As far as consumer drones went, Skydio had the absolute best technologies. How so? Using the smartphone/tablet live video feed from the airborne drone, an operator could select an object to track, and the Skydio drone will autonomously follow it. For example, say you wanted to go on a forest run and wanted your drone to film you. Not only was it doing real-time SLAM and path-planning, but the drone attempted to keep the subject best in frame. The tech stack was seriously impressive. Here's a robotics secret: the "best" autonomous systems use factor graphs. With factor graphs, you can represent complex systems of equations while avoiding sparse matrices. That combo allows sufficient efficiency to do SLAM on resource-constrained robots. Look up GTSAM for more information. There's a direct connection between GTSAM and Skydio.

HBM3e memory bus width is 1024 bits versus GDDR's 32. That only works because the memory is tightly integrated into the processor core, whereas (G)DDR is from an era where memory was placed far away from the processor.

Own the sensors, own the data. If you hold title, you own the vehicle and all its subcomponents, including the sensors. Manufacturers will fight otherwise because they profit off the vehicle data, but it's your property producing the data.
