Robbe Derks' presentation on comma ai's "How it's made" is a fascinating glimpse into the intricacies of automotive technology. As a hardware engineer for comma 3X, his insights shed light on the cutting-edge innovations powering the autonomous driving revolution. It's clear that comma ai is driving the future of transportation, one algorithm and sensor at a time. Great talk! 🚗🤖 #AutonomousTech #InnovationUnleashed #FutureOfDriving

[tychepi]

Great talk, I must admit that I've become a fan of Robbe!

[noahtah]

it's actually quite complex - Robbe Derks

[karoldomanskirobotics]

Great work. Are there any reasons why you use Autodesk Eagle and not, say, Altium Designer for PCB design?
