Since the 1920s, scientist and engineers already started to develop self-driving car based on limited technologies. An adversarial attack in a scenario with higher consequences could include hacker-terrorists identifying that a specific deep neural network is being used for nearly all self-driving cars in the world (imagine if Tesla had a monopoly on the market and was the only self-driving car producer). From following video, we can see model the model get a bit "overfitted" on window and trash can. ®You can make almost any RC car self driving using the donkey library, but we recommend you build the Donkey2 which is a tested hardware and software setup.You can buy all the parts for ~$250 on Amazon and it takes ~2 hours to assemble. After setting up all software and hardware, Donkey Car provides user the ability to drive Donkey Car by using web browser and record all car status(images from front camera, angles and throttle value ). If the data quality is not good, even the good model can't get good performance. In the end, these attempts did not pan out and I never got an accuracy above 50% using convolution. you can find more details here. Learning from using opencv and Tensorflow to teach a car to drive. Visualization can help us get better idea what our model is doing and support us to debug the model. Ever since the thought and discussion and hype about self-driving cars came into existence, I always wanted to build one on my own. ... Use “Self Driving Car atan.ipynb” file for training the model. The system uses a Raspberry Pi with a camera and an ultrasonic sensor as inputs, a processing computer that handles steering, object recognition (stop sign and traffic light) and distance measurement, and an Arduino board for RC car control. Each time I pressed an arrow key, the car moved in that direction and it captured an image of the road in front of it, along with the direction I told it to move at that instance. Self-driving RC Car using Tensorflow and OpenCV. I attempted to add convolutional layers to the model to see if that would increase accuracy. Raspberry Pi collects inputs from a camera module and an ultrasonic sensor, and sends data to a computer wirelessly. I performed the Haar Cascade training on an AWS EC2 instance so that it would run faster and allow me to keep working on my laptop. Introduction Convenience. RC car chasis with motor and wheels I collected over 5,000 data points in this manner, which took about ten hours over the course of three days. so usually I collect data from both clock-wise can counterclockwise direction.
