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.
