Objective:
You are to make a heliotropic field that is responsive to the movement of the sun. Use this project to build on previous work and to refine your understanding of a heliotropic system. Is it possible that the shadow of one cell might affect its neighbor? Is it possible for cells to work together to share the available sunlight?
For presentation:
-Digital Project model and animation
-Operational prototype of 3 working / related cells.
Our group worked really well together this week. We met briefly after receiving our assignment on friday and then broke up for some independent brainstorming. On sunday we met for a brief team brainstorm where we were able to agree upon a design an delegate work to get this thing started.
My main job was to build the physical model and work out the movement. After making a rough sketch model Josiah Damien and I met to get the arduino hooked up and test the movement. We worked things out and I was off to clean up and expand our model.
Replacing what were originally t-pins with round headed sewing pins we made awesome Macgyver-esque ball joints!
These ball joints created a great pivot point so that we were able to achieve our goal of a stationary base and separate plane moving in shear.
In this test run our movement is quite smooth. Some team members were skeptical about using rubber bands to keep the plane in tension, but by using the bands we were able to achieve the desired movement with only two (rather than four) servos. Each servo is paired with a rubber band so that when the servo returns to its starting position the plane remains in motion.
The clip below shows our final model.
