Sumit Sharma

Sumit Sharma has rich experience in Unmanned systems with specialization in Drones architecture development and testing for different applications. He is experienced in Drone Mechanics, Avionics, Design and manufacturing. In his early career, he was involved in the development and testing of the first approved agriculture drone and later getting it approved by the DGCA. Along with this, he has contributed to the development of a Survey drone for Aerial Surveys. He was also involved in the development of high speed and long range surveillance drones for defence tenders. Sumit has been involved in early agriculture spraying pilot projects and was a part of Aerial Spraying on the Locust which hit Rajasthan in 2020.

Developing the control system

In this section, we will cover control system development.

Electronic speed controllers and flight controllers

An electronics speed controller (ESC) is a small device that comes between the flight controller (FC) and the BLDC motors. An ESC, as the name suggests, controls the speed at which the BLDC motor rotates as per the signals received from the flight controller. Each motor requires one ESC to control its speed and is connected to the flight controller. The FC simultaneously has pulse with modulation (PWM) pins to which the ESC is connected. The FC gives the PWM/DShot signal to the ESC as per the commands given by the GCS RC to run the motors. The ESC gets power from the battery and signals from the flight controller. The following diagram illustrates this setup:

The ESC is connected to the battery and supplies the battery voltage to the motors. The ESC is a kind of oscillator...
