I am a strong believer in open-sourcing whatever I can so that others may learn from my work, as I have learned from countless others.

Gradient optimization for inverse kinematics
Inverse kinematics is one of the hardest problems in robotics. Given desired goal position and orientation for an end-effector, inverse kinematics seeks to find a suitable series of joint configurations to meet that goal. In this paper, we develop a forward kinematics model in Python and apply gradient-based methods using automatic differentiation to develop an inverse kinematics model of an arbitrary $n$-joint robot arm. We evaluate the performance of standard gradient descent against Nesterov Momentum gradient descent. We conclude with a discussion of the limitations of our 2D model and areas for extension to gain more fidelity with real-world robots.

Design factors for database query domain-specific languages (DSLs) in object-oriented languages
Most applications that interface with a database are written with object-oriented programming (OOP) languages. Many applications use SQL databases to persist data. There exists an ‘impedance mismatch’ between the use of object-oriented systems that act on objects of non-scalar values and the storage of scalar values (e.g. strings and integers) organized in SQL tables.

Remembrance Agent for Java
Java-based implementations of a remembrance agent, a continuously running automated information retrieval system, based on work by Bradley Rhodes of MIT Media Lab (1997). Available as a standalone, no-dependency Java/Gradle project and as a desktop graphical user interface (GUI) featuring integrations with Google Cloud Speech APIs, Gmail, Google Drive, and locally-stored plain text (.txt) or Markdown (.md) files. Open-source and freely-available under the MIT License. Under active development.
