5 Radio Systems for Robotics and Drone Applications



This guide will help you in choosing a reliable and budget radio for your hobby. 

The article is based on different radio systems which are available in the market. The radio systems are an integral part of any wireless system. The radio system consists of a transmitter and receiver which helps in data communication between the sender and the receiver.

Robotics and Drone application generally works on 2.4GHz and 5.8 GHz which are Industrial, scientific, and medical radio band (ISM band). This provides less interference and better capacities to the communication systems.

Some of the Key Parameters when selecting a Radio System :

  • No. Of Channels Available for transmission.
  • Operating Voltage of the transmitter and receiver.
  • Size of Reciever according to the application.
  • Failsafe Methods and other features.
  • Channel Mixing and calibrating methods.
  • Received signal out mode – PPM, PWM or Sbus.

The article will discuss 5 different companies who are in the field of Radio designs and offers a variety of products.
