✨ Interesting thing from the past.
In the 1950s, MIT researchers introduced the light pen, a device that allowed users to interact with CRT monitors almost like today’s touchscreens. The pen worked by detecting the bright spot created by the electron beam on the screen. As the spot passed under the pen’s tip, a built-in sensor would determine its position.
This tech was similar to the light guns used in early video games. It found use in early graphics terminals and even music workstations in the 1960s and 1980s. However, it had its downsides, like causing "gorilla arm" from holding your arm in front of the screen for too long.
👉 Despite its limitations, the light pen was a key step in the evolution of interactive technology, paving the way for modern touch interfaces.

😈 Robotic tentacles.
Engineers in China have built robotic tentacles for drones and androids. These flexible arms can grab objects of any shape, twist 360°, and lift 260 times their own weight.
Powered by a clever system of cables and motors, these tentacles can be attached to almost anything.
👉 Terrifying? Maybe...

🏔 Cliff-climbing excavators.
Imagine an excavator that can work on super steep hills where no other machines can go. Komatsu’s special excavators are made for this.
With hydraulic legs that can tilt the tracks up to 70°, these machines stick to the terrain like mountain goats. And just to be extra safe, they’re often secured with cables to make sure they don’t slide off the mountain.
What’s even cooler? You can swap out the attachments for different jobs, and some models can even be controlled remotely. Perfect for working in the toughest, hardest-to-reach places.
