What are some challenges in developing humanoid robots with human-like capabilities, and how do researchers address issues such as balance, agility, and natural interaction with humans in designing anthropomorphic robots?

Challenges include designing humanoid robots with bipedal locomotion, multi-modal perception, and social cognition skills comparable to humans. Researchers employ techniques such as dynamic stabilization, biomimetic sensors, and expressive interfaces to enhance robot agility, perception, and communication abilities, enabling natural and intuitive interaction with humans in various contexts, such as healthcare, entertainment, and assistive technology.
