    Abstract: This invention is regarding a set of stand-alone or combined-use surgical tools and associated systems and methods for performing surgical procedures such as identifying hidden tissue anatomy and dissecting the periphery tissues. In particular, this invention describes tools and the associated systems and methods for visualizing hidden important structures such as arteries, veins, ureters, bile duct, bowel, nodules, tumors, and performing tissue cutting using energy-based instrument. The tools are to be operated stand-alone or by attaching to existing instruments used for minimally invasive surgery.

    Abstract: An embodiment of the present disclosure relates to an unmanned flying robotic object that contains a wheeled mechanism that encircles its spherical exoskeleton. This feature allows the flying spherical vehicle to readily transform into a ground maneuverable vehicle. A robotic motor with differential speed capability is used to operate each wheel to provide effective ground maneuverability. There are examples provided herein of wheel configurations suitable for use with an embodiment. One is the straight-(or parallel) wheel design, and another is tilted-wheel design as are illustrated and discussed hereinafter. One embodiment of an unmanned flying robotic object taught herein is foldable.
