Baselink

Baselink is a term used in several technical domains to denote the foundational connection or anchor point within a system’s structure. It is not a universally defined term with a single formal specification, but it is commonly encountered as a compound of “base” and “link” indicating the lowest-level or starting element in a chain.

In robotics and related fields, baselink frequently appears as a variant of the root link that forms the base of a robot’s kinematic model. In common practice, the root link is named base_link in URDF and ROS conventions; baselink (or BaseLink) may be encountered in codebases or documentation that use different naming schemes or case conventions. The specific identifier can vary by project, but it generally designates the fixed frame from which other links are measured or connected.

Beyond robotics, baselink can appear as a general identifier in data models, graphs, or software that organize components into linked elements anchored to a base. Because it is not a formal standard, the exact meaning of baselink should be inferred from the surrounding documentation or codebase.
