A control system for a lift device includes a base controller. The base controller is configured to operate, in coordination, a base assembly of the lift device and a lift assembly of the lift device in order to move an implement. The base controller is configured to receive, from an implement controller, an interface target path for an interface between the implement and the lift assembly. The base controller is also configured to, in response to determining that the lift assembly is capable of moving the interface along the interface target path, operate the lift assembly to move the interface along the interface target path.

A system for a worksite includes a lift device coupled to one or more sensors and an implement assembly, and a visual indicator provided at a location at the worksite. One or more sensors of the lift device detect the visual indicator. The visual indicator represents one or more commands for the lift device to perform one. The visual indicator can be a symbol, a code, or an object, and the lift device is configured to determine the content of the command the whether the command applies to the lift device based on one or more aspects of the visual indicator such as its size, shape, or color.

An autonomous mobile robot includes a chassis, tractive elements coupled with the chassis, a primary mover, and an implement assembly. The primary mover is configured to drive the tractive elements to transport the autonomous mobile robot. The implement assembly is coupled with the chassis. The implement assembly includes a deck configured to define a work area configured to support a material, equipment, and tools for transport to a worksite. The implement assembly also includes a lift interface operably coupled with an implement actuator. The lift interface is configured to be driven by the implement actuator to removably couple with the material, equipment, or tool, and lift the material onto the deck for transport to the worksite.

A lift device includes a chassis, an implement assembly, a lift assembly, a support platform, a user interface, and a controller The implement assembly includes an implement. The lift assembly is coupled to the chassis and the implement assembly. The lift assembly includes an actuator to move the implement assembly relative to the chassis. The support platform is coupled to the lift assembly. The controller can, in a first mode of operation, autonomously control at least one of the implement or the actuator. The controller can also, in a second mode of operation, control at least one of the implement or actuator based on user input data including a command from an operator. The controller can transition from the first mode of operation to the second mode of operation in response to (a) a request from the operator via the user interface or (b) data from a sensor.

Load management system and methods are described for aircraft, including tailsitters. A load management system can comprise a pole coupled the fuselage and free to rotate and swing. The pole can comprise a cargo hook and a distal end that can be releasably coupled to a cargo cable or cargo. The pole can be coupled near its distal end to a retractable cable that is deployed from a position aft of the pole. During landing, takeoff, and when otherwise in hover mode, the retractable cable can be retractedholding the pole along or near the fuselage. During transition to, or during, flight mode, the retractable cable can be deployed which can harmonize the cargo's center of gravity with the needs of the tailsitter aircraft.

A control system for controlling a second unmanned aerial vehicle that flies while holding a first cable connected to a first unmanned aerial vehicle that performs work and a second cable extending from a cable reeling machine, includes a sensor to sense a surrounding environment and output sensor data, and a controller configured or programmed to control operation of the unmanned aerial vehicle and, during flight of the second unmanned aerial vehicle, detect the first cable and the second cable based on the sensor data, and upon predicting that at least one of the first cable and the second cable will contact the ground or an obstacle on the ground, change a trajectory of the second unmanned aerial vehicle to avoid the contact.
