Abstract:
A device and method for adjusting the magnetic strength of a magnetic end effector for lift systems is described. The magnetic end effector is capable of lifting discriminate payloads by selectively varying the strength of the magnetic forces output by the magnetic end effector. An actuator can be operatively coupled to the variable strength magnet end effector, wherein the actuator is selectively actuatable to control the adjustment of the variable strength magnet. The actuator may also be configured to maintain the variable strength magnet at a desired magnetic force output strength once achieved for any given amount of time.

Abstract:
An artificial finger assembly including articulating finger segments constructed of stacked and aligned plates. The finger segments are coupled to adjacent finger segment at common pivot points along a top edge of the assembly. The finger segments are caused to pivot around the common pivot points by a lever arm comprised of a series of articulated lever arm plates. The lever arm plates are coupled to the finger segments along an axis offset to one side of the common pivot points and parallel to the finger segments.
Abstract:
A medical device and method for manipulating movement of a micro-catheter, the device comprising an elongated tubular member having at least one lumen therein, wherein the lumen is proximally coupled to a pressurized fluid control system configured to regulate fluid flow through the elongated tubular member. An aperture is disposed near a distal end of the elongated tubular member, the aperture being in fluid communication with the at least one lumen. In one aspect, the aperture is oriented at an angle which is non parallel to the longitudinal axis of the elongated tubular member. A nozzle is coupled to the aperture, wherein the nozzle is configured to regulate pressurized flow out of the catheter to manipulate movement of the distal end of the elongated tubular member.
Abstract:
A liquid missile for being projected from a launching device which includes a liquid charge combined with a non-rigid flight integrity component. The flight integrity component allows the liquid charge to be launched at increased speeds and distances by inhibiting substantial break-up of the liquid charge during flight.
Abstract:
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.
Abstract:
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.
Abstract:
An amphibious robotic crawler for traversing a body of water having two frame units coupled end-to-end or in tandem by an actuated linkage arm. Each frame unit includes a housing with a drivable continuous track rotatably supported thereon. The frame units are operable with a power supply, a drive mechanism and a control module. Each frame unit further includes a buoyancy control element for suspending the frame unit in the water, and for controlling the depth of the robotic crawler within the water. The control module coordinates the rotation of the continuous tracks, the position of the linkage arm and the buoyancy of the buoyancy control elements to control movement, direction and pose of the robotic crawler through the body of water.
Abstract:
An operator controllable robotic device is disclosed. The robotic device comprises a support member, an upper robotic arm, a lower robotic arm, and a control arm. The upper robotic arm is coupled to the support member and has rotational movement in at least one degree of freedom relative to the support member. The lower robotic arm is coupled to the upper robotic arm and has rotational movement in at least one degree of freedom relative to the upper robotic arm. The control arm allows an operator to control the robotic device. The control arm is coupled to the upper robotic arm and has rotational movement in at least one degree of freedom relative to the upper robotic arm. The control arm allows a movement of the operator to control a movement of at least one of the upper robotic arm and the lower robotic arm.
Abstract:
A regenerative hydraulic pump that allows for efficient operation of a hydraulic system under high pressure/low flow conditions that comprises a crankshaft providing a rotating inertial mass, and a regenerative hydraulic pump cylinder that comprises a pump cylinder housing, a pump piston mechanically connected to the crankshaft; and a compliant pressure chamber that stores a portion of the energy extracted by the pump piston during a pumping stroke for release back to the pump piston and to the crankshaft during a regenerative back stroke.
