R_4_06 — Skeleton Evolution and Biomechanics
Skeletal systems — structures providing support, protection, and movement — have evolved independently multiple times across the tree of life, representing one of the great themes in the history of life. Three fundamenta
R_2_08 — Bipedalism — Why We Walk Upright and What It Cost Us
Bipedalism — habitual upright walking on two legs — is the defining characteristic of the hominin lineage, predating brain enlargement, tool use, and language by millions of years. The earliest evidence comes from Sahela
S_1_07 — Virtual and Augmented Reality
Virtual reality (VR) creates fully immersive digital environments replacing the user's visual field; augmented reality (AR) overlays digital content onto the physical world; mixed reality (MR) blends virtual and physical
S_5_15 — Social Robotics: Companion Robots, Elderly Care, and Human-Robot Interaction
Social robotics — the design, construction, and study of robots intended to interact with humans in socially meaningful ways — occupies the intersection of robotics, artificial intelligence, psychology, and design. Unlik
