Autonomous Robot Anti-Stasis and Anti-Tilt Escape Mechanism

The robot performs preliminary actions by executing escape maneuvers at the first sign of constraint detection, preventing complete immobilization. The anti-stasis behavior is triggered proactively when constraints are detected, rather than waiting for total failure, allowing the robot to maintain mobility while minimizing the duration of escape operations.

The inertial measurement unit serves multiple functions: it detects robot tilt relative to gravity, monitors robot orientation during movement, and provides data for both anti-stasis and anti-tilt behaviors. This multi-functionality reduces the need for separate dedicated sensors, thereby limiting the increase in device complexity while maintaining reliable constraint detection.

The robot employs feedback control by continuously monitoring tilt sensor signals and executing anti-tilt behaviors only when tilt thresholds are exceeded. This feedback mechanism ensures cleaning stability is maintained during normal operation while minimizing corrective maneuvers to only when necessary, thereby reducing the time lost to stabilization actions.

The robot dynamically adjusts the wiggle angle based on the number of escape attempts. The wiggle angle increases with each subsequent failed escape attempt, allowing the robot to adapt its escape strategy to overcome increasingly stubborn constraints. This dynamic adjustment improves escape success rate while distributing mechanical stress across multiple attempts rather than applying maximum force immediately.
