He let a potted plant control a machete, fly a drone, and let a fly type on the keyboard to post. Netizen: It's so weird, take another look.

Please make a sentence using the three words "plant, robotic arm, machete".

You thought it was "a robotic arm holding a machete to chop plants"...

I never expected that someone came up with a device that "plants command the robotic arm to wield a machete".

#The camera zooms in, and you can see some sensors attached to the blades, and a circuit board connected to the wall.

Change to a few different perspectives, you can chop horizontally, vertically, and stab straight, and your moves are flexible and changeable.

Currently this video has tens of millions of views and 40,000 retweets. In short, it’s the “so weird, take another look” kind of video.

Some netizens joked that the next step is to study the Venus flytrap that controls the flamethrower in Super Mario.

Some people also suggested that it would be more interesting if you put a kettle and let it water itself.

Of course, more people are curious about how this is achieved and does the plant know what it is doing?

Author: Let plants fly drones

The author of the installation, David Bowen, is an experimental artist and, in his own words, a "kinetic sculptor."

Plant Machete is his latest work. The supporting text description explains:

This system uses open source micro The controller reads the signals on the blades and maps them to the joint motion of the robotic arm in real time.

Essentially, the plant is the brain that controls the robotic arm, determining how the machete swings and thrusts through space.

In the information provided by the author to the New Atlas website, more details were revealed.

He attached EEG sensors for electroencephalography to five leaves and connected them to the analog signal input of the Arduino development board. There was also a ground wire connected to the Arduino in the soil of the plant.

The signal received in this way is basically the variable resistance data of the blade, which is then mapped into a signal to control the movement of the robotic arm through a specific algorithm.

Netizens who saw this finally felt relieved. It turned out that the plant was not consciously wielding the machete, and it could not even sense the existence of the mechanical arm. It's like controlling a robotic arm with random numbers generated by nature.

However, some people have suggested that if you think about it this way, plants are not consciously performing photosynthesis...

This is not the first time David Bowen has tried to combine plants with machinery.

Not long ago, he used a similar method to make a plant-piloted drone.

Plants randomly determine the flight path, and with the LED bulbs and long-exposure time-lapse photography mounted on the drone, you can take some interesting photos.

In addition, he didn’t just toss the plants. In the early years, he also shut some flies together with the keyboard. Whenever the flies hit the If it reaches 140 characters or hits the Enter key, it will automatically send a tweet.
