  "description_excerpt": "The present subject matter relates generally to robotic systems and methods for vehicle fueling and charging. More particularly, the present subject matter relates to a robotic system for fueling or charging a vehicle in an autonomous fashion.\n\nMany vehicles in use today operate on a finite energy source such as a fossil fuel or an electrical charge stored on board the vehicle. As such, these vehicles require periodic replenishment of their stored supply of fuel or electrical charge. Replenishment typically requires parking the vehicle in proximity to a source of fuel or electric current for a predetermined amount of time sufficient to replenish the vehicle's energy source. Replenishment also typically requires establishing a connection between a receptacle in or on the vehicle and a conduit capable of delivering fuel or electrical current to the vehicle. This is typically a manual process requiring human intervention, as well as some familiarity with both the vehicle and with the available replenishment equipment. The replenishment operation can give rise to certain hazards, such as a loss of connectivity and spillage or fluid or electrical arcing, incorrect selection of fueling or charging equipment, and inadvertent movement of the vehicle during replenishment.\n\nAccordingly, there remains a need for improved systems and methods of fueling and charging vehicles which deliver enhanced safety, reliability, and ease of use.",
