The current humanoids on sale are a sophisticated combination of mechanical engineering and software and they're taking on diverse roles.

2. NAO is a humanoid robot with rich interactive capabilities.
Nao is actually a teaching aid. You can bring STEM to life
with NAO, and teach core subjects like Reading, Writing,
Mathematics, and even programming.
By using the NAO Evolution – V5 platform, instructors and
researchers stay current with major technical and
commercial breakthroughs in programming and applied
research.

4. Nexi is a mobile humanoid robot, MIT Lab’s star robot,
developed in 2008. The head does seem oversized, but
that’s because it can display a wide range of facial
expressions. And, it’s fitted with video cameras and
microphones, which enable it to see and hear.

6. With its all-white face and its stubs, everything about
Telenoid does look creepy. But Telenoid is a portable
tele-operated android robot that’s been designed to
represent human presence. It gives people the feeling
that the person they’re speaking with at a distance, say,
over the phone, is right next to them because the
caller’s movements are physically communicated to the
receiver by Telenoid.

8. Zeno R25, an interactive humanoid robot that’s been
described as the world’s first affordable advanced social
robot. Just 22 inches high, it looks like a toy, but it
actually has some fairly sophisticated technology in its
humanoid form. The Zeno R25 reads books, tells
interactive stories, and can answer questions by
searching online for answers. It can conduct lessons for
primary school students: history, science, geography
and mathematics. It can teach languages and give you
practice. And it can dance to music and initiate
conversation based on what people are doing.
