Picture: A grey quadcopter drone hovers above a quiet map.

Drones, explained.
How they fly, what they see, and what people use them for. Scroll, and we will take one apart.
Picture: The drone comes apart: its four motors and long two-blade propellers are highlighted.
01 · Propulsion
Four motors, no rudder
A quadcopter steers only by changing how fast each motor spins.
Speed up the two motors on one side and the drone tilts away and slides that way. Two props turn clockwise and two anticlockwise, so the body does not spin.
Picture: The battery slides out of the back of the drone.
02 · Power
The battery is the clock
The heaviest single part, and the one that decides how long a flight lasts.
Its own chip reports charge and temperature to the drone, so it can bring itself home before the battery runs low.
Picture: The flight controller board, with its chips, lifts out of the body.
03 · Flight controller
The brain, on one small board
It reads every sensor many times a second and adjusts all four motors to hold the drone steady.
Let go of the sticks and it is this board that keeps the drone hovering in place.
Picture: A small AI computer with cooling fins lifts out, and the camera marks a person and a car on the ground.
04 · Onboard AI
A second brain that sees
A small computer built for AI recognises people, vehicles and obstacles in the camera feed while it flies.
It works on the drone itself, without the internet: that is how a drone can follow a subject or stop before it hits something.
Picture: The satellite antenna on top and the vision sensors underneath are highlighted.
05 · Navigation and sensing
Knowing where it is
Satellites say where on Earth. Cameras underneath and in front say what is close.
Together they let it hold a position in wind, stop before an obstacle, and remember the spot it took off from.
Picture: The LiDAR in the nose sends a fan of laser pulses that leave a point cloud on the ground.
06 · LiDAR
Measuring with light
A LiDAR sends out pulses of laser light many thousands of times a second and times each echo.
Every echo is a point in 3D. Millions of them make a point cloud: the shape of the land, even under trees.
Picture: The camera drops forward on its three-axis gimbal.
07 · Camera and gimbal
A steady eye
The camera hangs on a three-axis gimbal that cancels the drone's tilting.
The body leans into the wind; the picture stays level.
Picture: A small robotic arm unfolds from under the drone and opens its claw.
08 · Robotics
Hands in the air
Some drones carry a small robotic arm or gripper that folds away in flight.
It can pick up a water sample, release a rescue float, or set a parcel down gently.
Picture: The parts come back together into one drone.
Assembled
Put together, it flies
Every part you just saw works at once, many times a second. So what do people do with it?
Picture: Satellites circle on orbits high above the drone, with signal lines down to it.
In orbit
Always under the satellites
Navigation satellites circle the Earth day and night. A drone listens to several at once, from GPS, Galileo, BeiDou and GLONASS, to work out where it is.
Every waypoint on a flight plan is a position those satellites help it find, and the way home is one too.
Picture: Two hands hold the controller; as the thumbs move the sticks, the drone above tilts to match.
You are the pilot
A person is always in control
Two sticks, two thumbs. With AI and satellites on board, it is still a person who decides where it goes, and who can take over at any moment.
The controller talks to the drone over a radio link and shows the camera's view on its own screen.
Picture: The drone circles over a wedding venue with a table, chairs, a flower arch and guests.
In people's lives · Private events
Weddings, debuts and reunions
The view from above that everyone remembers: the venue, the guests, the first dance.
Picture: The drone's camera looks down at a beach.
Recreation
Photos from where you could never stand
Travel, family trips and hobby flying: the most common reason people buy a drone.
Picture: The drone scans the side of a tall tower in town.
Business · Inspection
Checking what is hard to reach
Roofs, towers, bridges and solar farms, looked at closely without scaffolding or climbing.
Picture: The drone patrols in a circle over a large site.
Security · Monitoring
Watching over a large site
Farms, warehouses and events, patrolled along a planned route.
Picture: The drone carries a parcel in its arm over a village.
Support · Delivery
Carrying what is needed
Medicine, samples and small parts flown across water or rough roads where trials allow it, set down by the arm.
Picture: The drone shines a thermal cone into a forest, onto a person.
Rescue
Finding people faster
Thermal cameras pick out body heat at night or under trees, so search teams know where to go.
Picture: The drone flies rows over farm fields that fill in as a map.
3D mapping
A map from above
Flown in rows, hundreds of overlapping photos, or a LiDAR point cloud, become an accurate map or 3D model.
About Waevpoint
Small company, big curiosity
We are based in the Philippines and we love drone technology: how it works, what is new, and what it can do for people here.
Happy to talk about choosing a first drone, how the technology works, learning to fly, or who to ask for a particular job.
