Ponsse’s Scorpion King is an eight-wheeled monster designed to “endure tropical heat and arctic cold, travel without destroying the terrain and briskly climb the steepest slopes.” That’s because it’s designed to get to and cut down trees down in tricky areas. And Ponsse has developed a “cut-to-length” method whereby the trees are stripped of their branches and cut into logs of precise length on the spot.
To achieve this, they designed a fairly terrifying saw-wielding robot koala bear suspended from the end of a massive boom arm. Watch as it outstretches its greedy little arms, eagerly embracing and mutilating one arboreal victim after another:
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

Reminiscent of the machine in GM’s Futurama exhibit that cut through the forest and put down a road in its wake.
