  • Patent number: 12330722
    Abstract: A multi-modal robot that is configured to operate with a bipedal locomotion that may be augmented with aerial locomotion. Many embodiments of a robot may incorporate a robot with a main body portion that houses the various control systems and mechanical controls of the robot. The body of the robot can have a number of different propellers connected to an upper portion of the body and configured to generate lift and/or stability for the body of the robot. Additionally, many embodiments have at least two leg elements connected to a bottom portion of the body by way of a servo mechanism. The legs are configured to provide support for the body of the robot as well as generate a walking locomotion through the movement of the legs.

  • Patent number: 11891170
    Abstract: An air transport vehicle that capitalizes on the strengths and complexities of a fixed and rotary winged aircraft. The air transport vehicle comprises a body aerodynamically designed to avoid substantial drag. The vehicle has a plurality of rotors configured to generate vertical thrust with a rear rotor configured to generate forward thrust. Additionally, each of the rotors are connected to the fixed wing elements and the fixed wing is positioned about the center of mass of the fuselage. Furthermore, each of the rotors are positioned at a fixed tilt angle such that the stability of the vehicle is maintained in a number of different flight configurations.

  • Patent number: 11733715
    Abstract: A fixed-wing vertical take-off and landing (VTOL) vehicle configured with a composite adaptive nonlinear tracking controller that utilizes a real-time accurate estimation of the complex aerodynamic forces surrounding the wing(s) and rotors in order to achieve a high performance flight. The method employs online adaptation of force models, and generates accurate estimation for wing and rotor forces in real-time based on information from a three-dimensional airflow sensor. The novel three-dimensional airflow sensor illustrates improved velocity tracking and force prediction during the transition stage from hover to forward flight.
