  • Publication number: 20220172104
    Abstract: A reinforcement learning system is provided, including at least one agent and a server. According to a set condition, the at least one agent transmits a plurality of state sets related to a state of the environment through a network, receives a plurality of action sets for performing an action, and transmits, to the server, a plurality of feedback messages generated after interacting with the environment. The server configures a predetermined ratio of the memory space as at least one workstation according to the set condition, and selects an untrained model to be temporarily stored in the at least one workstation. The at least one workstation imports a current state set, a current action set, and a current feedback message, as parameters, into the untrained model for reinforcement learning, and generates a next action set until a goal is achieved.

  • Publication number: 20210387331
    Abstract: A three-finger mechanical gripper system is provided, which includes a torque sensor, a three-finger mechanical gripper, an image capturing module and a controller. The three-finger mechanical gripper is connected to the torque sensor. The controller is connected to the torque sensor, the three-finger mechanical gripper and the image capturing module. The image capturing module captures the image of a training object. The controller controls the three-finger mechanical gripper to grip the training object by a plurality of gripper postures respectively and calculates the torque information of each gripper posture according to the measured values of the torque sensor. Then, the controller performs a training process according to the image of the training object and the torque information of the gripper postures in order to obtain a training result of the training object.

  • Patent number: 11143576
    Abstract: A suspension aligning machine includes a bottom board, an intermediate board, a top board, actuation modules, a jig, and a control device. The intermediate board is mounted on a top of the bottom board by first supporting elements and has through holes. The top board is arranged above the intermediate board with supporting elements provided therebetween to have the top board floating and suspending above the intermediate board. The actuation modules are mounted under the top board and respectively extend through the through holes of the intermediate board and form a gap with respect to the bottom board. The operation of the actuation modules causes the top board to vibrate and incline and workpieces deposited in the jig mounted on the top board are caused to move in the jig and fall into the cavities of the jig to line up with each other and thus orderly arranged.

  • Patent number: 10247775
    Abstract: A length adjustable arm and MEMS position detection equipment rotation test apparatus includes an extendible section and first and second rotary bodies provided at one end of a rotation device for variation of a feeding position of a first feeding component so that feeding component is capable of conducting various feeding ways. Further, a worktable is provided thereon with at least one rotation section, which has a surface on which a plurality of operation stations is mounted. As such, through circular change made by the rotation section in respect of the locations of the operation stations, an effect of effectively and efficiently burning or testing can be achieved. Further, the operation stations are provided, on a periphery thereof, with a turning section, and the turning section is operable to turn each of the operation stations in order to effectively conduct tests for various MEMS inertial components.

  • Patent number: 9844885
    Abstract: A gripping device comprises a base, a first finger rotatably or movably connected to the base, and a second finger connected to the base. The first finger and the second finger are capable of selectively entering an opened gripping mode and a closed gripping mode to grip an object. In the opened gripping mode, the first and second fingers grip the object from the same side of the object. In the closed gripping mode, the first and second fingers grip the object from different sides of the object.
