A newly unveiled humanoid robot, standing just 80 centimeters tall, is challenging the traditional scale of robotic development by prioritizing portability and physical resilience.
Developed by Shanghai-based startup AgiBot, the AI-powered Q1 humanoid uses miniaturized Quasi-Direct Drive joints to deliver full-body force control in a frame roughly one-eighth the mass of standard adult-sized humanoids, small enough to be carried in a backpack.
At this scale, the implications extend beyond portability. In the field of robotics, the “sim-to-real” gap—the difference between a robot’s performance in a computer simulation and its behavior in the physical world—remains a major challenge. Traditionally, closing this gap with full-scale humanoids is a high-risk endeavor; a single hardware failure during a locomotion test can result in catastrophic damage and months of repair.

The Q1’s reduced mass and AgiBot’s Quasi-Direct Drive (QDD) joints are designed to make the robot inherently crash-resistant, allowing researchers to physically test complex AI walking and balancing algorithms with significantly lower stakes.
By shrinking the QDD joints to approximately the size of an egg while maintaining high dynamic response and full-body force control, engineers have created a system that can move with intent rather than the rigid, pre-programmed motion typical of smaller hobbyist robots. This high degree of control enables the machine to mimic the fluid dynamics of larger systems, making it a viable surrogate for laboratory experimentation.
Beyond its utility as a research tool, the Q1 is designed as an open-ended platform for embodied AI. The developers have open-sourced the HDK and SDK, offering custom exterior shells for 3D printing and zero-code motion programming. Users can customize the robot’s appearance, program movements, and experiment with embodied AI without advanced expertise in robotics.

While larger humanoids are increasingly aimed at industrial labor and tightly controlled environments, compact platforms like the Q1 point in a different direction. Their portability, resilience, and openness make them better suited to becoming personal robots rather than factory assets.
As systems like this move out of centralized labs and into classrooms, studios, and homes, humanoid robots begin to resemble customizable assistants or companions—machines that can be adapted to individual needs, spaces, and behaviors.
In that sense, the Q1 is less about replacing human work and more about making humanoid intelligence something people can live with, experiment with, and shape on a personal scale.
