Kentaro Iizuka developed expressive body yaw control for the pollen-robotics/reachy_mini repository, enabling more nuanced robot motion through the REST API. He integrated a new body_yaw parameter into motion endpoints and updated backend models to support this feature, using Python and type checking to ensure reliability. By aligning backend typing to accept None for body_yaw, Kentaro resolved type errors and improved API robustness. His work included comprehensive end-to-end validation in Mujoco and updates to JSON schemas, facilitating adoption by API consumers. This focused engineering effort addressed both feature development and bug resolution, demonstrating depth in backend and robotics API design.
November 2025: Delivered expressive body yaw control for pollen-robotics/reachy_mini and strengthened API reliability. Implemented body_yaw parameter across REST API and models, enabling more expressive motion commands; aligned backend typing to support None for body_yaw in set_target, preventing type errors and improving reliability; comprehensive end-to-end validation in Mujoco and updated JSON schemas.
