  • Patent number: 9440357
    Abstract: A system comprises a platform being configured for locomotion in a plurality of directions over a surface. A robotic unit is configured for dexterous manipulation comprising at least lifting of objects. The robotic unit is joined to the platform. At least one extender unit is joined to the platform and is configured for controlled extension beyond the platform to contact the surface to stabilize the system at least during the manipulation by the robotic unit. At least one controlling unit is configured to be operable for at least determining a center of gravity and a zero moment point for the system and for at least controlling an extension of the extender unit.

  • Publication number: 20150182403
    Abstract: Obesity has grown into one of the world's most significant health problems. The field of bariatrics and the quantity of bariatric surgical procedures is projected to continue to increase rapidly each year. This trend presents a challenge to healthcare providers and facilities striving to provide dignified care that is effective and safe both for the patient and the provider. There is a great demand for new approaches to bariatric patient care. The present invention is a robotic patient lifting system, targeted for, but not limited to, bariatric patient care. Without the need for difficult, time consuming slings and hoists associated with currently available systems, the invented lifting and transferring system utilizes rapidly deployable, articulated robotic arms with gentle conveyor belts. A unique linkage system allows powerful, safe, and flexible lifting and positioning of the patient with a minimal number of actuators.

  • Publication number: 20140150806
    Abstract: A robotic first responder system provides injured patients with first response medical care and extracts the injured patient from a dangerous or remote area. After assessing of the level of consciousness of an injured patient, the robotic unit utilizes an inflatable immobilization device for safe robotic rescue of injured patients. The robotic unit lifts and transfers an injured patient to an extraction vehicle, a secure, bullet-proof wheeled system that can be pulled by the robot to safe location. The extraction vehicle continues serving as the evacuation stretcher to a medical station. The robotic unit utilizes zero moment point control to maintain stability while lifting the patient. A robot first responder tows the extraction vehicle or the extraction vehicle self-navigates incorporating with power drive and autonomous navigation systems.

  • Publication number: 20140100491
    Abstract: To achieve “ecological” robotic rehabilitation therapy, the present invention provides the system capacity of training of patients in different ambulatory tasks utilizing motorized footplates that guide the lower limbs according to human gait trajectories generated for different ambulatory tasks of interest. A lower extremity robotic rehabilitation system comprises an active pelvic/hip device which applies series elastic actuation to achieve an intrinsically safe and desirable impedance control. A robotic unit features the telepresence operation control that allows a patient stay at home or nursing home to continue his or her rehabilitation training under a physician's remote supervision and monitoring.

  • Publication number: 20120283746
    Abstract: A medical robotic system comprises a drive track unit being operable for moving the medical robotic system along a floor. An upper torso unit is joined to the drive track unit. The upper torso unit comprises at least one actuator assembly. At least one bimanual dexterous manipulator is joined to the actuator assembly in which the actuator assembly imparts torque and movement to the bimanual dexterous manipulator for lifting an object. The bimanual dexterous manipulator comprises a pair of dexterous manipulators. Each of the dexterous manipulators comprises a length being configured to support lifting an adult patient, and an end comprising a planar structure being configured for placing between the adult patient and a patient platform. The drive track unit is operable for moving the medical robotic system to the patient platform and the bimanual dexterous manipulator is operable for lifting the adult patient from the patient platform.
