tars

Tars may refer to different things in various contexts. In anatomy, the tarsus (tarsals) is the cluster of seven bones that form the ankle and the proximal part of the foot. These bones are the talus, calcaneus, navicular, cuboid, and the three cuneiforms (medial, intermediate, and lateral). The tarsus connects with the tibia and fibula to form the ankle joint and provides a balance of stability and range of motion for foot movement.

In popular culture, TARS is the name of a fictional humanoid robot in the 2014 science fiction film Interstellar. The character is notable for its modular, reconfigurable design and its dry sense of humor, and it serves as a companion to the astronauts on their mission.

Beyond these uses, the term Tars does not have a single, widely recognized definition applicable across all disciplines. Most references to Tars are either anatomical discussions of the tarsus or references to the Interstellar character, with other uses being rare or context-specific.
