Abstract: An unmanned aerial vehicle that delivers a package includes a plurality of rotary wings, a plurality of first motors, a main body, a connector, a movable block, and a processor. When the connector is connected to a rail, the processor sets a rotation rate of the plurality of first motors to a rotation rate that is lower than a minimum rotation rate necessary for floating and higher than a minimum rotation rate necessary for propulsion along the rail. Furthermore, the processor causes the movable block to increase the angle formed by the normal direction of an imaginary plane containing the plurality of rotary wings relative to a support direction of the connector.

Abstract: An information processing apparatus includes a transmission unit, a reception unit and a processor. The transmission unit transmits a packet. The reception unit receives a packet. The processor measures a load ratio, which is a usage rate of a band between the transmission unit and the reception unit, when the transmission unit is transmitting the packet to the reception unit. Then, the processor sequentially adjusts a plurality of parameters whose changes insetting lead to changes in the load ratio, in descending order of influence on an increase/decrease in the load ratio in such a manner that the measured load ratio becomes closer to a determined load ratio.
