I started a very new job working with Autonomous Vehicles but don't know much about them.
self-driving car, robotic car) and unmanned ground vehicle is a vehicle that is capable of sensing its environment 
How does it actually work? Does a robot drive it?
Robotics is an interdisciplinary branch of engineering and science that includes mechanical engineering, electrical engineering, 
Does the car use sensors or camera's to see where its going?
Digital single-lens reflex camera
A digital single-lens reflex camera (digital SLR or DSLR) is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film. The reflex design scheme is the primary difference between a DSLR and other digital cameras. In the reflex design, light travels through the lens, then to a mirror that alternates to send the image to either the viewfinder or the image sensor. The traditional alternative would
Self-driving car
A self-driving car, also known as an autonomous car, driverless car, or robotic car, is a vehicle that is capable of sensing its environment and moving safely with little or no human input.
Self-driving cars combine a variety of sensors to perceive their surroundings, such as radar, lidar, sonar, GPS, odometry and inertial measurement units. Advanced control systems interpret sensory information to identify appropriate navigation paths, as well as obstacles and relevant signage.
