This invention belongs to the field of mobile robot technology, specifically relating to a "walking-moving" composite six-legged robot based on a heterogeneous dual parallel mechanism. The robot includes an inner upper platform, three outer upper platforms and a lower platform, three parallel mechanical legs, three series branches, and three telescopic legs. The inner upper platform is hinged to the three outer upper platforms, forming a foldable equilateral triangle structure. The three series branches of the UPU configuration are respectively connected to the inner upper platform and the lower platform, forming a 3-UPU parallel mechanism. The three 2RUS&UP configuration mechanical legs are fixed to the outer upper platforms via fixed plates, and the axes of the three UP branches pass through the respective apex corners of the outer upper platforms. Stepping and posture adjustment are achieved by alternately controlling the pose of the 2RUS&UP parallel mechanical legs and changing the telescopic length of the UPU series branches. The alternating stepping of the parallel mechanical legs and the series branches enables the robot to adapt to various complex terrains such as irregular steps, narrow passages, and sharp turns, which is of great significance for exploring complex underground spaces with diverse terrains.

This invention relates to the field of biotechnology, specifically to a method for constructing high-throughput sequencing libraries, a kit, and a method for detecting aminoacylated tsRNA. The method for constructing high-throughput sequencing libraries includes the following steps: (1) first-level enzymatic treatment; (2) second-level chemical treatment; (3) third-level enzymatic repair; (4) library construction. This invention constructs a triple cascade treatment system of "specific enzyme digestion labeling - denaturation deaminoacylation - enzymatic modification and repair", which overcomes the three major technical bottlenecks that have long existed in the sequencing of transport tRNA-derived fragments: "signal missed detection", "full-length truncation" and "confusion of active state".

This invention relates to a low-temperature difference indirect temperature control multifunctional bathing aid device, comprising a bathtub and a bathing chair. On one hand, this invention indirectly adjusts the temperature of the bath liquid in the bathtub based on the temperature control of the water tank, and ensures that the water discharged from the bathtub can circulate and return while maintaining equal supply and return volumes. This not only eliminates safety risks caused by temperature differences in the bath liquid, but also avoids direct temperature control. Constant temperature control is achieved while the bath liquid is flowing, preventing direct waste discharge. Furthermore, based on the massage or acupoint stimulation function created by the water jets, and the equal supply and discharge of water in the water replenishment chamber, interference between inflow and outflow is avoided. The water replenishment chamber serves as the optimal water temperature monitoring area for more accurate temperature control. On the other hand, the built-in locking mechanism eliminates interference or obstacles caused by external components, preserving the overall aesthetic appearance of the bathtub. The locking force, generated by the internal squeezing force from multiple points on the lock head, not only allows for adjustment but also reduces safety risks associated with bathing.

The application provides a battery replacing system and a battery replacing method. The battery replacing system comprises a battery pack, a battery compartment and a battery replacing platform, and further comprises a locking mechanism and an unlocking mechanism. The locking mechanism comprises a locking rod, a locking seat, a locking tongue and a connecting rod. One of the locking rod and the locking seat is connected to the battery pack, and the other is connected to the battery compartment. The locking seat is provided with a locking hole, and the locking hole has a locking opening. One end of the locking tongue is rotatably connected to the locking seat, and the other end is rotatably connected to the connecting rod. The unlocking mechanism comprises an unlocking rod and an unlocking driving assembly. The unlocking rod is rotatably connected to the battery replacing platform. During the process in which the unlocking driving assembly drags the unlocking rod to swing to an unlocking position, the unlocking rod pushes the connecting rod, and the connecting rod drags the locking tongue to separate from the locking opening to remove the obstruction to the locking rod, thereby realizing the unlocking operation of the locking mechanism.

This utility model discloses a filter bucket with a pull-out water-drawing mechanism, including a bucket body and a bucket lid. The bucket lid has an inlet and an outlet. A filter assembly is installed inside the bucket body. A water pump assembly is installed between the outlet and the filter assembly. A pull-out water-drawing assembly is installed between the inlet and the filter assembly for manually drawing water into the bucket body before the water pump assembly is started. The pull-out water-drawing assembly includes a cylinder. The upper end of the cylinder is connected to the inlet, and the lower end of the cylinder is connected to the filter assembly. A piston is installed inside the cylinder, and a one-way valve structure is installed at the piston. A push-pull rod extending out of the bucket lid is connected to the piston. This utility model has the advantage of being able to conveniently complete the water-drawing operation without disassembly.
