Hong Kong students build the world's smallest humanoid robot

A group of Hong Kong students built a 14.1cm tall humanoid robot that can walk on two legs and move its arms, shoulders, hips, and knees .

A group of four students , Aaron Ho Yat Fung, Isaac Zachary To, Justin Wang Tou Duong and Ngo Hei Leung at Diocesan Boys' School, Hong Kong, built the smallest humanoid robot ever recorded , IFL Science reported on February 16. With a height of only 14.1 cm, this robot is 11.3 mm shorter than the old world record holder robot built by Zain Ahmad Qureshi from Pakistan in 2022.

The new record has been confirmed by Guinness World Records (GWR). To meet the record-setting requirements, the robot must be able to walk on two legs and rotate its shoulders, elbows, hips, and knees.

The new record has been confirmed by Guinness World Records (GWR).

After designing the robot with software provided by the school's robotics lab, the team of students fabricated acrylic bodies and 3D printed parts. Then, custom factory-made servo motors are installed, allowing the robot to move its arms and legs. The tiny humanoid robot is powered by a built-in 7.4-volt lithium-ion battery and can be controlled remotely using an app or buttons on the robot's back panel.

The group of students said that the small robot can walk, play soccer, dance, and even practice martial arts. In addition to being in the record books, the team's motivation for building the robot was to create a low-cost learning tool for use in STEAM (science, technology, engineering, arts and math) education. ).

By designing the robot to be as small as possible, the cost of mass production can be reduced, thereby making robots cheaper and more accessible to disadvantaged families. "The team plans to make the design and programming code public to continue toward the goal of promoting STEAM education ," Isaac said.
