Discuss policy in manufacturing (incentive,
tax, land admin, public safety, legislation)

Policy and legislation will be an important
component of accelerating sales of the robot.
Incentives such as tariff removal for solar
panels and batteries will reduce inputs and
increase cost efficiency.

Tax breaks during manufacturing will also
incentivize the realization of the robot.

Public safety policy will also benefit the
industry by providing parameters under which
quadcopters can fly in the presence of humans
and not harm them.

There are a number of principles of product
design that the product will employ such as:

Flexibility in use
Simple and intuitive – No extensive experience
will be needed to operate the robot. It will
be designed to simply be placed in the home
and start working autonomously, sending video
images to a desired smartphone or website.

Tolerance for error – The robot will be
designed to operate under harsh conditions and
around children.

Low physical effort – The robot will require
very little physical effort or concentration
to commission by the customer.

Size and space for approach – The robot will
be small so it would be able to navigate small
areas.

How bio-mimicry aid the product design – The
robot will use bio-sonar technology adopted
from animals such as bats that use
echolocating.

This will be done by using a sensor that emits
a sound at a specific frequency and listens
for feedback. This will help to locate walls,
fixtures and other elements in and around the
home.
