repurpose automotive radar for UAV/UGV

Hello, I was interested in trying an automotive radar for collision avoidance on a UGV. Automotive radar should be cheaper than LIDAR due to scale production and no moving parts, and requires less…Continue

"Hey Zach, I work with Kvaser, so it's nice to see the Leaf Light in the tool chain above : )  Just as an FYI: - You're probably using CANking to record the log file, right?  You can also replay a log file or send specific…"

"I haven't worked on this in a long time. As pointed out by James M earlier, the firmware on the radar used in the ohio university thesis is surely not the same as the firmware in the audi part."

"Hi, XCP on CAN is interesting. The measurement bandwidth is quite limited compared to proper XCP on ethernet, but it should be sufficient to measure some simple info depending on how heavily loaded the CAN bus is already.  There are a few…"

"You're right. It seems to be very hard to get those automotive radars working out of the car. What I've read so far (and what it makes it even more difficult) is the fact, that audi (where the sensors used here come from) have component…"

"You're correct that there is some limited self correction functionality, but the sensor has no way of knowing where it is and where it's pointed. It needs to be told these things via diagnostic commands which are either executed at the end…"

"Hi. the alignment procedure you describe is correct, but the fine calibration (+/- 0.8°) the sensor does itself. And because only the LRR itself knows it's actual position, my thought was that there must be any kind of a sensor which…"

"Hi, There is no gyro or accelerometer on the LRR3 or any automotive radar that I know about, they typically receive data on the vehicle motion from the ESC system.  The alightment error is because the system needs to be aligned to very high…"

"Hi there, I've bought one lrr3 but hadn't any time to test it yet. As far as I know, the Bosch sensors have some kind of gyroscope onboard and throw out an error on CAN when the sensor isn't aligned properly. I've seen that you…"

"Hello Kuba, * I'm not sure what type of sensor should I use, but due to poor range of sonic or laser sensors (I need at least 40m/130ft) I think that I have no other choice than radar sensor. LIDAR is possible but expensive. There was some…"

"No progress. A log of the canbus messages from a working vehicle is required. Currently only fancy cars have LRR. If/when they become more common then someone will do it."

"Hell guys, I found the following report/thesis about LRR2 system: https://upcommons.upc.edu/pfc/bitstream/2099.1/6629/1/PFC_MarcMirTutusaus.pdf Looks like it uses a TI chip that combines a MCU with a DSP. Any updates from the OP?"
