Nightmare-Inducing Headless Cheetah Robot Learns To Jump

In case just being a headless cheetah robot wasn't scary enough, a group of researchers at the Massachusetts Institute of Technology (MIT) have now given their robot the ability to autonomously detect oncoming objects and jump over them.

This is no easy feat. The robot doesn't just hop, it relies on a visual system that maps terrain using reflections from a laser to spot an obstacle and calculate when and where it needs to take off, and then automatically adjusts its stride accordingly.

"A running jump is a truly dynamic behavior," Sangbae Kim, an assistant professor of mechanical engineering, told MIT News. "You have to manage balance and energy, and be able to handle impact after landing. Our robot is specifically designed for those highly dynamic behaviors."

But perhaps most impressive is that unlike how you might assume a robot works, the headless cheetah doesn't necessarily look for the optimal takeoff location, just one that will work.

"If you want to optimize for, say, energy efficiency, you would want the robot to barely clear the obstacle—but that’s dangerous, and finding a truly optimal solution would take a lot of computing time," Kim said. "In running, we don’t want to spend a lot of time to find a better solution. We just want one that’s feasible."

On a treadmill—with very little time to prepare itself—the robot cleared about 70 percent of the hurdles up to 18 inches (over half its height) tall. Out on a track, with room to really stretch its horrifying, sci-fi legs, it improved to clear about 90 percent.

The Most Popular Infomercial Product in Each State

You don't have to pay $19.95 plus shipping and handling to discover the most popular infomercial product in each state: AT&T retailer All Home Connections is giving that information away for free via a handy map.

The map was compiled by cross-referencing the top-grossing infomercial products of all time with Google Trends search interest from the past calendar year. So, which crazy products do people order most from their TVs?

Folks in Arizona know that it's too hot there to wear layers; that's why they invest in the Cami Secret—a clip-on, mock top that gives them the look of a camisole without all the added fabric. No-nonsense New Yorkers are protecting themselves from identity theft with the RFID-blocking Aluma wallet. Delaware's priorities are all sorted out, because tons of its residents are still riding the Snuggie wave. Meanwhile, Vermont has figured out that Pajama Jeans are the way to go—because who needs real pants?

Unsurprisingly, the most popular product in many states has to do with fitness and weight loss, because when you're watching TV late enough to start seeing infomercials, you're probably also thinking to yourself: "I need to get my life together. I should get in shape." Seven states—Colorado, Idaho, Kentucky, Montana, Nebraska, Utah, and Wisconsin—have invested in the P90X home fitness system, while West Virginia and Arkansas prefer the gentler workout provided by the Shake Weight. The ThighMaster is still a thing in Illinois and Washington, while Total Gym and Bowflex were favored by South Dakota and Wyoming, respectively. 

Kitchen items are clearly another category ripe for impulse-buying: Alabama and North Dakota are all over the George Forman Grill; Alaska and Rhode Island are mixing things up with the Magic Bullet; and Floridians must be using their Slice-o-matics to chop up limes for their poolside margaritas.

Cleaning products like OxiClean (D.C. and Hawaii), Sani Sticks (North Carolina), and the infamous ShamWow (which claims the loyalty of Mainers) are also popular, but it's Proactiv that turned out to be the big winner. The beloved skin care system claimed the top spot in eight states—California, Mississippi, Nevada, New Mexico, Oklahoma, Oregon, Tennessee, and Texas—making it the most popular item on the map.

A Florida Brewery Created Edible Six-Pack Rings to Protect Marine Animals

For tiny scraps of plastic, six-pack rings can pose a huge threat to marine life. Small enough and ubiquitous enough that they’re easy to discard and forget about, the little plastic webs all too often make their way to the ocean, where animals can ingest or become trapped in them. In order to combat that problem, Florida-based Saltwater Brewery has created what they say is the world’s first fully biodegradable, compostable, edible six-pack rings.

The edible rings are made of barley and wheat and are, if not necessarily tasty, at least safe for animals and humans to ingest. Saltwater Brewery started packaging their beers with the edible six-pack rings in 2016. They charge slightly more for their brews to offset the cost of the rings' production. They hope that customers will be willing to pay a bit more for the environmentally friendly beers and are encouraging other companies to adopt the edible six-pack rings in order to lower manufacturing prices and save more animals.

As Saltwater Brewery president Chris Gove says in the video above: “We want to influence the big guys and kind of inspire them to also get on board.”
