This is something you have to see to believe. Scientists gave a plant a machete and it letting it control it with an industrial robot arm. The real description below:
This installation enables a live plant to control a machete. plant machete has a control system that reads and utilizes the electrical noises found in a live philodendron. The system uses an open source micro-controller connected to the plant to read varying resistance signals across the plant’s leaves. Using custom software, these signals are mapped in real-time to the movements of the joints of the industrial robot holding a machete. In this way, the movements of the machete are determined based on input from the plant essentially the plant is the brain of the robot controlling the machete determining how it swings, jabs, slices and interacts in space.
