the idea of a living structure fascinates heiko hammond he's not a gardener but a robotics expert and he heads a project called flora robotic and. his team in lubec studies and develops symbiotic relationship between robots and plants here red and blue lights are set up to steer plants. the robotic sensing and control elements helped produce living architectural structures. we're building an autonomous system distributed robotic system that can independently change the direction plants grow and. no one had tried this before so we had to do a lot of the basics. to find out what kinds of sensors really work and how bright the area delight's need to be. the assailant is sign we have to do a lot of technical engineering work to get it up and running. and so. sensors measure distance to a plant and thus its growth if it's supposed to change direction the light source moves. blue light attracts the plant. by dosing the color the robotic elements control the direction in which a climbing plant grows. the right these braided structures are the basis for more complex architectural forms. the b
