SICK LMS 291 LabView LIDAR Driver


Hello! As you probably know, I worked on sensors for DEXTER in the 2007 DARPA Urban Challenge. The first software I worked on was a LabView driver for the LMS 291 LIDAR laser scanner along with Amaury Rolin. We cleaned up and submitted our driver to National Instruments, and you can now download it from the NI Developer Zone. Hopefully this program will be useful to others! Good luck! :)

Hi Bradley, can this driver work at 500kbps? I failed to do so... error occurs at initialization vi... Should I make any change?

It will work at 500 kbps, assuming you are using RS-422 and your RS-422 interface supports that high speed. I was able to use the USB Gear / Coolgear 422 to USB adapters plasic enclosure and metal enclosure, which have a small buffer but are workable, as well as National Instruments' high speed PXI and PCI RS-422 interface boards like the 8431/4, which have a huge buffer and are awesome in general.

Hi Bradley, How can I use this driver with LMS 291 set to resolution 100/0.25? I cannot gather any data with the examples attached with the driver.

Cheng- If the device is reporting in this format, you will probably need to adjust the coefficients in Polar to Cartesian.vi
