Elowan is a “plant-robot hybrid” that uses its own bio-electromechanical signaling to drive itself around toward light sources. From an explanation by researcher Harpreet Sareen and his colleagues at the MIT Media Lab:
In this experimental setup, electrodes are inserted into the regions of interest (stems and ground, leaf and ground). The weak signals are then amplified and sent to the robot to trigger movements to respective directions.
Such symbiotic interplay with the artificial could be extended further with exogenous extensions that provide nutrition, growth frameworks, and new defense mechanisms.
