As part of group work in one of my engineering classes I worked on an Arduino powered autonomous robot. The robot has motor driver circuits and feedback loops manually implemented on a breadboard, with an ultrasonic sensor for obstacle detection. The autonomous robot was able to collect temperature, light, and humidity data, writing all collected data onto a local SD Card.
In one of my robotics classes I implemented the "R*" pathfinding algorithm that allowed a digital robot to find its way through an obstacle filled room with the shortest path. The robot had a LIDAR scanner that would take in data from the room, and I was able to create a configuration space map of the room that the path tracing algorithm was able to find a path through.
As part of a web development class I worked in a 5 person team developing a music recommendation website using node.js and the Spotify web API. This website allowed the user to input certain words related to spotify genres and songs, and get a list of recommendations back. The user could then create a playlist of the recommended songs that would be directly added to their spotify account.
