Powered by Artificial Intelligence (AI), Machine Learning, Computer Vision, and advanced sensors, humanoid robots are becoming smarter every year. They are already helping in hospitals, factories, schools, hotels, and even space exploration.

What is a Humanoid Robot?

A humanoid robot is a robot designed with a human-like appearance and body structure. Most humanoid robots have:

• A head
• Two arms
• Two legs
• Hands with fingers
• Cameras (eyes)
• Microphones (ears)
• Speakers (voice)

Some humanoid robots can also display facial expressions, hold conversations, recognize emotions, and make decisions using AI.
