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.
