Crime and robbery is a major deterrent to
economic growth across the Caribbean. An
innovative flying robot capable of deterring
thieves from entering a property or stealing
items after entering will boost our economy.
This robot will reduce crime related to
robbery and encourage economic development.
A mobile camera system will reduce the cost of
having a camera in each room. This robot will
fly around to locations in the house where
motion is detected and record images.

The very awareness of this innovation will
deter potential thieves.

Creativity and Innovation

The quadcopter security robot will be made
from plastic and powered by a 9 volt battery
and a mini solar panel.

Plastic is a light material and hence would
require less battery power during flight.
Using mini solar panels on the flying robot
will allow the harnessing of energy from
ambient lighting entering the building.

The robot will also be able to self charge by
landing at a charging location to recharge the
batteries.

Content and Knowledge of Project 15

To reduce the embodied energy in the
manufacturing of the robot, recycled plastic
will be utilized for making the robot. This
will reduce the environmental impact.
