FIELD OF THE INVENTION

[0005] One or more embodiments of the invention generally relate to robots. More particularly, one or more embodiments of the invention relate to medical robots.

BACKGROUND OF THE INVENTION

[0006] The following background information may present examples of specific aspects of the prior art (e.g., without limitation, approaches, facts, or common wisdom) that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon.

[0007] The following is an example of a specific aspect in the prior art that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon. By way of educational background, another aspect of the prior art generally useful to be aware of is that a robot is a mechanical or virtual intelligent agent that can perform tasks automatically or with guidance, typically by remote control. In practice a robot is usually an electro-mechanical machine that is controlled by means of computer and electronic programming. By mimicking a lifelike appearance or automating movements, a robot may convey a sense that it has intent or agency of its own. More importantly, a robot working with nurse and supporting patient should be also have an intrinsically safe actuation and being able to cooperate with human safely which is significantly different from those industrial robots constrained in a protected area.

[0008] Typically, a wide range of mechanical lifting and transfer solutions have evolved to enable safe patient lifting and handling.

[0009] Typically, one can expect that the aging population will require greater medical assistance, which may result in inadequate health services. The human workforce does not have the same capacity to service the aging population as a robotic device would. The time and effort needed are great.

[0010] In view of the foregoing, it is clear that these traditional techniques are not perfect and leave room for more optimal approaches.

Those skilled in the art, in light of the present teachings, will recognize that to ensure that medical robotic system does not drop the object if a power failure occurs, actuator assembly must be non-backdriveable. This requirement may be met by utilizing a worm drive gear and harmonic drive system.

[0044] FIG. 4b illustrates a blow up view of actuator assembly that powers bimanual dexterous manipulator, in accordance with an embodiment of the present invention. In the present embodiment, actuator assembly may comprise of a motor for transferring torque to a gear box. Actuator assembly utilizes components of elastic materials and properties to provide enhanced torque in a limited area. An output shaft drives the manipulator joint, and includes a multiplicity of torsional springs. In the present embodiment, torsional springs utilize urethane rods to provide large torque in a small area. The urethane rods may be positioned in matched grooves in the actuator assembly housing and output shaft. Relative angular motion between assembly housing and output shaft acts to deform the urethane, creating high torsional spring rates in minimal space.

[0045] FIG. 4c illustrates a sectioned view of actuator assembly that moves the bimanual dexterous manipulators, in accordance with an embodiment of the present invention. In the embodiment shown, torso may include a modular structure composed of three actuator assemblies attached to each other. Those skilled in the art will recognize that designing in this way may simplify the manufacturing process and allow for quick and easy repairs.

Attaching the third actuator at a right angle completes the 3-degree of freedom upper arm.

[0046] FIGS. 4d and 4e illustrate an exemplary output shaft, where FIG. 4d illustrates a blow up view of output shaft, and FIG. 4e illustrates a side view of three separate sets of torsional springs positioned in three separate output shafts, in accordance with an embodiment of the present invention. In some embodiments, torsional springs work in unison to provide sufficient torque. Those skilled in the art will recognize that actuator assembly should be a self-contained actuator, capable of continuous rotation.

[0047] FIG. 5 illustrates an exemplary upper torso that attaches to dexterous manipulator and receives an interface, in accordance with an embodiment of the present invention. In the embodiment shown, upper torso may resemble a human torso to increase functions and to comfort patient. Upper torso may be capable of advanced dexterous manipulation and patient lifting, haptic feedback and natural human-robot interaction.

Those skilled in the art, in light of the present teachings, recognize that an advanced human robot interaction module is a key component of medical robotic system. An efficient human-robot interaction module that supports effective direct control and cooperative operation procedures. In a yet another embodiment, medical robotic system utilizes a direct human-robot interaction system. The direct human-robot interaction system may adopt a human-in-the-loop robot control scheme--either under direct commands or in telepresence operation. In some embodiments, the present invention may be used for nursing at hospitals as a nurse assistant or serves as remote service provider at nursing home.

[0049] FIGS. 6a and 6b illustrates a detailed perspective view of an exemplary robotic mobile platform that provides an enhanced stability with zero moment point extender for the medical robotic system, in accordance with an embodiment of the present invention, where FIG. 6a provides a mobile platform for movement of the medical robotic system, and FIG. 6b expands to provide a wide base for stability for the medical robotic system. In the present embodiment, drive track provides a foundation for the medical robotic system. By expanding the dimensions of drive track, a larger foundation for drive track creates increased stability for medical robotic system. This may be beneficial for supporting heavy objects. In yet another embodiment, robotic drive track utilizes zero moment point control for enhanced stability. Zero moment point specifies a point with respect to a dynamic reaction force at the contact of the drive train with the ground does not produce any moment in the horizontal direction, i.e. the point where total of vertical inertia and gravity forces equals zero. In the present embodiments, it is this point that may produce the greatest stability, and medical robotic system may intelligently recognize this point.

[0050] In some embodiments, robotic drive track may navigate intelligently through a medical facility, including without limit tight spaces in proximity to a bed, with unique perceptive software and a holonomic drive. Those skilled in the art, in light of the present teachings, will recognize that a holonomic drive is useful for situations requiring higher mobility and lower traction than a standard drive system. The holonomic drive allows drive track to translate in any direction, independent of rotation. This movement may utilize, without limitation, omni-wheels or mecanum wheels.

[0051] FIG. 7 illustrates an exemplary navigation control system on mobile medical robotic system that traverses through a medical facility, in accordance with an embodiment of the present invention. In the present embodiment, navigation control system may be remotely controlled by health care professional. Navigation control system utilizes intelligent software for sensing, perception, obstacle avoidance, and semi autonomy. Those skilled in the art, in light of the present teachings, recognize that high performance navigation control in a humanoid world like a hospital environment requires advanced sensory perception and intelligent control/decision to ensure system and operation safety. Specifically, the ability to detect a moving object in real-time is crucial and unique to system safety.

[0052] In the present embodiment, nurse directs the anthropomorphic, omni-directional robot by moving the robot's compliant arms and applying forces to the robot's hands to guide a robot during navigation around a cluttered bed and placement of its arms underneath a patient.

[0053] In some alternative embodiments, medical robotic system may utilize speech recognition software to recognize patient, or identify patient in distress. Medical robotic system may also speak to patient in a soothing human voice to alleviate trepidation from patient. In yet another alternative embodiment, dexterous manipulators perform patient monitoring and medicine delivery through direction from a remote health professional.

[0054] In some alternative embodiments, medical robotic system may be powered by electric fully or partially, by pneumatic fully or partially, by hydraulic fully or partially or other power forms.

[0055] All the features or embodiment components disclosed in this specification, including any accompanying abstract and drawings, unless expressly stated otherwise, may be replaced by alternative features or components serving the same, equivalent or similar purpose as known by those skilled in the art to achieve the same, equivalent, suitable, or similar results by such alternative feature(s) or component(s) providing a similar function by virtue of their having known suitable properties for the intended purpose. Thus, unless expressly stated otherwise, each feature disclosed is one example only of a generic series of equivalent, or suitable, or similar features known or knowable to those skilled in the art without requiring undue experimentation.

[0056] Having fully described at least one embodiment of the present invention, other equivalent or alternative methods of implementing medical services to patients in a health care facility through a medical robot according to the present invention will be apparent to those skilled in the art. Various aspects of the invention have been described above by way of illustration, and the specific embodiments disclosed are not intended to limit the invention to the particular forms disclosed.
