A control system configured to control a system including a mobile robot configured to move autonomously and a server configured to be connected to the mobile robot by wireless communication includes one or more processors configured to, when the mobile robot is unable to communicate with the server, determine a state of the mobile robot, including whether the mobile robot has an abnormality, based on information acquired by sensors around the mobile robot.

An aircraft emergency descent method includes setting a pre-set maximum collective blade pitch and a pre-set altitude as part of a failure procedure; monitoring rotor assemblies through an aircraft control system and a failure detection module; determining when a rotor assembly has failed; and activating the failure procedure. The failure procedure includes commanding a maximum torque to a motor of each rotor assembly such that the rotational velocity of functioning rotors increases; detecting the increase in rotational velocity; adjusting either motor torque or a collective blade pitch to regulate rotational velocity; monitoring altitude of the aircraft; and upon determining when the aircraft reaches the pre-set altitude, adjusting the collective blade pitch to the pre-set maximum collective blade pitch via the at least one governor such that momentum is conserved, causing a descent rate of the aircraft to decrease as the aircraft approaches a ground surface.

An aerial vehicle, comprising: one or more motors, one or more sensors, and a flight sub-system. The one or more sensors configured to detect data. The flight sub-system includes an attitude controller module; a rate controller module; and a compensator module. The compensator module is configured to: determine a maximum RPM of the one or more motors or a maximum torque of the one or more motors; receive a torque vector from the rate controller module; determine a rotational speed of the one or more motors to generate a desired flight orientation based upon the torque vector; and consider sensor data from the one or more sensors to adjust the rotational speed of the one or more motors.

A mobile object includes: a remaining energy amount acquisition unit that acquires the amount of energy remaining in the mobile object; and a range specifying unit that specifics, on the basis of the amount of energy remaining in the mobile object, a movement range in which the mobile object can return from the current position to the return position.

Provided is a reception device comprising: a reception part configured to receive the control signal from a transmission device; and a controller configured to performs a process of outputting a motor driving instruction value corresponding to the control signal received by the reception part as a motor driving instruction value for controlling a driving amount of a motor, wherein the controller performs: a hold process for holding and outputting a value corresponding to the control signal during a reception period as the motor driving instruction value when the control signal is not receivable; and a failsafe gradual change process for gradually changing the motor driving instruction value from the value during the hold process toward a failsafe value determined for failsafe when a period of the hold process reaches a certain period.

A vehicle (22) being operable in an autonomous driving mode having a parking brake (17) with a first actuation unit (9) configured to apply or release the parking brake (17); an activation device (10) configured to activate or deactivate the autonomous driving mode; an interlock (11), wherein the interlock (11) is configured to prevent an activation of the autonomous driving mode unless the parking brake (17) is applied by the first actuation unit (9).

An underwater cleaning robot contains a movement device for moving the underwater cleaning robot under water, a cleaning device for cleaning an object located under water, a control device for controlling the movement device and/or the cleaning device and a communication device for receiving and/or transmitting signals from outside the underwater cleaning robot and vice versa. The communication device contains a first ultrasonic transducer for receiving ultrasonic signals transmitted under water and is designed to transmit electrical signals, corresponding to the ultrasonic signals received, to the control device.

An emergency module may determine the occurrence of an autorotation condition for a rotary wing air vehicle controlled by a user. The emergency module may, responsive to determining the occurrence of the autorotation condition, control the air vehicle to enter into an autorotation. The emergency module may perform one or more non-user actions during the autorotation to assist the user with the autorotation. The emergency module may, while performing the one or more non-user actions during the autorotation, allow the user to maneuver the air vehicle by interacting one or more control interfaces of the air vehicle.
