A solenoid valve in a manifold is commanded to move to a closed position. Upon activating a pump to supply fluid to the manifold via a supply line, a first pressure is determined in the supply line after commanding the solenoid valve to move to the closed position. Upon deactivating the pump to stop supplying fluid to the manifold, a second pressure is determined in the supply line. Based on a difference between the first pressure and the second pressure, the solenoid valve is determined to be one of (a) at least partially open or (b) in the closed position.

In embodiments, the sunblock lotion spray booth comprises a booth, a plurality of spray columns, a plurality of canisters, a pump, a ventilator, and one or more payment receiving devices. The booth may be adapted to spray one or more tanning products onto a user via the plurality of spray columns located within the booth once a payment receiving device and an activation button have been activated. As non-limiting examples, the one or more tanning products may be sunblock lotions having different SPF values, bronzers, or combinations thereof. One or more of the plurality of spray columns may be height-adjustable. The pump may move the tanning products from the plurality of canisters to a plurality of nozzles located on the spray columns via tubing within the walls of the booth. The ventilator may circulate air within the booth.

A coating device has a coating head that dispenses coating material toward a vehicle body. The coating device also includes a supply device that has a circulation path for circulating the coating material between a reservoir storing the coating material and the coating head, and is capable of controlling the pressure of the coating material flowing through the circulation path. The coating device includes an arm having the coating head and the supply device, wherein the coating robot performs coating of the vehicle body while moving the coating head wherein the coating head moves at a first speed toward a coating start position to start coating the vehicle and moves at a second speed different from the first speed when it reaches a specific position in a movement path to the coating start position.

An electrostatic cleaning device includes: a flying portion having a body, at least one power source, at least one extension extending from the body, defining a hollow interior, at least one propeller configured to generate lift for the electrostatic cleaning device located at an end of the at least one extension, and at least one electrical connection extending through the hollow interior, connecting the power source to the propeller. An associated spray system includes a tank mounted to the flying portion and configured to store a cleaning spray, at least one spray mechanism in fluid communication with the tank to discharge the cleaning spray, and at least one electrostatic generating unit configured to apply a voltage across a spray path of the cleaning spray, so that the spray is electrostatically charged. At least a portion of the at least one extension is coated or shielded by nanotube particles.

A next generation painting robot with advanced fluid delivery system, enhanced kinematics and a service airlock compartment. The painting robot includes a fluid delivery system which places color changing valves and pumping hardware on the back side of the robot's mounting pedestal, where it can be serviced without a technician having to enter the spray booth. The fluid delivery system also allows smaller and lighter robot arms, and is designed to minimize paint waste and wait time during color changes. The robot also features kinematics providing redundant inner arm rotation. The arm kinematics, along with the smaller arms, a paint supply line routed through the center of first and third arm joints, and optimized motor conductor routing, dramatically improve near reach flexibility. The improved near reach flexibility in turn allows a smaller spray booth than possible with previous robot architectures.
