In order to enable autonomous flight,

there are a few key components
that we need in every robot.

We're gonna discuss very briefly,
what these key components are.

The first is state estimation.

This refers to the ability of
the vehicle to estimate its position,

its orientation, and the velocity.

In other words, the rate of change
of position and orientation.

Second, the vehicle must be able
to compute its control commands.

Based on where it needs to go and based on
what its estimate of its current state is,

the vehicle must be able to compute
the commands that need to be sent

to the motors or the rotors, and

have them rotate at the appropriate
speeds to achieve the desired action.

Third, the vehicle must have some basic
capability to map its environment.

If it does not know what
the surrounding environment looks like,

then it's incapable of reasoning
about this environment and

planning safe trajectories
in this environment.

And then finally of course,
given a set of obstacles and

given a destination, the vehicle must
be able to compute a trajectory,

a safe path to go from
one point to another.
