I think you’re right. Garbage collection companies, seen as a mobile sensor platform, probably can generate data (maps, wardriving, street view, AVL) worth more than their actual core business.

I think what’s more telling is the opposite implication. That despite ample sources of data, it’s not actually that valuable. Did you ever consider that the reason that self driving cars are overhyped is because the underlying science is bad, not that there is insufficient data? Wouldn’t it be in Waymo’s interest for everyone to believe that it’s all about data, while they bide time trying to make something that work…

The problem itself is difficult and the cost of making mistake is high. Thats why the progress is relatively slow.

Also, at least to my opinion, its not very clear that the market is big enough. Its highly unlikely that one single company can monopolize the market as there are quite a few rich companies with deep pocket and extremely talented team are investing in the same space.

If more than a dozen companies comes out with very similar performing self-driving solution. The markey may not be big enough to recoup the investment into this technology.

For the longest time I thought waymo was way ahead of everyone else - but the nature of their slow and passive progress in to the market doesn't give me a lot of confidence in their abilities.

They have a hardtime in relatively peaceful streets of developed world, how will technilogy work on the streets of developing countries where most people live?

I think the problem is extremely hard. And it will take a lot longer than most people initially though it would.

The most recent Eon isn't a OnePlus 3 it's a LeEco LePro 3. I don't see how it's really irresponsible also, it is a relatively complicated set up ( getting easier all the time ), but people definitely are aware this isn't a fully fledged product and that they should be keeping an eye at all times.

I was wondering what they were using since the Oneplus3 have been discontinued for so long. It's irresponsible because they wrote an apk that patches to a python script... They could at least have some portion written in some hardware language like C++, especially the safety check section. Also, when I first read it there was zero redundancy. They could at a minimum do a soft watchdog how ROS does it. Putting your Dr…

There is a microcontroller between the phone and the car that monitors all communication and enforces safety limits. This code is written in C++.

Sorry for being naive on this, but I have some questions: Looking at this, it appears that they have mounted this device on a car and just had it taking in all sorts of data to effectively feed dataset into a map that can be used by self driving cars, correct? If I were doing a project like this - I would attempt to work with waste disposal companies to put these sensors on every garbage company. Garbage companies wi…

Unfortunately the code powering OpenPilot is not very reliable. As the OP alluded to it's time-sensitive code written in (very hard to understand) Python.

It's not really that time sensitive. The main event loop for something like this only has to run at like 50hz. I didn't find the code to be all that hard to understand either (at least the car interface bits needed to port to another car).

How can this be not "really time sensitive"? The stability of these kind of controllers depend on smooth periods without jitter.

Putting these kind of controller on a phone written in Python is OK for a student project driving at 20 km/h on a closed off area. It actually madness and most likey illegal to use these modifications on public roads. Atleast it should be ...

I thought the microcontroller in the middle was doing the CAN injection only. Is this no longer the case?

Sorry, but where is a Jetson TX2 module available for <200$?

You can get a Jetson TX2 Kit (edu bundle for $299, I think normal is Around 599. https://www.nvidia.com/object/jetsontx2-edu-discount.html

Thanks for taking the time to share the link, was interested in diving into the deep rabbit hole for a self-driving contraption and 300$ off is quite an incentive.

Your welcome :)

It’s a nice board for sure (I have a few). I personally use a more powerful desktop setup with a few nvidia 1080ti cards, mounted in a trunk of a 2017 Honda. The tx2 is definitely a good platform for a powerful RC car setup or similar, especially with the discount. When it comes down to it, during the dev/learning cycle, any general setup will do.
