Robots Live in Uncertainty
A robot rarely sees the world perfectly. Sensors are noisy, objects move, floors are uneven and models are incomplete. Robust robotics is therefore less about commanding exact motion than continuously estimating, correcting and recovering.
Scenario: The Robot Misses the Same Pick Intermittently
Check perception confidence, calibration, object pose, gripper geometry, trajectory timing and contact forces. An intermittent miss may emerge from a small error distributed across multiple layers rather than one obvious component.
