Watch MIT’s ‘mini cheetah’ robots frolic, fall, flip – and play soccer together

MIT’s Biomimetics Robotics department took a whole herd of its new ‘mini cheetah’ robots out for a group demonstration on campus recently – and the result is an adorable, impressive display of the current state of robotic technology in action.

The school’s students are seen coordinating the actions of 9 of the dog-sized robots running through a range of activities, including coordinated movements, doing flips, springing in slow motion from under piles of fall leaves, and even playing soccer.

The mini cheetah weights just 20 lbs, and its design was revealed for the first time earlier this year by a team of robot developers working at MIT’s Department of Mechanical Engineering. The mini cheetah is a shrunk-down version of the Cheetah 3, a much larger and more expensive to produce robot that is far less light on its feet, and not quite so customizable.

The mini cheetah was designed for Lego-like assembly using off-the-shelf part, as well as durability and relative low cost. It can walk both right-side up, and upside down, and its most impressive ability just might be the way it can manage a full backflip from a stand-still. It can also run at a speed of up to 5 miles per hour.

Researchers working on the robot set out to build a team of them after demonstrating that first version back in May, and are now working with other teams at MIT to loan them out for additional research.

Roku puts a remote on your wrist with new Apple Watch app

The Roku remote is coming to your wrist. The company announced today the launch of an Apple Watch app that lets you control your Roku device, including Roku media players and select Roku TVs, with a tap — just like the Roku mobile app, but sized for your wrist.

Considered the limited screen real estate, the app is fairly robust in terms of its feature set.

In addition to the expected media controls — like the ability to play and pause what you’re watching –, the app also offers a home button, the select button (“OK”), a back button and directional arrows. And it includes a way to launch your favorite channels, which are organized in order of the most recently launched to make them easier to access. That way, if you always watch Netflix, you don’t have to scroll down to find it.

In addition, the tiny remote app includes voice search functionality. To activate, you just tap the voice icon, then say things like “Launch Hulu” or “search for comedies,” or even change sources, like “switch to HDMI 1” for your Roku TV, the company explains. This will work on Apple Watch versions 1 through 5.

And if you have a Roku Ultra or a Roku TV with the Remote Finder functionality which uses an audible chime to locate a lost remote control in the couch cushions, you can also use the Roku Apple Watch app to signal your Roku remote to start making a noise.

All these features will be familiar to anyone who has already used the Roku remote for smartphones, as the Apple Watch app is just a miniaturized version. The only thing it’s missing is the ability to stream The Roku Channels’ free movies, but obviously that’s not a feature you’ll want on your wristwatch. (I mean…right?)

To get the Roku Apple Watch app, you’ll need to download or update your Roku iOS app to the latest version (6.1.3), and the app will appear on your Watch as long as you haven’t disabled “Automatic App Install” in the Watch’s Settings.

China’s news and data site 36Kr tumbles in its stock market debut

36Kr, a Chinese news and data website that tracks startups, fell 10% in its Nasdaq debut on Friday.

The disappointing debut followed 36Kr’s decision to slash the size of its offering from 3.6 million shares to 1.4 million and pricing its shares at $14.5, the bottom of marketed range. This meant that the firm, which had initially aimed to raise as much as $100 million, settled for $20 million. A company top executive said that even as the offering is smaller, it has great confidence in its stock’s future performance.

The nine-year-old Chinese company’s decision to list in the U.S., instead of doing so in Hong Kong especially during the ongoing trade war between the two nations also surprised many.

In an interview with Yahoo Finance on Friday, 36Kr founder and co-chairman Cheng-Cheng Liu said the company decided to go public on Nasdaq because “our team thinks the U.S. stock market is one of the most matured markets in the world. Also, we have business outside of China.”

36Kr provides financials on companies, market updates, and commentaries. It maintains an English website as well and makes money through ads and multiple subscription offerings. The company could look to expand its business in North America in the future, said Liu. He also said that the company is betting that “the U.S. and China will be friends again.”

Liu said the recent instances such disappointing debut of Uber and tremendous fall of We, which postponed its public debut, should not affect 36Kr’s performance because unlike other companies 36Kr is “not cash burning” and has been profitable. In the first half of 2019, 36Kr generated a revenue of $29.4 million, a 179% year-over-year increase

The company, often called “Crunchbase* of China,” counts Ant Financial, Matrix Partners China, e.ventures, and Infinity Ventures among its investors and has raised over $100 million in venture fund. Crunchbase, which late last month raised $30 million, started as part of TechCrunch and has since spun out.
