Development of Centimeter‐sized Aerial Vehicles

From the viewpoints of stability and safety in outdoor flights, a centimeter-sized UAV probably has a larger possibility to be used in our everyday lives than different sized UAVs. Centimeter-sized fixed-wing UAVs that have already been developed can make autonomous flights. However, their flight speed, that is, their momentum, is fairly high. To use them, their flight speed must be decreased. On the other hand, centimeter-sized rotary-wing UAVs that have also already been developed can also make autonomous flights. However, their weight is fairly large. To use them in our daily life, their weight must be decreased. Longer flight duration is also required. For both fixed-wing and rotary-wing UAVs, higher reliability is also required.
