Method and system for landing an unmanned aerial vehicle
First Claim
1. A method of landing an unmanned aerial vehicle on a vehicle, wherein the unmanned aerial vehicle has a crash cage, wherein the vehicle has a base station configured to receive the crash cage of the unmanned aerial vehicle, and wherein the crash cage is a resilient structure, the method comprising:
- determining a velocity of the unmanned aerial vehicle;
determining a velocity of the vehicle;
adjusting the velocity of at least one of the unmanned aerial vehicle and the vehicle to ensure that a difference between the velocity of the unmanned aerial vehicle and the velocity of the vehicle is greater than a predetermined amount as the unmanned aerial vehicle physically engages the vehicle;
adjusting the velocity of at least one of the unmanned aerial vehicle and the vehicle to ensure that the difference between the velocity of the unmanned aerial vehicle and the velocity of the vehicle is above a predetermined value as the crash cage engages the base station;
determining a spring rate of the crash cage;
determining a force at which the crash cage engages the base station;
determining a maximum deformation of the crash cage as the crash cage engages the base station; and
deploying a deployable restraint before the crash cage reaches its maximum deformation.
