摘要:
A method of configuring a biomimetic mechanical joint for the efficient movement of a support member about a pivot device. The method includes providing a first fractional actuator and a second fractional actuator being operable with the support member and the pivot device, sizing the first fractional actuator for rated operation at a first boundary condition, and sizing the second fractional actuator so that the first and second fractional actuators, when recruited in combination, are rated for operation at a second boundary condition.
摘要:
A biomimetic mechanical joint for generating a variable torque between support members of a biomimetic robotic device, including a base support member, a rotary support member rotatably coupled to the base support member, and a variable-radius pulley operably coupled between the base support member and rotary support member. The variable-radius pulley comprises a sheave body having a variable radius and one or more tendon grooves formed in the circumferential outer surface. The mechanical joint further includes one or more flexible tendons and antagonistic actuator pairs, with each actuator pair being coupled to one or more tendons and configured to operate the tendon around the variable-radius pulley in either direction to create a variable torque between the base and rotary support members.
摘要:
A method of operating a biomimetic mechanical joint having a plurality of fractional actuators configured for rotating a support member about a pivot device. The fractional actuators can be selectively recruited during operation, either individually or together, to efficiently rotate the support member about the mechanical joint throughout a range of movements and under a variety of load conditions. Each fractional actuator can be continuously throttled to reduce the speed or torque at which the actuator operates. The capability of selectively recruiting and throttling each fractional actuator results in an actuator system having two degrees of freedom, in which a single operating state of the mechanical joint may be reached with one or more of actuator arrangements and throttling settings. The method of the present invention allows for selection from the available actuator arrangements and throttle settings according to predetermined operating modes such as high-efficiency, high-acceleration or general-purpose, etc.

A remote operator console provides point and go navigation of a robotic vehicle. The remote operator console provides a display for visual representation of the environment in which the robotic vehicle is operating based on sensor information received from the robotic vehicle. An operator may designate a target point on the display. The robotic vehicle is automatically navigated toward a location in the environment corresponding to the designated target point.

An electro-spray delivery device for delivering a stream of charged micro-droplets of a conductive fluid, and which a capillary tube having a proximal end in fluid communication with a source of conductive fluid and a distal end opposite the proximal end. The device also includes a solid guide wire coaxially disposed at least partially within the capillary tube to form an annular passage therein, and which has a distal tip projecting beyond the distal end of the capillary tube. At least one of the capillary tube and guide wire is conductive and in electrical communication with a high-voltage source to electrically charge the conductive fluid flowing through the annular passage and wetting the distal tip of the guide wire. The electrospray delivery device further includes a grounding electrode that is located a predetermined distance from the distal tip of the guide wire and which is in electrical communication with a source of ground. A voltage differential between the charged fluid and the grounding electrode draws the charged fluid away from the distal end of the capillary tube to form a cone jet about the end face of the distal tip discharging a stream of charged micro-droplets.

An electrospray dispensing system for delivering a controllable quantity of charged micro-droplets of a conductive fluid, and which includes an elongate fluid supply cylinder having a first end, a second end, a sidewall (e.g., forming a circular or other polygonal cross-section) between the first and second ends, and an interior hollow that is in fluid communication with a source of conductive fluid. The dispensing system also includes an array of selectively-activated capillary tubes having proximal ends that are in fluid communication with the interior hollow and distal ends extending radially outward through the sidewall, and which are configured so that any conductive fluid flowing outwardly through one or more activated capillary tubes is electrically-charged. The dispensing system further includes a grounding electrode that is in electrical communication with a source of ground and located at a predetermined distance from the distal ends of the capillary tubes, so that an electric potential between the charged conductive fluid and the grounding electrode will cause each of the activated capillary tubes to form a cone jet which projects a stream of charged micro-droplets towards the grounding electrode.

The present invention relates to a single-target-specific fire fighting device for launching a liquid charge towards a localized target portion of a fire. The firefighting device is capable of highly precise target engagement at a single, localized area. In this manner, the fire fighting device can launch a single liquid charge effectively to a target location within a fire, such as the seat of a fire, in order to effectively extinguish the fire. The firefighting device includes at least a liquid charge having a flight integrity component, a barrel, a sighting structure coupled to the barrel, and a launching system for launching the liquid charge down the barrel at a target location.

A teleoperated robotic system that includes master control arms, slave arms, and a mobile platform. In use, a user manipulates the master control arms to control movement of the slave arms. The teleoperated robotic system can include two master control arms and two slave arms. The master control arms and the slave arms can be mounted on the platform. The platform can provide support for the master control arms and for a teleoperator, or user, of the robotic system. Thus, a mobile platform can allow the robotic system to be moved from place to place to locate the slave arms in a position for use. Additionally, the user can be positioned on the platform, such that the user can see and hear, directly, the slave arms and the workspace in which the slave arms operate.
摘要:
A method for controlling a tele-operated robot agile lift system is disclosed. The method comprises manipulating a human-machine interface of a master robot located on a mobile platform. The human machine interface is kinematically equivalent to a user's arm with a plurality of support members. A position value and a torque value is measured for each support member. The position value and torque value are communicated to support members of a kinematically equivalent slave arm to position the support members to correspond with a position of the human-machine interface.
