Provided are a manned mower and an outdoor traveling device. The manned mower includes: a frame; a traveling wheel set mounted to the frame, where the traveling wheel set includes at least rear traveling wheels that include a first traveling wheel and a second traveling wheel; a traveling motor having a drive shaft and configured to drive the traveling wheel set; a mowing element driven by a mowing motor; and a power supply assembly, where the power supply assembly includes at least one battery pack and is configured to power the traveling motor and/or the mowing motor. A ratio of a distance L1 between the first traveling wheel and the second traveling wheel to a radius R of the first traveling wheel is greater than or equal to 6.

A working system of an autonomous mobile device includes the autonomous mobile device, a first base station, and a second base station, where the autonomous mobile device includes a controller and at least one radio, and the controller is configured to, within a current cycle, configure the radio to receive a first signal from the first base station and acquire a first common-view satellite parameter and a first communication parameter with the first base station based on the first signal; after the end of the current cycle, configure the radio to receive a second signal from the second base station and acquire a second common-view satellite parameter and a second communication parameter with the second base station based on the second signal; evaluate a signal quality of the first base station and a signal quality of the second base station based on the first and second common-view satellite parameters and the first and second communication parameters, and in the case where the signal quality of the second base station is better than the signal quality of the first base station, configure, within the next cycle, the radio to receive the second signal from the second base station.

A fastener driver includes: a trigger assembly operated by a user to switch between a first state in which a striker is allowed to strike a fastener and a second state in which the striker is forbidden to strike the fastener; a lifting assembly, where at least part of the lifting assembly is movably disposed in a magazine to drive the fastener to move in the magazine; and a dry fire prevention assembly having a dry fire prevention state, where the dry fire prevention assembly includes a stopper, and in the dry fire prevention state, the trigger assembly is forbidden by the stopper to switch to the first state. When the trigger assembly obstructs the stopper from performing a first motion, the lifting assembly drives the stopper to perform a second motion.
