Autonomous vehicles are able to drive themselves without human supervision or input. Vehicles can also operate semi-autonomously - taking some control of aspects of driving, whilst a human driver retains control of others. In order to do this, the vehicle must be able to perceive its environment and make decisions about where it is safe and desirable to move, and do so. This session will go through various aspects of the algorithms for sensor fusion to build perception, map building and path planning with particular reference to the Blue Box development platform.
