 44 percent of them are 60 or older. Young people are reluctant to join their ranks, due partly to the physical labor.
