Of course there's been progress, or we wouldn't be able to even start working on this project with such limited resources as we have now — that's like $5000 for total hardware (still 4u rack though, +INS, +cameras, no corrected GPS), the main problem being the inability to buy something like tBOX [0] with a more powerful CPU. Though we are counting on both our system getting optimized and industrial PCs catching up in a year or two.
What I meant to say, though things are a lot simpler now, they are not that simple to discount the Yet Another™ lidar-based self-driving car.
