Four students from Deusisan Boys School in Hong Kong achieved an impressive engineering feat by creating the world's smallest human-like robot, surpassing the previous record set in 2022, according to Business Insiders.

The height of the new robot is 141 mm, which makes it shorter than the length of a regular pen. The achievement of the four students received a Guinness World Record certificate for breaking the record, and the robot appeared in one of the episodes of the periodic “Records Weekly” series on the YouTube platform.

The robot also met stringent standards by building prominent human-like features, including having shoulders, elbows and knees, and being able to walk on two legs.

The journey of manufacturing the robot began by drawing engineering plans using computer-aided design programs. Once the technical specifications were completed, the students collaborated with a factory to manufacture servo motors to special standards. This type of motor is necessary to move the robot's limbs accurately and smoothly.

In addition, the team obtained a 16-channel robotic servo control panel to enhance the ability to control the robotic manikin.

With all the necessary components in hand, the students set about building the robot, starting by building the legs using eight motors to enable movement in the feet, knees and hips. They then focused on building the arms, incorporating fine motors in the shoulders and elbows. To account for the size, the students made modifications to the control panel, and used a precisely sized lithium battery. The control panel was installed on the back of the robot, with the ability to send commands via a pre-programmed mobile application, according to Guinness.

  • Aside from achieving the world record, the four students sought to design their work to be small in size, at a reasonable price, programmable and shipping, and intended for publication in educational workshops. The initiative also targets low-income families and disadvantaged students, so that the benefit can be achieved on the largest scale.
