January 2026 (2026-01) monthly summary for RobotLocomotion/drake focused on expanding modeling capabilities and improving simulation fidelity. Key features delivered include parsing support for linear spring-damper elements in SDFormat and URDF, enabling users to model multibody systems with spring-damper connections; and an accuracy boost for FEM external force integration by enabling additional quadrature points, improving results for deformable models. Both items were implemented via targeted commits, enabling broader application in design and analysis workflows.
