Four members of the Robotics team from the Diocesan School for Boys in Hong Kong have set a new world record by creating the world’s largest humanoid robot. This achievement surpasses the previous record set by Zaina Ahmad Kureshi from Pakistan in 2022.
The robot created by the team stands at a height of only 141 mm, which is 11.3 mm shorter than a standard ballpoint pen. The Guinness Book of Records has officially recognized this achievement and showcased the robot in a video on YouTube. You can watch the video here.
The students have equipped the robot with an impressive range of articulation, allowing it to move its shoulders, elbows, knees, and hips. They have also achieved biped movement. The process started with computer design to develop drawings, followed by the selection of necessary components and the creation of specialized servomotors.
Servomotors play a crucial role in the robot’s functionality by enabling precise limb movement. To synchronize the complex components, the team utilized a 16-channel servo control board. Additionally, they acquired essential details such as screws, nuts, wires, and batteries.
The assembly of the robot began from its feet, using 8 servo drives to ensure leg, knee, and hip movement. The hands were then assembled with servos for the shoulders and elbows. During the assembly process, the team replaced the battery with a more compact lithium-ion battery (7.4V) and placed the control board on the robot’s back, allowing for control via a mobile application. All the robot components were 3D printed.
Aside from setting a world record, the robot was designed to serve as a multifunctional educational tool. The aim is to provide access to STEAM education (Science, Technology, Engineering, The Arts, Mathematics) for ethnic minorities and low-income families. This project promotes inclusivity and accessibility in the field of technological education.
