This is the project repo based on the final project of the Udacity Self-Driving Car Nanodegree: Programming a Real Self-Driving Car. For more information about the project, see the project introduction here.
This is a simplified version without using ROS. The whole system including the server and the simulator can be run in Windows, Mac OS, and Linux environment.
The tserver.py uses threading to perform several tasks required in path planning, motion control and traffic light detection. The yserver.py is a simplied version without using threading.
Sending the brake command will release the throttle even if (brake==0).
