Multirotors

The familiar drone — one or more rotors lift it straight up, let it hover and move in any direction, and make it the default for cameras, inspection and spraying.

What it is

A multirotor gets all of its lift from several fixed-pitch rotors and steers by changing their relative speeds. Nothing moves but the rotors, which makes it simple, cheap and able to hover and take off from a tabletop. The cost is efficiency: every second aloft is spent holding its own weight up with thrust, so flight times are tens of minutes, and a flight controller must correct it constantly to stay level.

Quadcopter, hexacopter and octocopter name the rotor count; multicopter is the generic term. In this taxonomy the rule is lift from rotors alone and no fixed wing; a single-rotor helicopter counts. Add a wing for cruise and it becomes a hybrid VTOL.

What they are used for

  • Photography and video — folding camera drones from the pocket-sized DJI Mini 4 Pro to the Mavic 4 Pro.
  • Inspection and public safety — enterprise models like the DJI Matrice 4 and Skydio X10, with thermal cameras and obstacle avoidance for roofs, power lines and search work.
  • Agriculture — spray and spreader drones like the DJI Agras T50 that treat a field a swath at a time.
  • Research and racing — small quads on open flight controllers for swarm and control work, or flown through goggles.

What to compare

Attribute Why it matters In this catalogue
flight_time The limit on every job; swapping batteries is the workaround 34 min (DJI Mini 4 Pro) – 51 min (DJI Mavic 4 Pro)
max_takeoff_weight Below the registration threshold or above it changes who may fly it where 1.43 kg (DJI Matrice 4 Series) – 103 kg (DJI Agras T50)
payload A camera gimbal, a thermal sensor, or tens of kilos of spray 0.2 kg (DJI Matrice 4 Series) – 50 kg (DJI Agras T50)
ip_rating Most consumer drones have none; enterprise and agricultural ones are rated for rain 2 entries
autonomy From hold-position only to full obstacle avoidance and mission flight semi-autonomous (2), assisted (2), autonomous (1)
sdk Enterprise lines offer mobile and onboard SDKs; consumer ones rarely do proprietary (5)
open_source Open flight controllers are what research and racing builds run on not yet in the catalogue

Edge cases

  • Coaxial rotors (two stacked per arm, as on the Agras T50): still a multirotor.
  • Tiltrotors and tail-sitters with a wing: hybrid VTOL.
  • Single-rotor helicopter drones: multirotor — the rule is rotor lift with no wing, whatever the rotor count.
  • Toy quads with no programmable interface fail the Robot inclusion rule and are not listed.
