The invention relates to the field of robots, and provides a bionic eye device. The bionic eye device comprises two bionic eyeball bodies; the two ends of the first connecting rod are in transmission connection with the two bionic eyeball bodies through transmission assemblies respectively; the first driving part is hinged to the first connecting rod so as to drive the first connecting rod to rotate in the horizontal plane, and the first connecting rod drives the two bionic eyeballs to rotate in the horizontal plane based on the action of the first driving part; the second driving part is connected with the first driving part so as to drive the first driving part and the two bionic eyeballs to rotate in a vertical plane. According to the bionic eye device, the movement of a bionic eyeball is closer to the physiological mechanism of a real eyeball; the precise control on the movement of the bionic eyeball is realized; the bionic eyeball device is compact in structure, high in integration level and convenient to install and maintain.

The invention belongs to the technical field of manipulators, and particularly relates to a visual positioning device for manipulators, which comprises a main mechanical arm, the top end of the main mechanical arm is rotatably connected with a monitoring mechanical arm, the front end of the monitoring mechanical arm is rotatably connected with a mechanical arm force arm, and a mechanical claw can be additionally arranged at the front end of the mechanical arm force arm. The monitoring mechanical arm comprises a hollow adapter plate, front end sleeves are symmetrically arranged on the front portion of the outer surface of the hollow adapter plate, a monitoring assembly is arranged at the axis position of the lower surface of the hollow adapter plate, and inner sealing parts are arranged in inner cavities of the front end sleeves. When the protective barrel shell is replaced, the protective barrel shell needs to be taken down from the outside of the scanning camera, at the moment, the scanning camera loses the protection effect and is exposed in the external environment, a layer of front end sleeve is further arranged outside, when the protective barrel shell is replaced, the penetrating window can be sealed, and a layer of protective shell surrounds the outside of the scanning camera; and the problem that the outer surface of the scanning camera is easy to pollute at the moment is prevented.

The full-automatic visual training box comprises a box body, a mobile phone clamping seat, a mobile phone, a storage battery, a control module, a charging socket, a training lens, a motor speed reducing mechanism and a crawler track, the front side of the box body is provided with a sighting mark observation hole and a lens slot, and the training lens is inserted into the lens slot; the storage battery and the control module are installed in the element box, an opening is formed in the upper portion of the rear end of the box body, the cover plate and the motor reducing mechanism are installed at the rear end of the opening, a driving belt wheel is installed on a power output shaft, and a driven belt wheel is installed at the front end of the opening. The mobile phone clamping seat is mounted on the conveying belt, and a mobile phone is mounted in the mobile phone clamping seat; the power output end of the control module is electrically connected with the power input end of the motor reducing mechanism. The device is compact in structure and convenient to carry, lenses with different degrees can be conveniently replaced, the distance between sighting marks can be conveniently adjusted, trainees can train at any place, and beneficial technical support is provided for improving vision.

The present application provides use of NeuroD1 in preparation of a drug for converting retinal Muller glial cells into neurons. The present application also provides a method for converting mouse retinal Muller glial cells into neurons, which comprises overexpressing neurotranscription factor NeuroD1 in mouse retinal Muller glial cells. After overexpression of NeuroD1 in mouse retinas by using an adeno-associated virus vector, the present application induces conversion of retinal Muller glial cells into retinal neurons, which can be applied to repair retinas damaged or degenerated due to diseases, thereby restoring vision.

The invention relates to an eye visual training device, which is characterized in that gas blown by a cylinder becomes larger when a watched object block reaches the front of the eyes, and gas in the watched object block is pumped out and becomes smaller when the watched object block returns to the original point, so that the eyes are induced to watch the watched object block, and the eyes are trained to watch large and small according to the change from large to small and from near to far; the device is not in contact with the eyes outside the eyes, strong light does not stimulate the eyes, secondary damage to the eyes is avoided, and the recovery effect is good, so that the device has a very huge application prospect in the eye vision recovery process.
