Cool, fun project

Cool project! Last year I built self driving robot for my bachelor's thesis. Instead of building end-to-end deep learning pipeline I used two neural nets: one trained with…
evolutionas on HNNice work. I worked on a similar project where I created an adaptive cruise control prototype. I used a camera and a CNN to determine the distance from the car ahead of my car.…

Objections
Turns in place at boundaries, unrealistic turning radius
From 1 comment
Looking at the video, the toy car is turning in-place when it gets to the boundary. There is no realistic turning radius proportional to its size.

Uses Python 2, which is being deprecated
From 2 comments
Awesome project, but why Python 2? :( Pre-compiled Python wheels are available for Python 3 on Raspberry Pi at piwheels.org (default for pip in Raspbian)

Switch to Ackermann steering for realistic dynamics
From 1 comment
The toy car used differential steering with 2-wheels and a castor wheel. One of our ideas of future work was to change the current steering method for an Ackerman model, giving…

Questions
Does it use a single frame or previous frames?
From 1 comment
Does it "look" into a single frame or does it take previous steps into account as well?

Does training need a GPU?
From 2 comments
So all of the training was done without a GPU?
dmurthy on HNElaborating on my question. In your read me it says - "In the computer that you will perform the training -- protip: don't train the model in the Raspberry Pi! -- install all the…
