Design
Three Main Subsystems:I. Centerpiece (Linear Actuation)
The dynamic centerpiece was installed on the top of the
sculpture. Four-bar linkages were connected to a linear
actuator. The linkage was designed to create an interesting,
symmetric path. The linear actuator utilizes an internal power
screw.
II. Canopy (Rotational Actuation)
The tessellated canopy provides shade in an interesting
pattern for people sitting on the bench below. The canopy was
constructed out of ⅛” steel. The pattern was cut into the metal
using a laser cutter. A geared down DC motor turns the canopy
at a low speed.
III. Frame
The frame was constructed with 1½” square steel tubing. The
canopy had polycarbonate installed between the tubing to
provide protection for the moving parts. A bench was added to
the design at the bottom of the sculpture.
Power Systems
Two Main Subsystems:I. Solar Panels
Four 100 W high efficiency solar
panels were installed symmetrically
atop the canopy. The panels were
wired in parallel to a deep cycle solar
battery. In full sunlight, the panels
charge the battery in 3 hours.
II. Hand Crank Generator
People can interact with the sculpture
through the hand crank, which was
attached to a generator. The power
generated charges the battery and
powers several LEDs. More LEDs turn
on as the person turns the crank faster.

Overview
The objective of this project was to show the public that
sustainability and engineering share many core values.
We strove to accomplish this by highlighting different forms
of actuation, like linear and rotational, and powering them
through renewable resources such as solar and kinetic
energy.
The design we created was inspired by the simple elegance of
a tree, though mechanized and modernized to best convey the
blending of machine and nature.
Why a Sculpture?
A kinetic sculpture is arguably the most artistic medium that
still shares roots with mechanical engineering. By pursing an
artistic project we were given the freedom to design as
creatively as possible.
Most importantly, we believe that art allows us to connect with
people at a deeper level, which allowed us to promote
sustainable energy in a more meaningful way.
