The objective of this project was to build a robot health assistant that tracks electrodermal activity (EDA), body temperature, and heart pulse to give feedback on mental health.

45% of Americans feel mid to high level stress. Stress and anxiety lead to potential negative health effects, and it's increasingly important to track these for self-awareness. In order to achieve this, my partner and I divided the project into two parts: 1) health detector and 2) robot feedback. The health detector will analyze EDA, body temperature and heart pulse to send a positive or negative result. The robot will provide feedback based on these results by nodding or shaking its head. 

​

My main focus was to design the health detector. In my circuit, I incorporated wiring to read EDA signals, a temperature sensor, and a pulse sensor. These readings are assessed based on average thresholds and will output a negative result if one reading is within an unreasonable range. After I coded this logic in Arduino and built the circuit, our work was combined, giving life to our robot health detector! Circuit design and logic flowchart for the health detector are shown in the images below.

​

From this project, it was clear that sensor data can fluctuate a lot due to environment or instability. I learned that health and lie detectors require a more robust system and higher expertise, but this solution is a cheap alternative.
