Unit 2

Second 34 of Unit 2 Overview of Drones

QuestionAnswer
Kv rating a measurement of a motor’s RPM per volt (RPM/volt). The number is a constant that tells you the RPM of the motor when a potential difference of 1V (1 volt) is applied with no load.
LED (light-emitting diode) a two-lead semiconductor light source.
LiPo (lithium polymer) a rechargeable battery of lithium-ion technology in a pouch format. Unlike cylindrical and prismatic cells, LiPos come in a soft package or pouch, which makes them lighter but also less rigid.
mAh milliamp hour and is a unit that measures electric power over time, commonly used to measure the energy capacity of a battery.
magnetometer compass, is an instrument that measures the direction of the magnetic field at a point in space.
microcontroller a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals.
micro SD a Secure Digital (SD) card that has non-volatile memory for use in portable devices.
Mode 1/Mode 2 A configuration used on transmitters. One has the throttle located on the right transmitter stick while the other has the throttle stock on the left.
modem A network hardware device that modulates one or more carrier wave signals to encode digital information for transmission and demodulates signals to decode the transmitted information.
multirotor A rotorcraft with more than two rotors.
nano drones A very small unmanned aerial vehicle.
octocopter An unmanned mulitcopter having eight rotors.
Payload The carrying capacity of an aircraft or launch vehicle, usually measured in terms of weight.
pitch Motion about the lateral axis, and it's a measure of how far an aircraft's nose is tilted up or down.
quadcopter An unmanned multicopter having four rotors.
racing drones Small radio-controlled quadcopters, often equipped with cameras showing the live stream camera feed, designed to compete in races over a set course.
R/C (Radio Control) the use of radio signals to remotely control a drone from a hand-held radio transmitter.
ROV (remote operated vehicle) Refers to remote control vehicles operating on land or in the air.
sensor An electronic device used to measure a physical quantity such as temperature or pressure and convert it into an electronic signal.
servo An electromagnetic device that converts electricity into precise controlled motion by use of negative feedback mechanisms.
stator The stationary portion of an electric generator or motor.
submersible Refers to any device designed to be completely submerged or to operate while submerged.
sUAV Acronym for a Small Unmanned Aerial Vehicle lighter than 55 lbs.
telemetry An automated communications process by which measurements and other data are collected at remote or inaccessible points and transmitted to receiving equipment for monitoring.
terrestrial Means of or relating to land as distinct from water.
torque The tendency of a force to rotate an object about an axis and relates to the lifting power of a drone.
tricopter An unmanned multicopter having three rotors.
UAS (unmanned aerial system) Refers to an unmanned aircraft and all its components.
UAV (unmanned aerial vehicle) Acronym for an Unmanned Aerial Vehicle.
UGV (unmanned ground vehicle) Acronym for an Unmanned Ground Vehicle.
V-tail A configuration that is a 4-motor quadcopter with two of the motors attached on the front arms as normal, but the rear motors are in closer proximity and tilted at a slightly vertical angle.
VLOS (visual line-of-sight) Refers to a normally unobstructed view between an intended observer and a drone. Same as LOS (line-of-sight).
waypoint A reference point in physical space used for purposes of navigation, otherwise known as a landmark.
yaw The aeronautical term used to describe a twisting of a moving aircraft around the vertical axis.
