I am trying to filter out the data that hit my robot by using laser_filters to discard the data that its range is smaller than the radius of my robot. However, no matter how I change the parameter of LaserScanRangeFilter, even to an extreme value, the data is unchanged, the data in /scan_filtered topic is totally the same with /scan topic. I am running the laser_filters in groovy.

By the way, the ScanShadowsFilter and InterpolationFilter worked totally fine. The following is my configuration:

scan_filter_chain: -name: range type: LaserScanRangeFilter params: lower_threshold: 100 upper_threshold: .inf

Can anyone tell me how to solve this?
