Autonomous Vehicle Lab: 2D Top-Down Driving

What Autonomous Vehicle Lab Is

The Autonomous Vehicle Lab is an interactive simulation that models the behavior of autonomous vehicles in a simplified 2D environment. It showcases how these vehicles use various sensors like radar, lidar, and cameras to gather data about their surroundings, which is then processed by advanced algorithms such as Kalman filters to make decisions.

In this lab, you can observe how an autonomous vehicle adjusts its speed, follows traffic rules, and responds to dynamic elements like pedestrians. The simulation also allows users to take control manually, providing a hands-on experience of the challenges involved in autonomous driving.

How It Works

The lab employs sensor fusion techniques where data from multiple sensors are combined to provide a more accurate and reliable picture of the vehicle's environment. For instance, radar measures distances accurately but may struggle with detecting smaller objects or in cluttered environments, while lidar can detect obstacles precisely but is affected by weather conditions. Cameras offer detailed visual information but require sophisticated image processing.

The Kalman filter used in this lab helps in estimating the state of the vehicle and its surroundings more accurately by combining measurements from different sensors and accounting for uncertainties. This process ensures that the autonomous vehicle can make informed decisions, such as adjusting speed to maintain a safe distance or braking when necessary.
