Successfully interfaced Arduino Mega 2560 with Hokuyo URG-04LX-UG01 LiDAR using a USB Host Shield 2.0 from Circuits @ Home....the LiDAR gives the device descriptors fine....next step is to send the VV commands and receive info from LiDAR using other USB library functions.....
I'll mount this lidar on ardupilot mega quad once this is done....planning to send lidar data to GCS via XBee....
So the modules connect like this:
LiDAR -> USB Host Shield -> Arduino Mega 2560 (on quad) -> Xbee -> GCS -> ROS
Comments
In our project, we're first using LiDAR as a map-building unit, and an aid for navigation. We'll be using the on-board GPS and IMU in first pass; if things go good, we'll try for navigation in GPS-denied environment...
Coincidentally, I actually happened to get my hands on one of these as well although I have the classic URG-04LX that is apparently a whopping $2300. The advantage of this version is that it has a serial interface but I guess to save $500, using the usb host shield is a darn good idea.
I'm very interested to see how you're going to mount it on the arducopter. I was thinking of making a 3d printed mount.
One challenge is that it's 270 degress, not 360 so for object avoidance you would still need a rear facing sonar (or you need to turn around every now and then to be sure you're not backing into anything!)
Sounds like an Open Source project dying to get started.
It depends on the quality of the system, but there are complex RF parts on the design. Everything has to be designed to the best linearity. The processing power inside the module has to be quite great. But mostly the price is in engineering. You will spend years in research, paying PHDs to develop a really complex system that will not sell millions. It is going to cost a lot.
unfortunately the cheapest 2D Lidars still cost above $1000 bucks......i saw the neato hack project though...do u guys have any idea of which part of LiDAR makes it cost more....?? the laser module, rotation servos, triangulation arrangement, cmos camera, processor.....none of these added together i guess would make it more than $100....
I'll be using it for building 2D maps (on GCS) to aid path planning....so yes, end usage is aircraft navigation....
Are you using it for aircraft navigation or survey (if the latter what RTK will you use?)
Mike
what about this?
Cool! (If only it didn't cost $1,200...)
