zach w commented on Thomas J Coyle III's blog post Quanergy Announces $250 Solid-State LIDAR for Cars, Robots, and More
"It's exciting. Better than Velodyne.
It remains to be seen though what level of access the general public will get. For example, scanning radar is available in cars today and I'm sure costs much less than $1000 per sensor, but to get a device with…"

"Hi Gubenko,
No I didn't make progress and haven't worked on this for a long time. To reverse engineer the protocol a recording of the messages from a working vehicle is required."

Hello.I set myself a challenge of hooking up APMRover2 to a car simulated in MORSE and it seems to work so I thought I'd write about it. Might be interesting to someone.MORSE is a robot simulator based on Blender's Game Engine. MORSE is different to…

"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."

"An interesting development going around the tech news websites is this rear facing radar for bicycles
There's not a lot of detail but the "Open API" claim is encouraging."

zach w replied to e.Man's discussion WiFi Vehicle Group Project with Commercial Potential - who's interested?
I think OpenROV (http://openrov.com/) could be one source of inspiration. They've used an ethernet umbilical cord that could  be replaced with wifi. Using a small linux computer on the rover means you can benefit from the broad range of usb…"

"Hello Ryan,
I've used a RN-XV Wifly module with XBee Explorer regulated: https://www.sparkfun.com/products/10822 and https://www.sparkfun.com/products/9132
Together they have a problem, described in the comments on the sparkfun WiFly product page.…"

"Hello Mark, audi radars are available on ebay, just search for "adaptive cruise control".
I tried and failed, story here http://www.diydrones.com/forum/topics/repurpose-automotive-radar-fo...
I hope you can make progress."

"I'm interested to know how much the system costs, does anyone know?
There's an interesting paper that lists many indoor position technologies including Abatec here: e-collection.library.ethz.ch/eserv/eth:5659/eth-5659-01.pdf"

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 brains than stereo vision. I got a Bosch sensor…
