The invention discloses a bionic underwater robot based on electromagnetic drive flexible hinge jet propulsion and a motion control method of the bionic underwater robot, and belongs to the technical field of bionic actuators and robots. The multiple electromagnetic actuators arranged in a matrix mode are sequentially connected to form a hinge structure, every two vertically adjacent electromagnetic actuators are symmetrically arranged, the multiple electromagnetic actuators are all arranged on the rear side of the fairing and connected with the fairing through connecting pieces, and the multiple electromagnetic actuators are independently controlled; the comprehensive phase difference and the reversing time difference of the multiple electromagnetic actuators are controlled through the electromagnetic driving controller, differential propulsion is achieved, and flexible steering and efficient movement are achieved. The overall structure simulates the jellyfish appearance design, the appearance design conforming to the flowing resistance reduction characteristic is adopted, the resistance during movement in water can be effectively reduced, the electromagnetic driver is used for generating power, the annular flexible structure is extruded to enable a fluid medium to be rapidly sprayed out, and efficient underwater propelling of the micro-robot is achieved.

The invention provides multi-degree-of-freedom adaptive center-upper limb combined stroke rehabilitation equipment, and relates to the technical field of medical instruments, the equipment comprises an equipment base, and a back posture self-adaptive module, a center stimulation module and an upper limb training module are arranged on the equipment base; the central stimulation module comprises a multi-degree-of-freedom mechanical arm, a base of the multi-degree-of-freedom mechanical arm is connected with the back posture self-adaptive module, and a transcranial stimulation unit is arranged at the tail end of the multi-degree-of- The upper limb training module comprises at least one multi-degree-of-freedom upper limb rehabilitation mechanism and is spatially associated with the back posture self-adaptive module; and the visual guidance control module is used for collecting pose information of the patient in real time and dynamically controlling the multi-degree-of-freedom mechanical arm and / or the back pose self-adaptive module to perform motion compensation according to the pose information so as to maintain alignment of the transcranial stimulation unit and the target brain area of the patient. The stimulation output of the transcranial stimulation unit and the movement of the multi-degree-of-freedom upper limb rehabilitation mechanism are coordinated; and the precision of collaborative operation and the stability of the rehabilitation effect are improved.

This application provides a belt guide correction component block, a belt guide machine, and a printer, relating to the field of printing technology. The belt guide correction component includes a belt guide roller, a pair of mounting modules, and an adjustment module. Each end of the belt guide roller has a mounting module, which includes a mounting member and an adapter. The adapter and mounting member are hinged, allowing the adapter to swing and rotate. The adapter and belt guide roller are slidably connected, allowing the belt guide roller to slide axially, and the axis of rotation of the belt guide roller and the axis of rotation of the adapter are collinear. At least one mounting module has an adjustment module connected to its mounting member. The adjustment module adjusts the position of the corresponding mounting member in the adjustment direction, thereby causing the mounting member and belt guide roller to swing. This application facilitates correction operations, saves time and labor, and has a simpler overall structure, reducing equipment costs and simplifying maintenance.

The utility model provides a double crank mechanism embroidery machine head relates to sewing embroidery technical field, including the casing, be equipped with the presser foot drive crank in the casing, the presser foot drive crank is connected with needle bar drive crank through same transmission shaft fixedly. Adopt double crank mechanism respectively simultaneously drive needle bar main part and presser foot main part, can make both sides keep a balanced state of opposition in the movement, the movement between two cranks can offset each other axial centrifugal swing, effectively control the vibration produced in axial, reduce the vibration and noise produced when equipment works. Through the coordinated transmission between control connecting rod, make presser foot main part cloth time meet the cooperation between the sewing mechanism, effectively improve the sewing performance. Through a plurality of connecting rod transmission, make presser foot main part and needle bar main part's movement more coordinated, in the both separation and contact instant is in the same speed state, reduce the vibration produced between the impact when mechanism movement, reduce noise and improve the sewing quality.
