Methods and systems for deploying a payload from an aerial vehicle onto a target surface

A system for deploying a payload from an aerial vehicle onto a body of an animal, the system comprising:

• a delivery device detachably couplable to the aerial vehicle, the delivery device comprising:
• an elongated shaft comprising a proximal end and a distal end;
• a plurality of fins extending along the elongated shaft;
• and
• a payload holder coupled to the distal end of the elongated shaft, wherein the payload holder is detachably couplable to the payload, wherein the payload holder is configured to detach from the payload in response to the delivery device impacting the body of the animal.

A method for deploying a payload from an aerial vehicle onto a target surface, the method comprising:

• detachably coupling a delivery device to the aerial vehicle via a dropper device, wherein the delivery device comprises:
• an elongated shaft comprising a proximal end and a distal end, a plurality of fins extending along the elongated shaft, and a payload holder coupled to the distal end of the elongated shaft, wherein the payload holder is detachably couplable to the payload;
• positioning the aerial vehicle substantially above the target surface;
• receiving a signal at a wireless receiver to detach the delivery device from the aerial vehicle;
• transmitting the signal from the wireless receiver to the dropper device;
• detaching the delivery device from the aerial vehicle via the dropper device;
• impacting the delivery device onto the target surface;
• and
• detaching the delivery device from the payload.
