World's smallest humanoid robot

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

Four students, Aaron Ho Yat Fung, Isaac Zachary To, Justin Wang Tou Yang, and Ngo Hei Leung, from Diocesan Boys' School in Hong Kong, have created the smallest humanoid robot ever recorded, IFL Science reported on February 16. At just 14.1 cm tall, this robot is 11.3 mm shorter than the previous world record holder, Zain Ahmad Qureshi from Pakistan, who built it in 2022.

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

After designing the robot using software provided by the school's robotics lab, the student team fabricated the body parts using acrylic and 3D-printed components. Then, custom-made servo motors were installed, enabling the robot to move its arms and legs. The micro-humanoid robot is powered by an integrated 7.4-volt lithium-ion battery and can be remotely controlled via an app or buttons on a control panel on the robot's back.

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

By designing the smallest possible robot, mass production costs can be reduced, making the robot cheaper and more accessible to underprivileged families. "The team plans to publicly release the design and programming code to further advance STEAM education," Isaac said.
