I think about the control for making new movement. Basically the plants use sun and water for energy. So, these elements affect to movements like a animal's food and water. It can control speed or moving pattern or place etc.
Sun and Water
So, I try to experiment technical test for this. I use humidity sensor and photoresist for sensing sun and water. The movements are expressed through servo actuator. I will try to make another movement with this next time.
