Abstract
In recent years, legged robots have emerged as powerful mobile robots capable of navigating complex and uncontrolled environments where wheeled robots often fail. This review provides a comprehensive overview of recent studies and advances in legged robot locomotion and control, focusing on integrating fundamental control strategies. The paper begins by examining the evolution of legged robot designs, from early prototypes to quadrupeds and humanoids. It then discusses critical locomotion modeling, including simplified spring-mass systems and full-body dynamic simulations, and highlights how they utilize control strategies. Recent developments in model-based control, such as whole-body and model predictive control, are compared with emerging learning-based methods like reinforcement learning and hybrid control architectures. This paper additionally focuses on addressing the challenges of sensing, terrain adaptation, and the integration of perception for real-time gait adjustment. Finally, the paper identifies ongoing challenges such as energy efficiency, robustness, and sim-to-real transfer, offering perspectives on future research directions. This review aims to serve as a valuable resource for researchers and practitioners seeking to advance the capabilities of legged robotic systems.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
