Plenty of cool things at CES but IMO the biggest breakthrough I saw was this $100 Lidar from Velodyne: https://velodynelidar.com/press-release/velodyne-lidar-introduces-velabit/
No moving parts! Sure seems to be a game changer. https://www.engadget.com/2020/01/07/velodyne-velabit-ces-2020/
It's aimed squarely at the automotive market. Brand new, just revealed at CES. One company https://www.roboticresearch.com/
had a drone flying with one, they've been doing hush-hush testing for Velodyne for some time now (they couldn't say how long). Their Pegasus line is drones specializing in inspecting bridges etc. Flies down from above, lands on treads that transform into blade guards in flight!
The Pegasus mini is the one that they showed with the new $100 Velobit Lidar. https://www.roboticresearch.com/defense/solutions/pegasus/
