Abstract
Purpose of ReviewAs new technological advancements are made, humanoid robots that utilise them are being designed and manufactured. For optimal design choices, a broad overview with insight on the advantages and disadvantages of available technologies is necessary. This article intends to provide an analysis on the established approaches and contrast them with emerging ones.Recent FindingsA clear shift in the recent design features of humanoid robots is developing, which is supported by literature. As humanoid robots are meant to leave laboratories and traverse the world, compliance and more efficient locomotion are necessary. The limitations of highly rigid actuation are being tackled by different research groups in unique ways. Some focus on modifying the kinematic structure, while others change the actuation scheme. With new manufacturing capabilities, previously impossible designs are becoming feasible.SummaryA comprehensive review on the technologies crucial for bipedal humanoid robots was performed. Different mechanical concepts have been discussed, along with the advancements in actuation, sensing, and manufacturing. The paper is supplemented with a list of the recently developed platforms along with a selection of their specifications.

For all intents and purposes, this review focuses on robots that aim to mimic the bipedal mobility of a human, and the recent advancements in technology that enable it
Summary
Humanoid robotics has come a long way in its development, with progress accelerating in its every branch by the years. What started as basic, yet fascinating automata has quickly grown into a global interdisciplinary research field in just half of a century. The intertwined dependence of theoretical concepts and available technologies is constantly shaping the evolution of humanoid robotics. Current humanoid robots are not the result of a single.
