The present disclosure discloses an unmanned aerial vehicle (UAV), comprising a housing having a top part and a bottom part, a plurality of arms arranged on the top part, each arm having a motor and an airscrew, a battery unit arranged within the housing, a processor arranged within the housing, a sonar unit having a wire connected thereto, and a positioning unit detachably mounted within a mounting groove recessed from the bottom part, wherein the positioning unit is connected to the wire and configured to retract or release the wire. An UAV readily configured for fishing can be provided by embodiments of the present disclosure.

Provided are a method of controlling a mobile robot, apparatus for supporting the method, and delivery system using the mobile robot. The method, which is performed by a control apparatus, comprises acquiring a first control value for the mobile robot, which is input through a remote control apparatus, acquiring a second control value for the mobile robot, which is generated by an autonomous driving module, determining a weight for each control value based on a delay between the mobile robot and the remote control apparatus and generating a target control value of the mobile robot in combination of the first control value and the second control value based on the determined weights, wherein a first weight for the first control value and a second weight for the second control value are inversely proportional to each other.

A quadcopter pressure washer that may facilitate cleaning objects and surfaces in remote areas. The quadcopter pressure washer includes a tubular airframe, a plurality of rotary motors, a battery and controller, a pair of antennae, a signal receiver, a nozzle, a turret, a high-pressure hose, a pressure washer, a direct current or a DC power source, an alternating current/direct current or a AC/DC converter and a 120V AC power source. The quadcopter pressure washer also includes an operator control panel include additional a pair of antennae that extend upward in a programmable position from the operator control panel to transmit or receive any suitable electromagnetic signals. The additional pair of antennae utilizes state-of-the-art Doppler radar technology in electrical communication with the battery and controller. The operator control panel includes a signal emitter positioned in front of the operator control panel.

In some embodiments, systems, apparatuses and methods are provided to enhance delivery of packages. Some embodiments provide an unmanned delivery system comprising: a rotational drive shaft; a crane motor cooperated with the drive shaft that is rotated by the crane motor; a first crane system with a first cord fixed with the first crane system, wherein the first crane system is configured to cooperate with the drive shaft to control the first crane system in controlling the spooling and retraction of the first cord; a control circuit coupled with the crane motor; and a stop switch electrically coupled with the control circuit and positioned to be contacted by a package release hanger secured with the first cord when the first cord is retracted to a first threshold; wherein the control circuit is configured to stop the crane motor in response to receiving a signal from the stop switch.

A system is provided that includes an assembly adapted to support a first body relative to a second body. An elastomeric body is configured with a mounting aperture for receiving the first body. The elastomeric body includes a first protrusion and a second protrusion. A frame wraps about a perimeter of the elastomeric body. The frame is configured with a first window and a second window. The first protrusion extends through the first window to a distal end of the first protrusion. The second protrusion extends through the second window to a distal end of the second protrusion. Spring elements are adapted to mount to the second body. The elastomeric body is disposed between the first and the second spring elements such that the first spring element engages the distal end of the first protrusion and the second spring element engages the distal end of the second protrusion.

A workpiece manipulation system to provide high-precision manipulation of a workpiece by an aircraft. The workpiece manipulation system comprises a lifting mechanism to couple with the aircraft, an end-effector, and a processor. The lifting mechanism includes one or more joint actuators to extend or retract the lifting mechanism relative to the aircraft. The end-effector includes an end-effector actuator to control an operation of the end-effector to manipulate the workpiece. The processor is communicatively coupled with the aircraft processor and configured to control operation of the end-effector actuator and the one or more joint actuators. In operation, the processor provides feedback to the aircraft.

A terminal lead assembly for use in an integrated drive generator has a body formed of a lead portion and a support portion. The lead portion is received within an aperture in the support portion. The support portion has an outer periphery defined within a plane extending perpendicularly to a central axis of the lead portion. The outer periphery includes two curved portions and straight side portions extending parallel to each other and connecting the curved portions. An integrated drive generator and a method are also disclosed.

An example operation may include one or more of receiving a request to authorize an in-flight transfer of a parcel between a source unmanned aerial vehicle (UAV) and a target UAV, authenticating, via a blockchain, an identity of the source UAV and an identity of the target UAV based on one or more predefined keys included in the request, and in response to the blockchain authentication being successful, initiating delivery of the parcel from the source UAV to the target UAV while one or more of the source UAV and the target UAV are in-flight.
