System and method for calculating weight distribution of drone

A system comprising:

• a drone and a payload frame connected to the drone
• at least one payload module attached to the payload frame, the payload frame being electrically coupled to the at least one payload module,
• a communication interface coupled between the payload frame and the at least one payload module, the communication interface configured to enable the payload frame and the at least one payload module to communicate with a controller of the drone, and wherein:
• the communication interface is configured to communicate a relative location of the at least one payload module in the payload frame, a weight of the at least one payload module and a volume of the at least one payload module to the controller of the drone, and
• the controller of the drone is configured to calculate a weight distribution within the payload frame based on the relative location of the at least one payload module, the weight of the at least one payload module and the volume of the at least one payload module.
