Mobile robot algorithms: localization, planning & learning

Mobile robot algorithms: localization, planning & learning

Three interconnected projects from a mobile robotics course: UKF-based localization fusing odometry and landmark measurements, A* path planning with motion control, and a data-driven motion model learned with Locally Weighted Linear Regression.

Street sweeping tracker

Street sweeping tracker

Know before the grim sweeper comes. BroomBuster is a web app and Python CLI that shows where your cars are parked on a live map and tells you when street sweeping applies to that block. Supports multiple cities across the Bay Area and Chicago.
