Sobot Rimulator is robot simulator and programming tool, built for practicing mobile robot control theory. It is an open-source project built in Python.

Georgia Institute of Technology provided a link to Sobot Rimulator as an option to students of the January 2014 iteration of their Coursera course "Control of Mobile Robots."

Recursor is a tree fractal creator.

This is a small project that I did with React, Redux, and TypeScript to help me practice the latest best practices in these technologies. I found the entire experience very enjoyable and fun.

Rooftop solar system engineering is a complex task which requires the combination of panels, inverters, and other components with the right properties and in the right configuration to produce the most power for your buck. Traditional solar engineers may take several days or weeks to come up with the correct inventory of components.

SolarBear was a free online tool which allowed users to generate these optimal configurations within seconds simply by providing their budget, power requirements, and other factors.

The script follow_wall_controller.py delineates the operational conduct of a mobile robot navigating close to an obstacle's surface. By leveraging positional data from wheel odometry and proximity sensor readings, the algorithm calculates the relative location of the obstacle's surface to the robot. Subsequently, it generates control parameters that facilitate the robot's movement along the obstacle's surface, maintaining a predetermined "standoff" distance.

This script represents one of the numerous potential behaviors the robot can adopt. For instance, without obstacles in the robot's trajectory, an alternative controller would guide it directly toward its ultimate destination. A state machine that continuously scrutinizes sensor readings manages the transition between different behaviors, exemplifying the "hybrid automata" approach to mobile robot control design.
