The future goals for refining the robot's design include extending the capabilities of the upper body to perform a wider range of motions and gestures. This will enable the robot to tackle more intricate and fine-grained tasks, ultimately improving its ability to interact with humans and operate in various environments.

The expressive humanoid robot was developed by engineers at the University of California San Diego. The robot is trained to perform a variety of expressive movements, such as simple dance routines and gestures, while maintaining a steady gait on diverse terrains2. This development has implications for improving human-robot interactions in various settings, including factory assembly lines, hospitals, and homes.

The humanoid robot maintains balance on diverse terrains by training its upper and lower body separately. This approach allows the robot's upper body to replicate various reference motions while its legs focus on a steady stepping motion to maintain balance and traverse different terrains. The robot operates under a unified policy that governs its entire structure, ensuring it can perform complex upper body gestures while walking steadily on various surfaces.
