This Tree-Pruning Robot Wields a Chainsaw

Robots wielding dangerous weapons never seems like a good idea, but that doesn’t stop engineers from continuing to create them. Case in point, this ”Pruning Robot With a Power-Saving Chainsaw Drive.”

chainsaw robotmagnify

It was developed by roboticists Yasuhiko Ishigure, Katsuyuki Hirai, and Haruhisa Kawasaki, and is capable of not only climbing up trees, but dismembering them without human intervention. The robot can spiral its way up tree trunks ranging from 2.3 to 9.8 inches in diameter, and easily lops of limbs up to about two inches in diameter.

It doesn’t matter how much smooth jazz you play as it tears up the tree, slicing off branches. It’s still a deadly machine. While the machine could definitely reduce the need for human labor, the fact that it can climb and slice limbs seems like a horror movie waiting to happen. Imagine what this thing could do if it latched onto your leg. Eesh.

This Absurd Laser Lighter Is 2000 Times More Powerful Than the Sun

I can’t stop watching this guy burn through different materials with a preposterously intense laser that he built into a Zippo case. Metal, plastic, wood, rubber—these are no match for the laser lighter. Uhh, this is dangerous.

Custom G36 Coilgun Energy Weapon: Bang to the Future

I always find Star Trek’s utopia future pretty dumb. The human race is never going to be perfect and live in harmony. Because… This thing. This gun from the future is all kinds of bad-ass. It looks like Smith and Wesson made love to TRON and left this bright glowing and deadly baby on our doorstep.

This is a fully-functioning coilgun that launches metal bolts with the power of electricity. The coilgun technology you see here was all jammed inside and around a G36 airsoft gun.

coilgun 2

It has a night vision infrared camera and viewfinder, lasers, and a magazine that holds batteries instead of bullets. And if you saw those three lasers at the end of the rifles barrels pointing your way, you’d better duck.

The future’s so bright… I gotta wear Kevlar.

Don’t Try This at Home: Norah the Jet Bicycle

Colin Furze has a need for speed, and he’s not afraid to get his hands dirty in order to speed up stuff that normally doesn’t go more than a few miles an hour. That’s because they’re not supposed to exceed those speeds, but hey, tell than to Colin.

If his name sounds familiar or if you feel like you’ve seen him before, then maybe you already have since he’s the guy behind the baby stroller that can go as fast as 50mph.

Jet Bike

This time around, Colin set his sights on a plain old bicycle.

When he was done with it, the bike had been completely transformed into a jet pulse bike. And because the previous owner of the bike was his friend’s mom named Norah, that’s what the bike has been named also.

The bike is elongated for two reasons: to fit the jet and to make sure that the cyclist doesn’t get burned while he’s on it. Colin explains: “Had I binned the pedals idea, yeah, it could have been shorter, but the heat this thing chucks of is intense, and at times I’ve struggled to turn a valve of 40 centimeters away from it, so sitting on top of it would need some sort of heat shield, and I think it would start to look less bicycle like.”

Because of this, Norah was cut and stretched by almost one meter. Check out the video above to see this insanely dangerous ride in action.

Robot with a Chainsaw: It’s the End of the World as We Know It.

What genius gave this robot a chainsaw? This industrial robot has been programmed to carve logs into stools. With a chainsaw. Is this really a good idea? Uh, probably not. The Texas Chainsaw Massacre will now become the Robot Chainsaw Massacre. I look forward to it’s endless sequels.

These stools from Germany’s Echtwald get sold to the people who came to watch the robot in action. So you watch this robot cut your stool and then you buy the stool, thanking god that this thing can not follow you home.

It’s almost like blackmail. Here, watch this robot carve up a stool. That could be you getting carved up if we let this thing loose. How about you buy one of these stools now? Yeah, I thought you might need a place to park your butt.

Homebrew Stun Baton: Dangerous DIY

Are you a problem-solving field agent who refuses to use a gun to defend yourself? Or are you an Equalist looking to cover your subpar chi blocking skills? Then you’re as real as my readers. Badum-tish! You’ll also appreciate this stun baton made from off-the-shelf electronics and some recycled bits and pieces.

stun baton by pode coet

The baton is a pet project of UltraKeet member PodeCoet. It works by stepping up the voltage of a 4v battery to 10,000 volts through several stages, starting from two booster converter circuits, then to an inverter and finally to a voltage multiplier. Watch the result in the video below:

Head to UltraKeet for the full instructions. If you haven’t guessed by now this involves next level hackjutsu and is extremely dangerous. Also PodeCoet’s walkthrough is funny but it’s also made with colorful language, so best leave the young ones off of this one. Here’s an excerpt:

You need only get close to, and not phsyically touch these components to get a jolt, which may lead to Ventricular Fibrillation.

You can die (or sh*t your pants, sometimes both) while building this device. We are not liable for any losses or injuries, and cannot answer any support queries regarding this build.

Edit: Yes, you can still die, even if you know how to program an Arduino.

Not Even the Dark Knight Would Use This Insanely Dangerous Knife [Weapons]

Batman is best known for his wonderful arsenal of gadgets and weapons, but even with a suit of bulletproof body armor the caped crusader probably still wouldn’t touch this scary-looking knife with a ten-foot batpole. More »
