The most popular form of remote control unit for UAVs is shown below. Types of Remote Controls Remote Control Units for Aircraft An 8 or 16 channel transmitter provides additional channels that can be used to control other mechanisms or activate different flight modes provided by the autopilot. Ground vehicles need at least two channels (steering + throttle). how many switches, dials, control sticks can actually be used).Īn aircraft must use a system that supports at least 4 channels (for roll, pitch, yaw, thrust). The number of channels defines how many different physical controls on the remote control can be used to send commands to the vehicle (e.g. The remote control unit and it's included radio module are also referred to as a "transmitter".Īn important quality of an RC system is how many "channels" it supports. The ground- and vehicle- based radio modules are referred to as the transmitter and receiver respectively (even if they support bidirectional communication) and are collectively referred to as a transmitter/receiver pair.
RECEIVER RADIO CONTROL HOW TO
The flight controller determines how to interpret the commands based on the current autopilot flight mode and vehicle state, and drives the vehicle motors and actuators appropriately. The vehicle-based unit is connected to the flight controller. The remote control unit contains a radio module that is bound to, and communicates with, a (compatible) radio module on the vehicle. On telemetry-enabled RC systems, the remote control unit can also receive and display information from the vehicle (e.g. takeoff, land, return to land, mission etc.). speed, direction, throttle, yaw, pitch, roll, etc.) and to enable autopilot flight modes (e.g. The remote has physical controls that can be used to specify vehicle movement (e.g. How do RC Systems Work?Īn RC system has a ground-based remote control unit that is used by the operator to command the vehicle.
You can disable RC checks by setting parameter: COM_RC_IN_MODE to 1. PX4 does not require a remote control system for autonomous flight modes. This topic explains a little about how RC works, how to choose an appropriate radio system for your vehicle, and how to connect it to your flight controller. Archived:FireFly Y6 Tiltrotor (Pixfalcon)Ī radio control (RC) system is required if you want to manually control your vehicle from a handheld transmitter.
