Scientists Use Hops to Power Up Insect-Sized Flying Robots

What they are saying certainly makes a lot of sense, when you think about the mechanics behind a grasshopper being able to fly, versus a … fly.

Insect-scale robots face two major locomotive challenges: constrained energetics and large obstacles that far exceed their size. Terrestrial locomotion is efficient yet mostly limited to flat surfaces. In contrast, flight is versatile for overcoming obstacles but requires high power to stay aloft. Here, we present a hopping design that combines a subgram flapping-wing robot with a telescopic leg. Our robot can hop continuously while controlling jump height and frequency in the range of 1.5 to 20 centimeters and 2 to 8.4 hertz. The robot can follow positional set points, overcome tall obstacles, and traverse challenging surfaces. It can also hop on a dynamically rotating plane, recover from strong collisions, and perform somersaults. Compared to flight, this design reduces power consumption by 64 percent and increases payload by 10 times.

I wrote about this briefly back in 2018, in reference to 1970s research, given the challenges with insect-sized flying robots.

The Insectothopter was plagued by inability to fly in actual weather, as even the slightest breeze would render it useless.

Scientists Prove Crows Can Do Geometry

A new German study proves crows can see the world in terms of geometry.

The perception of geometric regularity in shapes, a form of elementary Euclidean geometry, is a fundamental mathematical intuition in humans. We demonstrate this geometric understanding in an animal, the carrion crow. Crows were trained to detect a visually distinct intruder shape among six concurrent arbitrary shapes. The crows were able to immediately apply this intruder concept to quadrilaterals, identifying the one that exhibited differing geometric properties compared to the others in the set. The crows exhibited a geometric regularity effect, showing better performance with shapes featuring right angles, parallel lines, or symmetry over more irregular shapes. This performance advantage did not require learning.

Tesla Lawsuit May Allege “Collision Warning” Data Was Faked to Increase Insurance Profit

It’s easy to see how Tesla came up with this opaque and unaccountable plan. First they tell people Tesla insurance will be more efficient and less expensive. Second they create a complicated mess and charge people far more.

A potential class-action lawsuit filed in California claims that Tesla Insurance overcharged customers by incorporating erroneous forward-collision warning data, which allegedly triggered automatic safety score downgrades and led to higher premium costs.

The potential lawsuit, regarding claims of fake data used to scam customers, already has made a difference according to insurance industry news.

Tesla Insurance Services Inc. has eliminated forward-collision warnings as a metric in its Safety Score Beta program, which evaluates driver behavior to determine collision risk and influences insurance premiums. The update, reflected in the transition from version 2.1 to 2.2 of the Safety Score Beta, no longer includes these warnings in the calculation of a driver’s risk profile.

Think about the “safety” logic of a “collision warning”. It basically could have been programmed so Tesla would print money, raising rates on basis of a opaque “warning” without any burden of proof.

Polestar Awarded “Close to Perfect” Child Safety Score

The latest leader board on car safety tests, specific to features protecting children, rates Polestar engineering significantly ahead of the competition.

The programme director at Euro NCAP, Dr. Aled Williams, said the Polestar’s performance was “tantalisingly close to a perfect score and shows how a commitment to the safety of all occupants can pay off in providing outstanding protection in the event of an accident. 

“Car makers continue to rise to the challenge of making our vehicles and roads safer, and Polestar deserves recognition for setting a new standard, no matter how small the improvement may seem.”

Polestar’s latest SUV wasn’t the only model under the microscope; the Cupra Terramar, BYD Sealion 7, Jaecoo 7 and Geely EX5 SUVs also netted five-star scores, as did the new Audi A6. Yet it’s important to note that despite these strong ratings, Euro NCAP did find some faults with many of these models.

The article even calls out Polestar engineers for preventing the car from locking when a child is inside. Think about a common sense feature getting called out as special, or unusual.

The attention to detail is perhaps notable, even if expected, because of so many horror stories about rescuers smashing windows to save kids trapped inside the infamous South African madman Tesla that German courts have ruled a death trap.

When Kassandra stepped out to disconnect the charger, her Tesla unexpectedly locked her out, with her 13-month-old baby boy, Liam Valenzuela, still inside. “I started banging as hard as I could, but it wouldn’t break,” the mom said. Tesla’s security cameras captured the dramatic ordeal.
