Abstract: Vertical take off and landing unmanned aerial vehicle (UAV) comprising a multi-propeller propulsion system (“the system”), an outer protective cage surrounding the system, an autonomous power source, a sensing system, and a control system. The sensing system has an orientation sensor and a displacement sensor. The system has at least two propellers spaced apart in a non-coaxial manner. The control system controls the flight or hovering of the UAV. The control system reverses thrust on at least one propeller distal from a point of contact with an obstacle while controlling a motor of a proximal propeller from the contact point to generate lift, the thrust of the distal and proximal propellers being controlled to exert lift on the UAV to counteract gravitational force thereon and apply a moment of rotation about said point of contact to stabilize the position of the UAV or to counteract torque resulting from inertia.

Abstract: A new method for the estimation of ego-motion (the direction and amplitude of the velocity) of a mobile device comprising optic-flow and inertial sensors (hereinafter the apparatus). The velocity is expressed in the apparatus's reference frame, which is moving with the apparatus. The method relies on short-term inertial navigation and the direction of the translational optic-flow in order to estimate ego-motion, defined as the velocity estimate (that describes the speed amplitude and the direction of motion). A key characteristic of the invention is the use of optic-flow without the need for any kind of feature tracking. Moreover, the algorithm uses the direction of the optic-flow and does not need the amplitude, thanks to the fact that the scale of the velocity is solved by the use of inertial navigation and changes in direction of the apparatus.
