Abstract: An unmanned aerial vehicle (UAV) system is disclosed. The UAV system includes a chassis, a plurality of propeller assemblies configured to provide vertical take-off and landing (VTOL) for the chassis with propulsion in 6 degrees of freedom including along a cartesian coordinate system (X, Y, Z) and provide yaw, pitch, and roll, the plurality of propeller assemblies are selected from the group consisting of (i) two fixed propeller assemblies and a tiltable propeller assembly, and (ii) four fixed propeller assemblies, a boom having a boom propeller assembly, configured to selectively provide positive and negative rectilinear thrust vectors, and an end-effector coupled to a distal end of the boom, the end-effector having a force sensor configured to provide contact force between the end-effector and an object.

Abstract: An unmanned ground-based system is disclosed which includes a chassis, a plurality of wheels coupled to the chassis and configured to allow the chassis to move about a surface, a plurality of propeller assemblies configured to provide on-ground motion propulsions, a boom having a boom propeller assembly with a propeller disposed on a plane generally perpendicular to the plurality of propeller assemblies, configured to independently and selectively provide positive and negative rectilinear thrust vectors, and an end-effector coupled to a distal end of the boom, the end-effector having a force sensor configured to provide contact force between the end-effector and an object, wherein the contact force is used as a feedback signal to determine magnitude of the positive and negative rectilinear thrust vectors that is generated by the propeller of the boom propeller assembly.
