Other notes
We are currently using a TurtleBot4 Lite equipped with an integrated RPLIDAR A1M8 sensor, and we would like to inquire about the possibilities for individual configuration of this sensor.
Specifically, we would like to understand:
Whether it is possible to modify sensor parameters on the RPLIDAR A1M8
How the LiDAR can be accessed programmatically (e.g., via SDK or driver interfaces)
Whether the sensor can be configured to only report measurements when obstacles are closer than a defined threshold, for example within one meter
In addition, we would appreciate clarification regarding measurement quality and confidence handling:
How are confidence or reliability values defined for measurements?
How is the final distance or position value calculated?
Does the LiDAR output an average value within a confidence interval, or is another method used?
Any documentation, references, or guidance on these topics would be greatly appreciated.
Thank you in advance for your support. We look forward to your feedback.
Best regards
