Figure 1-4 The RPLIDAR Sample Point Data Information
Figure 1-5 The RPLIDAR Sample Point Data Frames
The RPLIDAR outputs sampling data continuously and it contains the sample point
data frames in the above figure. Host systems can configure output format and
stop RPLIDAR by sending stop command. For detailed operations please contact
SLAMTEC.
High Speed Sampling Protocol and Compatibility
The RPLIDAR A2 adopts the newly extended high speed sampling protocol for
outputting the 8000 times per second laser range scan data. Users are required to
update the matched SDK or modify the original driver and use the new protocol
for the 8000 times per second mode of RPLIDAR A2. Please check the related
protocol documents for details.
Application Scenarios
The RPLIDAR can be used in the following application scenarios:
o General robot navigation and localization
