  • Publication number: 20230356345
    Abstract: A multi-type industrial robot control system may include: an automation controller; and a programmable logic controller (PLC)-robot bridge. The controller stores a general-purpose robot control function block generated using a unified design standard, calls a corresponding robot control function block for a robot and using robot state data and puts out corresponding first command data to the PLC-robot bridge. The PLC-robot bridge virtualizes robot interfaces of corresponding offline programming functions of different types of robot as a unified virtual interface, calls a corresponding offline programming function via the unified virtual interface according to the first command data, and generates second command data for output to a corresponding robot controller. The corresponding robot controller controls a corresponding robot. At the same time, robot state data from a corresponding type of robot is received via the unified virtual interface and the robot state data is fed back to the automation controller.

  • Patent number: 11732149
    Abstract: The present invention discloses a hybrid (mixed) formulation composition for 3D additive manufacturing and a manufacturing process. The hybrid formulation composition possesses capability of UV radiation curing and thermal curing. The hybrid formulation composition is designed to be cured by UV radiation in the 3D printing/additive manufacturing process and then post cure by heat to get its final properties. The hybrid formulation composition consists of acrylates (oligomer, monomer, and diluent), photoinitiators, and isocyanate-containing prepolymers which comprises polyols (di-ol, tri-ol) and isocyanates. The hybrid formulation composition may also include reaction accelerator, dye, pigment, and fillers. The finished products of the hybrid formulation composition possess rubber-like properties and can be used in the applications such as shoe sole, toys, medical, and wearables goods . . . etc.
