the plantoid moving towards stimuli and navigating unknown environment using tendrils, with hope of evolving the technology so that it can move against gravity. The GrowBot project displayed the ability of plantoids to position itself not only in terms of its roots, but the entire robot when stimuli is discovered. Plantoid Project The Plantoid project (2016) emphasized flexibility of roots through the use of springs and sensors that gave feedback when interacting with nutrient gradients or obstacles. This project took inspiration from plants and the roots' ability to overcame any obstacles that the environment presented. The feedback and response of the roots was replicated in this prototype, specifically how the root would move based on what objects the sensor picked up. The springs used in the roots allowed for more degrees of freedom compared to previous models of plantoids, and motors were combined with algorithms to effectively respond to feedback taken by the plantoid. The development of these sensors was accompanied by the development of algorithms that would place value on objects around the plantoid's roots (positive or negative) and lead to reactions based on if the object was deemed positive or not (roots move towards or away).
