Cool project! Thanks for sharing Two questions to know a bit more: - how long did it take you to complete that project? - what is the rough total cost?

My first car took about a week. The second one took a day. The total BOM was around 400$. Note: I am not great with hardware.

What took you so long the first time or: did you reuse compiled code the second time?

The first time I was building Donkey for an entirely new (and previously unsupported) SBC - the Asus Tinkerboard S. I was also unfamiliar with how everything was put together.

The second time was a breeze. Jetson Nano runs Ubuntu so getting everything to work was relatively easy.

Which books did you read and what was your experience with them?

George Hotz, former apple device jail-breaker left Tesla to start working on Self-Driving Cars, the DIY approach. So far he has been training the cars with HD Maps and has had decent progress considering his competition. http://comma.ai

That freaking awesome! I was thinking about making a self driving RC car with image recognition to hunt down some rabbits in my yard, maybe you can help me with that!

Great job man, great job!

That's a lot of mis-information. Hotz exchanged some tweets with Musk but never worked for Tsla. Comma uses cameras, not HD maps.

Tiny self driving vehicles could be fun and safe way to transport small things. Think an army of cleaning drones gatherings trash to a collection point.
