Altitude-Sensing Arduino Robot

Westlake High School

Spring 2022 Engineering Course Final Project

For the final project in the Intro to Engineering course in my senior year of high school, I assisted with the design and creation of an Arduino robot that would fall from the top of the stadium bleachers, be slowed by a parachute, and take a picture from a specified altitude. 

The project required many things, such as keeping our structure under a 25-pound weight limit, as well as designing our own Arduino circuit and C++ code that would accomplish the task. Due to this being a group effort, I was tasked with the design of the housing for the circuit and the parachute. I had to plan how to construct this chamber to hold the circuit with a balanced center of gravity so it would remain upright, hold the camera so that it would be pressed by the servo motor, and make and attach a parachute so that it would deploy without tangling all while keeping the weight under 25 pounds.

To keep the weight limit and the Arduino circuit sound, I constructed a cage with minimal popsicle sticks and hot glue that would hold each major part of the circuit firmly in place and balanced with the others. I then went through many iterations of trashbag parachutes finally creating one that was cut and glued to a proper shape and attached using long twine and a dowel-rod frame that would keep it from tangling itself. 

When it was time to launch the final robot, we were under the weight limit and the robot glided perfectly down as designed.
