    Abstract: An elevation device includes a mounting frame, a rotary actuator fixed to the mounting frame, a shaft connected to the rotary actuator and rotatable with respect to the mounting frame, a drive bar slidably connected to the mounting frame, and a connecting member fixed to the shaft. The shaft defines a helical groove in a lateral surface thereof. The drive bar includes a post that is movably fit in the helical groove. The mounting frame, the shaft and the drive bar constitute a conversion mechanism that converts rotation of the shaft into linear motion of the drive bar. The drive bar is slidable with respect to the mounting frame along a direction that is parallel to an axis of rotation of the shaft.

    Abstract: A waist rotation structure includes a mounting disc defining a through hole, a rotatable disc located at a first side of the mounting disc, a driving device fixed to a second side of the mounting disc that is opposite the first side, and a transmission assembly. The rotatable disc defines a first cable insertion hole. The driving device includes an output shaft. The transmission assembly includes a drive gear connected to the output shaft, and a transmission cylinder extending through the through hole. The transmission cylinder includes a body that extends through the through hole, and is rotatably connected to the mounting disc and fixedly connected to the rotatable disc, and a driven gear arranged on a lateral surface of the body and engaged with the drive gear. The body defines a wiring hole extending opposite ends thereof and aligning with the first cable insertion hole.

    Abstract: The present disclosure relates to a recharging robot system. The recharging robot system may include a signal emission device including at least one signal emission channel. The at least one signal emission channel each comprises an opening. A distance between two central axes of any two adjacent signal emission channels is gradually increased along a direction facing away the signal emitters. As such, an overlapping area of signal ranges of the at least two signal emitters may be reduced, and the robot may accurately determine which signal range that the robot is within, so as to accurately align with the recharging dock.
