Vital Monitoring Robot

What it is

This was an UtraHacks project. We built a small robot that follows a path, finds a patient location, takes a heart rate reading, and sends that data to a website. The idea was to help with basic monitoring in places where staff are stretched thin. It ties loosely to UN SDG 3 on health.

How it works

1. 1

   The robot follows lines on the floor to move between spots.

2. 2

   A colour sensor helps find patient locations, and a proximity sensor finds the hand.

3. 3

   An arm lowers a heart rate sensor onto the hand to take a reading.

4. 4

   Readings go to a website. The prototype runs on ESP32 boards with C++.
