Our requirements encompass the features of autonomous vehicles with an ability to perform evasive maneuvers. The robot must be able to perceive its environment and know its state within it. It must be able to navigate from point to point in the environment, and do so reliably without hitting obstacles or going unstable. On top of these standard requirements, our project also requires the robot to be capable of advanced evasive maneuvers, while remaining stable.<\/p>\n
