# LDS01RR_lidar

Some info and soft for LDS01RR Lidar (Roborock)  

LDS01RR_WinScan folder - ("LDS Scanning Test") - windows utility for drawing Lidar data.  

lds01rr_lidar folder - ROS node sources. Just run "make" command to build ROS node.  

  

See more info about this Lidar here: https://youyeetoo.com/blog/lds01rr-lidar-stdps01rmain-108  

Also some more info about previous Lidar from Roborock: https://github.com/Roborock-OpenSource/Cullinan  

  

You can see tests results in "Pictures/Testing folder"  

20 measurements are analyzed.  

Distance 3m, white wall - Std. Dev.: +-0.7cm, Max-Min=2cm  

Distance 5.84m, white wall - Std. Dev.: +-0.9cm, Max-Min=4cm  

Distance 9.46m, white wall - Std. Dev.: +-1.3cm, Max-Min=5cm  

  

Distance 6m, gray wall - Std. Dev.: +-1.6cm, Max-Min=5cm  

Distance 8.4m, gray wall - Std. Dev.: +-2.1cm, Max-Min=8cm, this was maximum stable distance  

  

Distance 4.4m, dark wall - Std. Dev.: +-1.2cm, Max-Min=4cm, this was maximum stable distance  

  

Distance 11.56m, white wall - Std. Dev.: +-2.0cm, Max-Min=7cm, LDS has inclination angle ~20 deg.  

It looks like that max distance for this Lidar is limited by 12m in its firmware.  

  

Notice that data protocols (between rotating head and integrated STM32F446 MCU) and VCP protocols are different.
