Quadcopters are a simple form of UAV’s with four rotors. They can be either autonomous or controlled remotely by a human on the ground. They have leading aspects in various fields like military, surveillance, medical, and many.&nbsp; The extensive growth in the usage of quadcopters is propelling the researchers towards an efficient design. The frame weight is one of the important parameters that will affect the flight-time and battery power consumption. The present work mainly focuses on the reduction of quadcopter frame weight. The technique of generative design method is employed on the quadcopter frame to reduce the overall mass. Autodesk Fusion 360 software is used for the design and numerical analysis of the frame structure. For validating the present numerical analysis technique used in the present work, the equivalent stress and deformation values obtained in the present work are compared with past research carried by Singh et al. (2019), under similar loading conditions. After validation, maximum stress and deformation values on the arm structures are studied by providing a thrust load of 15.47 N at four motor-mounting locations. The maximum stress and deformation values obtained in the present work are 3.03 MPa and 0.2737 mm against the 6.2705 MPa and 5.8439 mm values of Singh et al. (2019). The maximum stress value obtained is less than the yield stress value of the thermoplastic material polyamide nylon 6 when maximum thrust loads are applied on the frame. The numerical analysis concluded that the frame designed in the present study resulted in an improved frame that can withstand maximum thrust load and produce minimum deformation.

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
