Drones Rearrange This Canopy Prototype So You're Always in the Shade

When they're not rebuilding the environment or exploring Mars, the drones of the future may help us avoid some of life's minor inconveniences. A group of masters students at the University of Stuttgart envisioned a fleet of drones that does just that for their thesis project: As New Atlas reports, the drones are part of a roaming canopy, responding to sunlight above and movement below to ensure you're always in the shade.

Without the drones, the prototype, dubbed Cyber Physical Macro Material, resembles a normal stationary structure. Tall black poles support panels that fit together magnetically, protecting whoever's beneath them from the sun's rays. But this design is only effective when the sun is in a certain part of the sky: As the day progresses, the canopy's shadow shifts, and people are forced to move with it if they want to stay out of the light.

But these panels don't stay in the same spot for long. They come equipped with special sensors that keep track of the orientation of the sun and a communications system that corresponds with autonomous drones nearby. If a panel is no longer keeping the ground beneath it shady, a drone will glide over, lift it up, and snap it into a different part of the canopy like a puzzle piece. Drones can also rearrange the panels in response to the size and location of the crowd beneath them, which means the same structure that shades a few pedestrians can also keep a larger party cool.

There are legal and logistical hurdles the project would need to overcome before becoming a system in a real-world, but the researchers behind it say that for now it's meant to get people thinking about the potential applications for drones. A press release from the university reads, "With its ability to continuously reconstruct during use, the system challenges pre-conceived ideas of robotic digital fabrication and sophisticated pre-fabrication for architecture."

Charge Your Gadgets Anywhere With This Pocket-Sized Folding Solar Panel

Portable power banks are great for charging your phone when you’re out and about all day, but even they need to be charged via an electrical outlet. There's only so much a power bank can do when you’re out hiking the Appalachian Trail or roughing it in the woods during a camping trip.

Enter the SolarCru—a lightweight, foldable solar panel now available on Kickstarter. It charges your phone and other electronic devices just by soaking up the sunshine. Strap it to your backpack or drape it over your tent to let the solar panel’s external battery charge during the day. Then, right before you go to bed, you can plug your electronic device into the panel's USB port to let it charge overnight.

It's capable of charging a tablet, GPS, speaker, headphones, camera, or other small wattage devices. “A built-in intelligent chip identifies each device plugged in and automatically adjusts the energy output to provide the right amount of power,” according to the SolarCru Kickstarter page.

A single panel is good “for small charging tasks,” according to the product page, but you can connect up to three panels together to nearly triple the electrical output. It takes roughly three hours and 45 minutes to charge a phone using a single panel, for instance, or about one hour if you’re using three panels at once. The amount of daylight time it takes to harvest enough energy for charging will depend on weather conditions, but it will still work on cloudy days, albeit more slowly.

The foldable panel weighs less than a pound and rolls up into a compact case that it can easily be tucked away in your backpack or jacket pocket. It’s also made from a scratch- and water-resistant material, so if you get rained out while camping, it won't destroy your only source of power.

You can pre-order a single SolarCru panel on Kickstarter for $34 (less than some power banks), or a pack of five for $145. Orders are scheduled to be delivered in March.

Watch Ford's Sweaty-Butt Robot Put a Car Seat to the Test

Buyers tend to look at price, safety, and gas mileage when shopping for a car; a question that rarely comes up at the dealership is how well a car seat stands up to years of butt sweat. But even if it isn't a priority for car owners, the vehicle testers at Ford work to ensure the cars that leave the factory can accommodate the sweatiest passengers.

The secret to Ford's durable seats is a device called the Robutt. This video from the car company shows a Kuka robotic arm pushing a buttocks-shaped cushion into a car seat. To replicate a person sitting in the car after exercising, the dummy butt is heated to approximately human body temperate and pumped with half a liter of water. The average person produces about 0.7 to 1.5 liters of sweat in one hour of intense exercise, and people who are especially fit perspire 1.5 to 1.8 liters in the same time.

The sit test is repeated 7500 times over three days—simulating one decade of someone driving their sweaty behind home from the gym. If the surface of a car seat can make it through all that abuse without any wear and tear, the design is good enough for a Ford vehicle. Robutt-approved seats were first introduced in the 2018 Ford Fiesta and are now being built into all Ford vehicles in Europe.

You can watch the messy process play out below. Here are some more robots that, like the Robutt, were designed for oddly specific tasks.
