Artificial intelligence is unarguably the most exciting field in robotics. And Humanoid robots are one of the most popular forms of AI. They have even been portrayed in several Hollywood movies. However, there is no doubt that a robot can perform in an assembly line, but there is no consensus on whether it can ever be intelligent like humans. In some way, today's AI machines are able to replicate some specific elements of intellectual ability and are outpacing human experts in several areas, specifically in the diagnosis of critical diseases like cancer.

Initially, the prime objective of AI for humanoids was for research purposes. They were utilized for research on how to create better prosthetics for humans. But now, humanoids are being built for several purposes beyond research. They are developed to perform a wide range of human tasks and reside in different roles in the employment sector. Some of the roles they could occupy are a personal assistant, receptionist, front desk officer, among others.

The process of creating a humanoid robot is quite complex and requires a lot of work and research into the process. Most of the time, developers and engineers face crucial challenges, too. In this regard, first-grade sensors and actuators are imperative and a small mistake could result in glitches. With the assistance of certain features like sensors and actuators, humanoids move, talk, and carry out actions effectively.

Not all humanoids resemble humans as some are modeled after only some specific human parts such as the human head. Humanoid robots are typically either Androids – a humanoid robot designed to resemble a male human, or Gynoids – look like female humans. They work through certain features, as well as they have sensors assisting them in sensing their surrounding environments. They also have cameras that allow them to see clearly and motors that are placed at strategic points to guide them in moving and making gestures. These motors are usually referred to as actuators.

For humanoid robots to become as intelligent as human beings, they will have to be instilled with the ability to comprehend natural human language, known as natural language processing (NLP). As the development of humanoids still in its embryonic phase, a lot of work and researches require to make these robots mimic humans.
