Abstract: Apparatus are provided for automatic repositioning of fluid nozzles when operating on a workpiece with a tool. The apparatus includes a nozzle assembly configured to convey a fluid to a target zone defined on the workpiece and/or on the tool. The target zone has a location that varies over time. A spring applies a spring force to bias the nozzle assembly toward the target zone, and moves the nozzle assembly as the location of the target zone varies. The nozzle assembly moves to a position relative to the target zone by a combination of action of the spring force and of any hydrodynamic force of the fluid, when moving through the nozzle assembly.

Abstract: Various technologies described herein pertain to controlling an autonomous vehicle to provide indicators to distinguish the autonomous vehicle from other autonomous vehicles in a fleet. The autonomous vehicle includes a vehicle propulsion system, a braking system, a notification system, and a computing system. The notification system outputs an indicator that is perceivable external to the autonomous vehicle. The computing system receives data specifying an identity of a passenger to be picked up by the autonomous vehicle. Moreover, the computing system controls at least one of the vehicle propulsion system or the braking system to stop the autonomous vehicle for passenger pickup. Further, the computing system controls the notification system to output the indicator; a characteristic of the indicator outputted by the notification system is controlled based on the identity of the passenger to be picked up and whether the autonomous vehicle is stopped for passenger pickup.
