Apple's Tim Cook: 'News was kind of going a little crazy' – CNET

The CEO also says Apple has to speak out about things like immigration and human rights because if it didn’t, it would be “in the ‘appalling silence of the good people’ category.”

DARPA design shifts round wheels to triangular tracks in a moving vehicle

As part of its Ground X-Vehicle Technologies program, DARPA is showcasing some new defense vehicle tech that’s as futuristic as it is practical. One of the innovations, a reconfigurable wheel-track, comes out of Carnegie Mellon University’s National Robotics Engineering Center in partnership with DARPA. The wheel-track is just one of a handful of designs meant to improve survivability of combat vehicles beyond just up-armoring them.

As you can see in the video, the reconfigurable wheel-track demonstrates a seamless transition between a round wheel shape and a triangular track in about two seconds and the shift between its two modes can be executed while the vehicle is in motion without cutting speed. Round wheels are optimal for hard terrain while track-style treads allow an armored vehicle to move freely on softer ground.

According to Ground X-Vehicle Program Manager Major Amber Walker, the tech offers “instant improvements to tactical mobility and maneuverability on diverse terrains” — an advantage you can see on display in the GIF below.

While wheel technology doesn’t sound that exciting, the result is visually impressive and smooth enough to prompt a double-take.

The other designs featured in the video are noteworthy as well, with one offering a windowless navigation technology called Virtual Perspectives Augmenting Natural Experiences (V-PANE) that integrates video from an array of mounted LIDAR and video cameras to recreate a realtime model of a windowless vehicle’s surroundings. Another windowless cockpit design creates “virtual windows” for a driver, with 3D goggles for depth enhancement, head-tracking and wraparound window display screens displaying data outside the all-terrain vehicle in realtime.

TechCrunch is hosting an event in Hangzhou July 2-3

Pack those bags, TechCrunch is taking a road trip. We’re hosting an event at Hangzhou’s Yunqi Town International Convention and Exhibition Center, July 2 and 3, featuring some of China’s top names in technology.

The event kicks off Monday July 2, with a conversation featuring Alibaba Cloud co-founder Wang Jian. We’ve also got interviews with a range of tech executives from Microsoft China, Rokid and Ecovac robotics, covering a wide range of topics, from VC funding in China to AI and robotics. You’ll find the full schedule for both days over here.

The event will also feature multiple side stages with numerous panels focused on such key categories as autonomous vehicles, VC and blockchain.

As is customary for TechCrunch events, we’ll also have plenty of companies on the show floor at our Startup Alley space. This year’s tech will primarily be focused on these key categories: blockchain, the smart home, transportation and robotics, along with international launches and interactive/media booths. The event will also be host to a meetup expressly targeting VCs and entrepreneurs.

TechCrunch editors will be on-hand at the event, and we hope to see you there. Tickets for the event can be purchased here.

This smart prosthetic ankle adjusts to rough terrain

Prosthetic limbs are getting better and more personalized, but useful as they are, they’re still a far cry from the real thing. This new prosthetic ankle is a little closer than others, though: it moves on its own, adapting to its user’s gait and the surface on which it lands.

Your ankle does a lot of work when you walk: lifting your toe out of the way so you don’t scuff it on the ground, controlling the tilt of your foot to minimize the shock when it lands or as you adjust your weight, all while conforming to bumps and other irregularities it encounters. Few prostheses attempt to replicate these motions, meaning all that work is done in a more basic way, like the bending of a spring or compression of padding.

But this prototype ankle from Michael Goldfarb, a mechanical engineering professor at Vanderbilt, goes much further than passive shock absorption. Inside the joint are a motor and actuator, controlled by a chip that senses and classifies motion and determines how each step should look.

“This device first and foremost adapts to what’s around it,” Goldfarb said in a video documenting the prosthesis.

“You can walk up slopes, down slopes, up stairs and down stairs, and the device figures out what you’re doing and functions the way it should,” he added in a news release from the university.

When it senses that the foot has lifted up for a step, it can lift the toe up to keep it clear, also exposing the heel so that when the limb comes down, it can roll into the next step. And by reading the pressure both from above (indicating how the person is using that foot) and below (indicating the slope and irregularities of the surface) it can make that step feel much more like a natural one.

One veteran of many prostheses, Mike Sasser, tested the device and had good things to say: “I’ve tried hydraulic ankles that had no sort of microprocessors, and they’ve been clunky, heavy and unforgiving for an active person. This isn’t that.”

Right now the device is still very lab-bound, and it runs on wired power — not exactly convenient if someone wants to go for a walk. But if the joint works as designed, as it certainly seems to, then powering it is a secondary issue. The plan is to commercialize the prosthesis in the next couple of years once all that is figured out. You can learn a bit more about Goldfarb’s research at the Center for Intelligent Mechatronics.
