摘要： The present invention relates to a new pneumatic-actuated multifunctional doming actuator. The doming actuator can be used as a doming actuator, which can maintain machine/robotic operation on vertical surfaces without falling. The doming actuators exhibit rapid switchable adhesion/deadhesion on target surfaces upon pressurizing/depressurizing the embedded spiral pneumatic channels. The present invention also relates to novel load-carrying and climbing soft robots using the doming actuators. The soft robots are operable on a wide range of horizontal and vertical surfaces including dry, wet, slippery, smooth, and semi-smooth surfaces. In addition, the doming actuators can be used as a driving actuator for swimming soft robotics and as an actuator for soft grippers.

摘要： A brake cylinder includes a brake cylinder housing having a master chamber, a slave chamber, and a wall disposed there between. The wall defines at least one opening configured to provide fluid communication between the master chamber and the slave chamber. The brake cylinder also includes a master piston configured to pressurize fluid in the master chamber when a brake pedal is pressed. The brake cylinder further includes a slave piston and a pressure sensor disposed in fluid communication with the slave chamber. The pressure sensor is configured to measure pressure in the slave chamber and send a signal to a processor indicating of movement of the brake pedal. When pressurizing fluid in the master chamber, the master piston is configured to drive fluid from the master chamber to the slave chamber via the at least one opening to increase pressure in the slave chamber.

摘要： A hydraulic lockout lever failure detection system preferably includes a first analog sensor, a second analog sensor, at least one electronic control module (ECU) and a solenoid valve. The voltage output level of the first and second analog sensors is monitored by the ECU. The solenoid valve controls the flow of hydraulic fluid to operate an excavator or other equipment. The operation of the solenoid valve is controlled by the ECU. However, a second ECU may be used to control the operation of the solenoid valve. A hydraulic lockout lever causes the first and second analog sensors to output either a low voltage to indicate a closed position, or to indicate an open position to the ECU. If the first and second analog sensors output a voltage that is above a low set value or above a high set value, a fault is detected.

摘要： A hydraulic circuit is disclosed. The hydraulic circuit may include a hydrostatic pump to provide, at a flow rate, a fluid to a hydraulic motor, wherein the hydrostatic pump has a displacement, and wherein the hydraulic motor drives a swinging element; a swing circuit pressure sensor to sense a circuit pressure of the hydraulic circuit; a pilot pressure actuator to control, based on a supply pressure, the displacement of the hydrostatic pump; a pilot pressure override valve to control the supply pressure; and a controller configured to adjust, based on sensed signals and with the pilot pressure override valve, the supply pressure, wherein the sensed signals include: a circuit pressure signal based on the circuit pressure sensed by the swing circuit pressure sensor; and a sensed swing speed signal based on a swing speed of the swinging element sensed by one or more machine sensors.

摘要： An actuator includes first and second ends defining an axis there between, and at least four inflatable chambers. Each inflatable chamber is resiliently deformable, elongate, and extends axially between the first and second ends and circumferentially about a central core defined between the ends and by the inflatable chambers. A first pair of the four inflatable chambers is contra rotatory about the core to a second pair of the four inflatable chambers. A pressure change in one or more of the inflatable chambers causes motion of the first end relative to the second end. The actuators can be employed in robots or robotic arms.

摘要： A hydraulic machine is provided. A first flow control valve directs fluid from a first fluid supply to a first actuator when the first flow control valve is in a first position. A conflux control valve directs fluid from the first fluid supply to a second flow control valve when the conflux control valve is in a conflux position. The second flow control valve directs fluid from a second fluid supply and the first fluid supply to a second actuator when second flow control valve is in a second position. A bypass path allows the first fluid supply to communicate with the conflux control valve by passing around the first flow control valve.
