The present invention provides a micro-robot for use inside the body during minimally-invasive surgery. The micro-robot may include various sensors, imaging devices or manipulators.

The present invention relates to magnetically coupleable robotic surgical devices. More specifically, the present invention relates to robotic surgical devices that can be inserted into a patient's body and can be positioned within the patient's body using an external magnet.

Systems and methods for transferring a micro device from a carrier substrate are disclosed. In an embodiment, a mass transfer tool manipulator assembly allows active alignment between an array of electrostatic transfer heads on a micro pick up array and an array of micro devices on a carrier substrate. Displacement of a compliant element of the mass transfer tool manipulator assembly may be sensed to control alignment between the array of electrostatic transfer heads and the array of micro devices.

The present invention provides a robot for use inside an open abdominal cavity during minimally-invasive surgery. The robot may include various sensors, imaging devices or manipulators.

The present invention is a miniature camera robot which can be placed entirely within an open space such as an abdominal cavity. The instant camera robot has pan and tilt capabilities, an adjustable focus camera, and a support means for supporting the robot body. In particular embodiments, the camera robot further contains a light source for illumination and a handle to position the camera robot. A system and method for using the instant camera robot are also provided.

Disclosed are systems and methods for manipulating chemical, biological, and / or biochemical samples, optionally supported on substrates and / or within chambers, for example biological samples contained on chips, within biological chambers, etc. In certain embodiments, an apparatus configured to be able to position a chamber or other substrate in one or more modules surrounding the apparatus is disclosed. The apparatus may be configured to be able to move the chamber or substrate in any set of directions, such as radially, vertically, and / or rotationally, with respect to the apparatus. The apparatus may be manually operated and / or automatically controlled. Examples of modules include, but are not limited to, stacking or holding modules, barcode readers, filling modules, sampling modules, incubation modules, sensor modules (e.g., for determining cell density, cell viability, pH, oxygen concentration, nutrient concentration, fluorescence measurements, etc.), assay modules (e.g., for ELISA or other biological assays), data analysis and management modules, control modules, etc. Sensors, control systems, and the like may also be positioned to facilitate operation of the device. Certain embodiments of the invention may be used, for example, to promote or optimize chemical synthesis or cell or biological growth, for instance, for the production of compounds such as drugs or other therapeutics.

A manipulator comprises an operation command unit provided with an attitude adjusting unit and an end effector control unit, a connecting unit having one end connected to the operation command unit, a working unit connected to the other end of the connecting unit and provided with an end effector and a support unit supporting the end effector for motions, and a control unit that transmits an operation command provided by the attitude adjusting unit to the support unit to adjust the attitude of the end effector and transmits an operation command provided by the end effector control unit to the end effector to operate the end effector. The support unit includes a first joint capable of turning about a first axis perpendicular to the center axis of the connecting unit, and a second joint capable of turning about a second axis perpendicular to the first axis. The end effector can be turned for rolling about an axis substantially parallel to the second axis of the second joint. The attitude adjusting unit has a third joint having a third axis perpendicular to the center line of the connecting unit. The end effector control unit is formed such that the fingers of an operator gripping operating members included in the end effector control unit extend substantially in parallel to the fourth axis.

A hydraulically-operated micromanipulator apparatus is disclosed. The micromanipulator apparatus comprises: a micromanipulator fine control unit including an operating-side piston finely movable with respect to an operating-side hydraulic cylinder and fine control means, either the operating-side piston or the operating-side hydraulic cylinder being stationarily retained, while the rest being finely operable by the fine control means; a hydraulically-operated micromanipulator including an actuating-side piston finely movable with respect to an actuating-side hydraulic cylinder and a fine displacement member, the actuating-side hydraulic cylinder being connected to said operating-side hydraulic cylinder through a hose, either the actuating-side piston or the actuating-side hydraulic cylinder being stationarily retained, while the rest being attached to the fine displacement member; and compensating means for compensating a pressure change of the hydraulic fluid between said operating-side hydraulic cylinder and said actuating-side hydraulic cylinder when ambient temperature changes.

An improved human motion applicator assures a quick and sufficient amount of displacement given to a part of a human body. The applicator includes a support adapted to be fitted on the part of the human body. The support carries at least one electro-active elastic actuator in a force-transmitting relation to the human part. The actuator includes a dielectric core and a pair of electrodes on opposite of the core for receiving a driving DC voltage thereacross. The elastic actuator has a length and elastically deforms in the lengthwise direction to exert a stretching force to the human part to a greater extent as the driving DC voltage increase. The applicator also includes a controller which applies the driving DC voltage of varying levels to the elastic actuator, thereby generating a varying motion-inducing force to be applied to the part of the human body.

Systems and methods for transferring a micro device from a carrier substrate include, in an embodiment, a micro pick up array structure to allow the micro pick up array to automatically align with the carrier substrate. Deflection of the micro pick up array may be detected to control further movement of the micro pick up array.
