OHMC2019 Software instructions

Overview

From a software perspective, the DonkeyCar (Raspberry Pi) is self-contained ... driving, data acquisition (for training) and ultimately self-driving are all performed with on-board software. The provided micro-SD card already has all the required software pre-installed, as well as two pre-training A.I / Machine Learning models. The DonkeyCar software includes a web-server that provides a web interface that works on both desktop and mobile web browsers (great for driving).

Your laptop will be required to perform training of the Neural Network ... using the data acquired on the DonkeyCar. This means that Python software will need to be installed, e.g TensorFlow (Machine Learning framework).
