Midterm Proposal: Piece of a 3D Mirror

Filed under: 7: Mid-Term Project,Assignments,Paul Castellana — paulcastellana @ 9:04 pm


My goal for this semester is to develop the foundations of a 3D mirror. Ultimately, I imagine this as a grid of hundreds of small blocks that would each move to “reflect” a point over a
complementary sensor grid. In this sense, each block would act as a pixel on a screen, except
instead of changing color they change height. So for the midterm I’m breaking it down to
just two blocks and two IR range sensors.

Code Sketch:

– Set servos to starting position
– Check inputs of range finders
– Convert input voltages into linear values
– If linear values fall within defined range, then move servos according to values
– If not, return servos to starting position


2 x Servo Motor
2 x GP2D120 IR Range Sensors
Building Material (haven’t decided on this yet)
