🧠 Advanced Computing & Open Innovation

For those pushing the boundaries of AI, the As2-W offers an expandable brain:

Processing Power: Supports an expansion module capable of 150 TOPS for real-time, on-device data crunching.
Applications: Ideal for high-stakes security, industrial inspection, and autonomous patrol.
Developer Ecosystem: An open SDK and comprehensive APIs allow for the integration of Large AI Models, enabling embodied AI and complex decision-making.

# Example conceptual SDK call for autonomous navigation
import unitree_sdk

robot = unitree_sdk.As2W()
robot.set_mode("SIDE_FOLLOW")
robot.navigate_to(target_coords={"x": 10.5, "y": 22.1})
print("Robot is now tracking user with ISS 3.0")
