  • Publication number: 20230321819
    Abstract: The present application relates to the technical field of robots, and discloses a robot control method based on a physical engine. The method includes: obtaining the current first resultant force to which a robot is subjected and the current second resultant force to which a virtual object in a virtual environment constructed by a physical engine is subjected; determining the current motion information corresponding to the current first resultant force and the current second resultant force according to the corresponding relationship between the force and the motion information; wherein the current second resultant force is determined by the physical engine according to the previous motion information corresponding to the previous first resultant force of the robot and the previous second resultant force of the virtual object, and the current motion information enables the current first resultant force and the current second resultant force to tend to be synchronized.

  • Patent number: 8134022
    Abstract: The present invention relates to a polyether carbonate polyol made by copolymerizing a starter molecule with carbon dioxide, at a pressure ranging from about 10 psia to about 2,000 psia, and an alkylene oxide, at a temperature ranging from about 50° C. to about 190° C. and in the presence of from about 0.001 wt. % to about 0.2 wt. % of a substantially non-crystalline double metal cyanide (DMC) catalyst, wherein the polyol has an incorporated carbon dioxide content of from about 1 wt. % to about 40 wt. %, wherein the ratio of cyclic carbonate by-product to total carbonate is less than about 0.3 and wherein the weight percentages are based on the weight of the polyol. The inventive polyether carbonate polyols may find use in producing polyurethane foams, elastomers, coatings, sealants and adhesives with improved properties.

  • Patent number: 6664360
    Abstract: Alkoxylated acrylate and methacrylate macromonomers are disclosed that are useful in the preparation of water-reducing additives for concrete, ultraviolet light-curable adhesives, and water-dispersed polyurethanes. The macromonomers are suitably prepared by alkoxylating a hydroxyalkylacrylate or hydroxyalkylmethacrylate in the presence of a DMC catalyst using the continuous addition of starter (CAOS) in order to prevent the formation of by-products during the fabrication of the macromonomer.

  • Patent number: 5990232
    Abstract: Unique, well defined polyethers containing both hydroxyl-functionality and unsaturation-functionality are prepared by oxyalkylating an unsaturated monomer having at least two free carboxylic acid groups in the presence of an effective amount of a double metal cyanide complex catalyst, optionally, when necessary, in the presence of a free radical polymerization inhibitor. The resulting polyethers are eminently suitable for such uses as polymer polyol stabilizers or stabilizer precursors, and both in situ and ex situ impact modifiers for thermoplastics.

  • Patent number: 5786514
    Abstract: A process for alkoxylating phenols is disclosed. The process comprises reacting a carbonyl-functionalized phenol with an alkylene oxide in the presence of a substantially non-crystalline double metal cyanide (DMC) catalyst. The process offers fast reaction times at low catalyst levels, reduced problems with condensation side reactions, and low-color, low-viscosity, low-polydispersity alkoxylated phenols. The process enables efficient preparation of alkoxylated carbonyl-functonalized phenols that are especially valuable in the surfactant industry.
