Humanoid Robot

That's a fantastic achievement! Building a humanoid robot from waste material is no small feat, and it's impressive that a 9th school student was able to accomplish this in the year 2014-15. The length was about 4.5 feet and built this robot using completely useless material It's great to see young people taking an interest in robotics and using their creativity and problem-solving skills to build something new.

If you are that student, I would encourage you to continue exploring your interest in robotics and engineering. There are many opportunities to learn more about these fields, both in school and outside of it. You might consider taking courses in computer science, electronics, or mechanical engineering, or participating in robotics competitions or clubs.

Building a humanoid robot from waste material is just the beginning - there are many other exciting projects and challenges waiting for you in the world of robotics. Keep learning, experimenting, and building, and who knows what you might be able to achieve in the future!
