Self-Driving Software + Carla Simulator

Want to learn more about self-driving car simulators? Check out this blog post. Simulators are crucial in developing a good self-driving system. Not everyone will have access to quality self-driving hardware platforms, therefore software simulator is a nature incubator for cutting-edge research and development.

GPS Localization with ROS, rviz and OSM

When you place a robot in a known environment, the robot should be able to localize itself, meaning it could compute the approximate position of itself using sensors and algorithms. Localization is crucial to self-driving vehicles, which requires incredible precision. GPS (Global Positioning System) is one of the first steps to localization. However, the system is… Continue reading GPS Localization with ROS, rviz and OSM

Visualizing Open Street Map Data with ROS & rviz

Localization and path planning are two of the most important components in autonomous robots. Robot Operating System provides a great foundation for working with maps and path planning. In this post, I will talk about how to use data provided by Open Street Map (OSM) and to visualize the osm data using rviz. I still… Continue reading Visualizing Open Street Map Data with ROS & rviz

Migrating to ROS — Hello, Robot Operating System

Our goal has always been to create the best autonomous driving software possible on a small scale. A critical component of that goal is to write conventional code and use industry standard libraries. This is one of the reasons why I am working on integrating ROS into the self-driving golf cart. Once the project is fully… Continue reading Migrating to ROS — Hello, Robot Operating System

Building a Cargo Box for the Golf Cart (Part 2)

Introduction This is part 2 of the two parts series of how we built a cargo box for the golf cart. If you haven't seen part 1, it's right here! In part two, I will mainly talk about how I mounted the cargo box on the golf cart. Pictures Here are some pictures of the… Continue reading Building a Cargo Box for the Golf Cart (Part 2)

Building a Cargo Box for the Golf Cart (Part 1)

Introduction After I purchased the new computer for the golf cart, I have been looking for a place to put the computer and batteries. I drew inspirations from other projects and other golf carts, and eventually landed on this plan: build a wooden cargo box. Here is an example of a cargo box for a… Continue reading Building a Cargo Box for the Golf Cart (Part 1)

Visualizing the Steering Model with Attention Maps

Introduction Convolutional neural networks are often known as "black boxes" for their mysterious nature. Unlike most programs that we write, computer scientist can't directly modify the content (weights) of the neural networks to improve their performance. In order to create better machine learning models, you can either do a heck more training or experiments with… Continue reading Visualizing the Steering Model with Attention Maps

Building a New Computer for the Golf Cart

Introduction In the past week or so, I have been building and setting up a new computer for the golf cart. Now, this new machine is fully set up and ready to go. Next week, I will finish building a cargo box on the back of the golf cart where the computer will be placed.… Continue reading Building a New Computer for the Golf Cart

The Limitations Of Our Deep Learning Powered Self-Driving Golf Cart

Introduction After our somewhat unsuccessful demo last Wednesday, my partner Michael Meng exclaimed, "there is no hope for deep learning". The future is not that grim, but Michael is right to a certain degree. Deep learning has flaws and our deep learning powered self-driving golf cart certainly has lots of flaws. Today, I would like to… Continue reading The Limitations Of Our Deep Learning Powered Self-Driving Golf Cart
