Watch this robotic samurai beat a master swordsman in a slicing match

Add as a preferred source on Google

An army of robotic samurais? Believe it or not, such a ridiculous-sounding thing might soon become possible. In a video recently released by Japanese industrial equipment company Yasakawa, one of hte company’s MOTOMAN-MH24 robotic arms can be seen mimicking the movements of the record-holding master of the Iaijyutsu sword style, Isao Machii.

To demonstrate the robot’s abilities, the company placed motion sensors on Machii’s body and 3D scanned his movements as he sliced through objects with his katana. That information was then analyzed and programmed into the robtic arm, allowing it to replicate Machii’s movements exactly. The precision with which the robotic arm slices objects with the katana can be seen in the video below:

The robot takes on Machii in a number of complicated challenges, such as angled cuts and slicing a runner bean lengthways, and manages to execute them with perfect speed and precision every time. 

The robot outdoes Machii in the final “thousand cuts” section — an endurance match which involves slicing a thousand straw mats. While Machii is visibly sweating and tired, the robot on the other hand seems ready for a thousand more. For reference, Machii is the same guy who holds the record for slicing an 80 mph flying shrimp and a 150 mph rubber ball mid-air before they swiftly ended him.

As per the information available on the company’s website the MH24 robot was originally designed for industrial purposes such as assembly, dispensing, material handling, and packaging applications — but that’s clearly not all it can do. 

Although the robotic arm is seen precisely replicating Isao’s movement, it must have required good amount of tweaking and re-do’s, to give it the abitlity to automatically adjust mid-swing.

Let’s just hope this sucker doesn’t find itself a set of legs and an artificial brain. We could be in some serious trouble if that happened!

Flipper Busy Bar

Flipper Devices has built a reputation among hackers and hardware enthusiasts with the Flipper Zero, a pocket-sized gadget capable of interacting with RFID, NFC, Bluetooth, and other wireless protocols. Now, the London-based company is taking a very different approach.

Its latest product, the Busy Bar, is a desktop productivity display designed to help users stay focused, signal their availability, and automate parts of their workflow. After being teased last year, the device is finally going on sale on July 14. While the concept is genuinely clever, its starting price of up to $249 may make many buyers think twice.

Supersonic Flight Time

The dream of flying faster than the speed of sound just took a major step forward. The Federal Aviation Administration (FAA) has announced a proposed rule that would create the first noise-based certification standards for a new generation of supersonic passenger aircraft, removing one of the biggest regulatory hurdles standing in the way of commercial Mach 1+ flights.

The goal is simple: fly faster without the boom

NotebookLM’s 60-second videos turned my doomscrolling curse into something useful
Electronics, Mobile Phone, Phone

Short videos have taken over just about every app we use. You scroll through them on X, lose track of time on Instagram, watch them on YouTube, and now even Netflix has its own bite-sized feed. So when I heard that Google was bringing the format to NotebookLM, it felt both surprising and completely inevitable at the same time.

Google has announced Short Video Overviews for NotebookLM, a feature that turns dense documents and complicated sources into 60-second vertical videos that explain key ideas. Instead of staring at pages of notes, you get a quick visual walkthrough of the concept you're trying to understand.
