4results about How to "Good grabbing effect" patented technology

The application provides a flexible object grasping method and device, electronic equipment and storage medium, wherein the flexible object grasping method comprises the following steps: adopting a position evaluation strategy model to determine the Q value of each grasping position in a flexible object image; adopting a posture grasping strategy model to determine a grasping target point and a grasping posture according to the Q value of each grasping position; and controlling a mechanical arm to perform a grasping operation on the grasping target point by adopting the grasping posture. The value of each grasping position of the flexible object is obtained by adopting the position evaluation strategy model, so that the mechanical arm can select the best grasping position when grasping the object; and the posture grasping strategy model is adopted to generate appropriate mechanical arm actions, so as to realize stable grasping and operation of the flexible object, thereby effectively improving the grasping effect of the flexible object.

This utility model relates to an anti-loosening expansion bolt for asphalt pavement, comprising a threaded section, a raised section, a barb assembly, and a nut. During the actual installation of asphalt pavement guardrails, holes can be drilled in the asphalt pavement. The barb is then rotated and retracted into a receiving groove. The threaded section and raised section are then placed into the drilled hole. The nut is then rotated using a tool, causing it to engage with the ground and slowly pull the threaded section and raised section upwards. Simultaneously, the barb slowly pierces into the surrounding soil as it rises. Once the barb is fully extended, the resistance to nut rotation increases, stopping the rotation of the nut. The guardrail is then installed on top of the threaded section, thus achieving better fixation to the asphalt pavement and maintaining good grip even during hot weather, preventing the installation equipment from falling off.

The utility model relates to a thin-wall pipe fitting grabbing manipulator which comprises a supporting arm, and a connecting base is installed at the top of the supporting arm. The supporting arm comprises a top plate located at the top and two vertical plates extending downwards from the top plate, and a middle area is formed between the two vertical plates. A pair of cylinders of which the bottoms are hinged is mounted in the middle area; the middles of the pair of clamping arms are rotationally connected to the supporting ends on the two sides of the lower portion of the vertical plate correspondingly. Push rods of the pair of air cylinders are correspondingly connected to the top ends of the clamping arms respectively. Rubber chucks are respectively mounted at the lower ends of the clamping arms; the auxiliary supporting plates are connected to the outer vertical face, away from the center, of the vertical plate through connecting screws; the vertical plate is provided with a first avoiding area; according to the scheme, positioning and clamping of the thin-wall part can be achieved without too large clamping force, and the grabbing effect is greatly improved; and the device has the advantages of simplicity in manufacturing, convenience in use, no scratch on part surfaces, large adaptive pipe fitting diameter range and the like.

The application discloses a tendon-driven flexible gripper based on Miura plate folding design, which comprises a driving input module, a fixed bearing platform, a sliding platform and a Miura plate base. The driving input module is composed of a rotating disc and a transmission rope system. The rotating disc is used to drive the transmission rope system to move, and the transmission rope system is designed in a closed path. The clockwise and counterclockwise rotation of the rotating disc will respectively cause the transmission rope system to retreat and advance. The transmission rope system is connected with the sliding platform, and the two ends of the Miura plate base are respectively connected with the fixed bearing platform and the sliding platform. When the rotating disc rotates, the Miura plate base is folded or unfolded along the preset crease line, so that the state of the Miura plate base changes between clamping and flat unfolding. The soft gripper of the application is driven and controlled by a single steering engine to realize the opening and closing movement of the gripper, and the equipment quality and the driving control complexity are significantly reduced.
