One or more embodiments of the invention generally relate to robots. More particularly, one or more embodiments of the invention relate to first responder robots, namely combat casualty evacuation and casualty care robots.
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.
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 guided by 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.
Typically, a first responder is a person who has completed a course and received certification in providing pre-hospital care for medical emergencies. The first responder may have more skill than someone who is trained in basic first aid but is typically not a substitute for advanced medical care rendered by emergency medical technicians, emergency physicians, nurses, or paramedics.
Typically, the use of stabilization techniques improves the chances of a person surviving the transport to the nearest trauma-equipped hospital. After ensuring their own safety and taking isolation precautions, a primary survey is performed, consisting of checking and treating airway, breathing, and circulation, then an assessment of the level of consciousness. To prevent further injury, unnecessary movement of the spine is minimized by securing the neck with a cervical collar, and the back with a long spine board with head supports, or other medical transport device such as a Kendrick extrication device, before moving the person.
In view of the foregoing, it is clear that these traditional techniques are not perfect and leave room for more optimal approaches.
The present invention is illustrated by way of example, and not by way of limitation, in the figures of the accompanying drawings and in which like reference numerals refer to similar elements and in which:
Unless otherwise indicated illustrations in the figures are not necessarily drawn to scale.
Embodiments of the present invention are best understood by reference to the detailed figures and description set forth herein.

For example, it should be appreciated that those skilled in the art will, in light of the teachings of the present invention, recognize a multiplicity of alternate and suitable approaches, depending upon the needs of the particular application, to implement the functionality of any given detail described herein, beyond the particular implementation choices in the following embodiments described and shown. That is, there are numerous modifications and variations of the invention that are too numerous to be listed but that all fit within the scope of the invention. Also, singular words should be read as plural and vice versa and masculine as feminine and vice versa, where appropriate, and alternative embodiments do not necessarily imply that the two are mutually exclusive.
It is to be further understood that the present invention is not limited to the particular methodology, compounds, materials, manufacturing techniques, uses, and applications, described herein, as these may vary. It is also to be understood that the terminology used herein is used for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present invention. It must be noted that as used herein and in the appended claims, the singular forms “a,” “an,” and “the” include the plural reference unless the context clearly dictates otherwise.
