Full Sculpture

Objectives

During the fourth and last week of the COSMOS Cluster 2 on Engineering Design and Control of Kinetic Sculptures, our team has to integrate the Mini Sculpture concept(s) into a working Full Kinetic Sculpture. Lesson learned during the prototyping of the Mini Sculpture are now applied to ensure the Full Sculpture operates autonomously and is robust to any design or programming errors found during the Mini Sculpture design.

Design Requirements

The requirements for the Full Sculpture are as follows:

Must run automatically on its own and without having any marbles falling from the sculpture.
At least one sensor and one servomotor. The motor must act upon input from the sensor.
Include a Chain Link ball return machine as well as the original Mini Sculpture.
One human interface to interrupt/override the automatic operation.
No use of duct tape, cardboard, glue, etc.
Use Working Model 2D to provide a realistic simulation of part of our full Kinetic Sculpture.
User output which displays relevant information to the person interacting with the sculpture.

Brainstorming

When coming up with our final design, we knew we wanted to increase the size of the sculpture, since our Mini Sculpture hadn't been too large in size. However, since we had a limited amount of time to finish our final sculpture, we thought it would be more beneficial to focus on making our whole sculpture consistent, rather than going for crazy ideas that may or may not work. We decided to add an extra area to our sculpture, which increased the size as we had hoped for, but was also not too risky.

Our Design

In our design, we met the requirements as follows:

Our sensor and motor are the same ones that were originally in our Mini Sculpture, a color sensor that then told the motor to move, which separated red and yellow balls onto two different tracks.
In the new section, we added an additional motor that operated based on time, as well as another Chain Link ball return machine (in addition to our already existing one)
Our human interface was the same as the one in the Mini Sculpture, with the two buttons that allowed a user to move the sensor up and down.
Our Mini Sculpture was still a part of the Big Sculpture, but we just added another section onto it.
