SINTEF Self-Driving Truck w/induction charger

This repository contains code for a self-driving smallscale truck with wireless inductive charging. It is part of a master thesis in cybernetics and robotics at NTNU 2019, and contains code for three different path following methods: - SLAM with Pure Pursuit (and Stanley steering) steering controller - Supervised Deep Learning steering controller with OpenCV - Lane Detector with steering controller (PID) and OpenCV

The system is based on Ubuntu 16.04 with ROS Kinetic running on a Nvidia Jetson TX2. The truck itself is controlled by a Teensy 3.2 microcontroller. Other components used are the RPlidar A2M8 lidar and the Logitech C922 webcam.

Start-up

To start the autonomous system, type:

sh
$ roslaunch car_cmd run.launch
