controller-frequency-tuning

Tune the Nav2 controller frequency by setting controller_frequency to 20 Hz and monitoring /controller_server diagnostics to balance CPU load and navigation responsiveness for indoor robot deployments.

Configuring MPPI controller parameters in ROS2 involves adjusting controller_frequency alongside velocity thresholds and failure_tolerance to reduce latency, jitter, and false positives during goal attainment.

Yes, controller frequency tuning applies across typical indoor robot tasks supporting MPPI, DWB, and FollowPath controllers to achieve the desired trade-off between responsiveness and CPU usage.

Fix Nav2 controller latency and false positive goal checks by tuning ancillary parameters like costmap_update_timeout, failure_tolerance, and velocity thresholds to ensure stable navigation.

Nav2 controller server timeouts occur when frequency and timeout parameters are misconfigured, requiring diagnostic guardrails like controller timeouts and goal progress checks to ensure safe operation.
