The present invention discloses an artificial muscle collaborative mirror rehabilitation system and control method based on ultrasonic detection control. The rehabilitation system includes an ultrasonic detection group, a pneumatic muscle group, and an electric control group. The ultrasonic detection group performs high-density array ultrasonic detection on the muscles of the user's healthy limb to obtain the muscle state of the healthy limb, and analyzes the muscle state information through the electric control group to resolve the limb collaborative movement information. The pneumatic muscle group simulates the layout and attachment method of human limb skeletal muscles on the bones, and is controlled by the electric control group for collaborative drive to achieve mirror movement of the healthy limb. The present invention adopts ultrasonic detection and pneumatic muscle simulation of mirror movement, which can detect the movement pattern of the healthy limb (including movement amplitude, movement angle, movement speed and strength, etc.) at the muscle level, and collaboratively control the affected limb in real time to completely imitate the movement of the healthy limb, so that the rehabilitation equipment can assist the patient to achieve the mirror movement effect and improve the rehabilitation efficiency.

The invention relates to the technical field of shooting equipment, in particular to an autonomous mobile platform automatic mirror conveying system and method based on a global UWB coordinate system. The method comprises the following steps: deploying a fixed UWB base station and a label to construct a UWB measurement coordinate system; establishing a transformation relation with an actual physical space through system calibration, and obtaining a global coordinate system for positioning and control; in the recording mode, the mobile shooting unit is controlled to carry out mirror movement on a target, the pose time sequence of the mobile shooting unit and the target mirror movement in a global coordinate system is synchronously collected and recorded, and a digital mirror movement track template is generated; and in the reproduction mode, based on the template, the global coordinate system and the target pose obtained in real time, a control unit of the autonomous mobile shooting platform generates a motion control instruction and executes the motion control instruction so as to accurately reproduce the mirror moving track. The system comprises a global reference end used for establishing a coordinate system, a moving target end worn on a shooting target, and an autonomous moving shooting platform comprising a platform body, a UWB tag, a control unit and a shooting holder.

The application discloses an ultrasonic knife head amplitude intelligent testing device and method, which comprises a base plate for fixing the ultrasonic knife head, a sensing head for emitting and receiving testing laser, a mirror for reflecting the testing laser, a mirror adjusting mechanism for controlling the mirror movement, a sensing head adjusting mechanism for controlling the sensing head up and down movement, a main machine for controlling the sensing head adjusting mechanism and a controller, and a display for data display. The detection method comprises the following steps: S1, installing the ultrasonic knife head in place and starting the main machine; S2, presetting the relative position of the ultrasonic knife head, the sensing head and the mirror; and S3, performing laser on the specified region of the ultrasonic knife head, thereby confirming the position of the maximum amplitude and marking. The application has the beneficial effect that the ultrasonic knife head is fixed, the ultrasonic is continuously excited for a period of time after the system is powered on, the positioning and amplitude confirmation marking are automatically completed by the main machine, and the error caused by secondary processing is avoided.

The present invention discloses an active-passive lower limb mirror rehabilitation exercise training robot, which belongs to the field of rehabilitation medical equipment. The robot is mainly composed of four parts: a base, a base assembly mechanism, an active motion mechanism, and a passive motion mechanism. The base is used to fix and support the entire mechanism; the base assembly structure is fixedly installed on the base and is used to install the passive motion mechanism and the active motion mechanism; the passive motion mechanism drives the active motion mechanism to move in a circular trajectory in the vertical plane through a motor-driven passive rotating drum, thereby realizing the patient's passive mirror rehabilitation training of the hip, knee, and ankle in the vertical plane; the active motion mechanism drives the passive mirror movement of the affected limb through the active movement of the healthy limb, thereby realizing the patient's active mirror rehabilitation training of the hip, knee, and ankle in the vertical and horizontal planes, as well as the active mirror rehabilitation training of the plantar flexion / dorsiflexion of the ankle. The present invention can realize multiple active and passive training modes, and has a light structure, flexible movement, safety and stability, and strong practicality.
