This bizarro bicycle reinvents the wheel … as a set of spider legs

When Californian art and engineering collective Carv began developing the Strandbeest-inspired walking bike in 2014, it couldn’t have known the beast that it would create. Carv had an idea. It had a simple blueprint of a Jansen’s linkage. It had a 3D-printed model of what the device might look like, some experienced craftsmen, and a few hours to spare for a few nights each week.

Seven months and 700 man-hours later, when Carv submitted its creation to the Santa Barbara Solstice Parade, it had half of a bike with three functional legs and over 450 custom-made components. “[We] couldn’t believe the thing actually worked,” the collective wrote yesterday in a Facebook post.

Carv’s customization efforts are impressive, but its bike wouldn’t exist if it weren’t for the work of Dutch artist Theo Jansen, who released his Strandbeests in 1990. The mechanical creatures are part works of art, part machines, and — according to Jansen — part lifeforms. Strandbeests (“beach beasts”) seem to be incredibly complicated, but function on a simple mechanism called a Jansen’s linkage that, when used in conjunction with other Jansen’s linkages, enable the creatures to walk.

Riding the Strandbeest Bike

Like land ships with legs, Strandbeests use sails to activate their joints and walk as the wind blows. Carv’s walking bike replaced Jansen’s sail with a couple pedals and a bike chain. As the cyclist pedals, the linkage the feet move back and forth, one before the other, like the legs of a shy spider.

Don’t expect to go very fast though. “One of the most common questions people ask is, ‘How fast does it go?’ or, ‘You should make it run off road,'” Jon Paul Berti, one of the bike’s creators, told Digital Trends. “It’s really not that kind of thing.  It requires a flat surface to work correctly, moves at a brisk walking speed, and it does not turn well.  We had some people try to ride it fast and it looks pretty nuts with the legs scuffling along that fast.  I’m sure it would break if they kept it up.”

Jon Paul isn’t yet sure if he’ll make the bike available for purchase any time soon. “We’ve had some requests,” he said, “but have not looked seriously into building them for sale. I can say that we put hundreds of hours into this project, and it would be very expensive to produce that way, but if enough people really wanted one, I guess we could look into finding a manufacturer.”

In the meantime, if you crave a bike like Carv’s, looks like you’ll have to head to shop and create one yourself.

Unitree Go2: Through the power of innovation you, too, can have a robot companion
Unitree Go2 robot companion with owner

How many of you can say you own an AI-powered robot companion to do your bidding? More specifically, an intelligent robot dog from the likes of Unitree. Probably not many of you, we'd wager, but there is an opportunity to change that. In the spirit of technical innovation and industrial leadership, Unitree has returned to its glorious bionic robotics roots -- please welcome the Unitree Go2. Available in three variants: Air, Pro, and Edu, the Go2 has been dubbed a "new creature of embodied AI." It's the next generation of the brand's innovative robotics, equipped with 4D LiDAR upgrades, an advanced AI mode, improved endurance and battery life, and a newly enhanced intelligent side-follow system with better positioning accuracy. What does it all mean, and what can it do? We'll get to that.

For now, know there's a 5% discount on the Go2 Pro with or without the controller when you use code UR5OFF at checkout. That saves you $140 on the Go2 Pro without a controller, bringing the price to $2,660. Or save $152 on the Go2 Pro with a controller, bringing the price down to $2,898. The controller allows you to operate and manually adjust the system without a phone. Meanwhile, you can use your phone and mobile app to interact with the Go2 Pro if you don't have a controller.

Toyota bets big on air taxis with $500M investment in Joby
Joby Aviation's electric aircraft flying in New York City in 2023.

Flying taxis, once the stuff of sci-fi movies, were widely expected to make a big splash by whizzing over the city of lights during festivities at the Paris Olympics last summer -- before getting scrapped due to certification concerns.

That isn’t stopping Toyota from pouring more money into air mobility.

The Tesla Supercharger network is expanding again

EV owners worried about getting stranded before their next charge may breathe a bit easier now: The Tesla Supercharger network has resumed its expansion over the last three months, after massive layoffs at Tesla had led to a slide in new stalls earlier this year.Tesla opened 2,800 new Supercharger stalls globally during the three-month period ending September 30, an increase of 23% from the year earlier, according to the company’s official Tesla Charging account on X (formerly Twitter).Tesla also delivered 1.4 terawatt hours (TWh) of energy during the third quarter, which translates to 27% year-over-year growth. The Tesla Charging account said the amount of energy delivered enabled Tesla owners to save over 150 million gallons of gasoline, offsetting more than 3 billion pounds of CO2.According to the website Supercharge.info, which relies on user contributions to track the opening of new stalls, there were 2,677 Supercharger stations in North America at the end of September, 125 more than at the end of the third quarter.The additions of new stalls, however, comes in the wake of a 31% slide in the second quarter, after a massive round of firings at the company removed 500 employees from the Supercharger team in April.The third-quarter expansion should still go some ways to appease the concerns of Tesla and non-Tesla electric vehicle (EV) owners, as EV manufacturers are lining up in droves to be able to use the Supercharger network.In September, General Motors electric vehicles made by Chevrolet, GMC and Cadillac joined the growing list of vehicles to have adopted Tesla’s North American Charging Standard (NACS). The network already allows access, via adapters, to EVs made by Ford, Rivian, Honda and Volvo. The likes of Nissan, Hyundai, Toyota, BMW, Volkswagen, Volvo and Jaguar have also signed agreements to start allowing access in 2025.
The Tesla map of Superchargers across the U.S. reveals they are concentrated in major cities and across East-West transit corridors.According to Tesla, a Supercharger can add up to 200 miles of range in 15 minutes.
