An Energy-Efficient and Safe Landing Multirotor Design for Drones

Unmanned Aerial Vehicles (UAVs) or drones are flying robots, which can be controlled either remotely or autonomously to accomplish a certain mission. Drones have now become incredibly well-known and are being used in different applications such as defense, telecommunication, agricultural, and disaster management. However, they continue to face several challenges in their design; one challenge of drones is the energy consumption of their batteries during mission execution. Drones need relatively high energy for cancellation of gravity force; as a result, their flight duration is highly constrained. Another challenge that might happen is the failure of any of the drone's motors. In this case, either hardware or software system should be used to attain safe landing. Therefore, there is a need for a design that can reduce the power consumption in drones and assist in safe landing in case of failure of any drone's subsystem. This study addresses these issues and proposes an energy-efficient and safe landing design for drones. The proposed design suggests that a drone is constructed from a soft silicon material with Helium injection and uses a Penta-copter that has a fixed motor at the center and four motors around the tube. The advantage of this design is the reduction of drone's weight which helps to reduce power consumption, increase flight time, and provide safe landing. However, delicate materials can be pierced and environmental factors like wind can quickly alter the motion.
