Abstract: A steerable drilling device has an outer tube extending along a longitudinal axis; a drill bit joint inserted into said outer tube, a lower end of said drill bit joint extending out of a lower end of said outer tube for connection to a drill bit; a joint drive mechanism, provided in said outer tube and configured to drive said drill bit joint to swing relative to the longitudinal axis; and a lower connection mechanism. The lower connection mechanism has a connection body connected to said joint drive mechanism in such a manner that said joint drive mechanism is non-rotatable with respect to said connection body, a first centralizer arranged between said connection body and said outer tube, a circuit system arranged in said connection body and configured to provide an electrical signal to said joint driving mechanism, and an attitude sensor arranged in said connection body.

Abstract: Embodiments of present disclosure relates to a robot and method for sewing an object. The robot includes a first robotic arm adapted to hold a needle, the needle carrying a length of a thread, a second robotic arm adapted to hold the needle, and a controller configured to move the first and second robotic arms to perform a plural of sewing operations so as to form a plural of stitches on the object A sewing operation includes moving the first robotic arm a first distance to cause the needle to penetrate a part of the object; and moving the second robotic arm to hold a penetration portion of the needle and pull the whole needle out of the object after the needle being released by the first robotic arm.

Abstract: Disclosed is a carbon-dioxide-responsive self-thickening intelligent fluid based on supramolecular self-assembly, which comprises a Gemini surfactant, a single-chain amide molecule having a tertiary amine head group and water, wherein the Gemini surfactant and the single-chain amide molecule are self-assembled to form a vesicle structure dispersed in water, with a hydrophilic head group being located outside and a hydrophobic tail group located inside. The method for preparing the carbon-dioxide-responsive self-thickening intelligent fluid of the present invention is simple, the injection viscosity is low, and the fluid is converted into a gel when encountering carbon dioxide, so that the viscosity is greatly increased.

Abstract: A test method and device for a contact resistor are provided, configured to test a contact resistor of a metal-oxide-semiconductor (MOS) transistor. The method includes: a resistance value per area and a temperature coefficient of resistance of the contact resistor are acquired; and a target resistance value of the contact resistor is determined according to the resistance value per area, the temperature coefficient of resistance, and an area of the contact resistor.

Abstract: A parking assisting method, device and system for a motor vehicle are provided. The parking assisting method includes the following steps: obtaining a relative position of an available parking spot relative to the motor vehicle; outputting a display instruction to the digital projector according to the relative position of the available parking spot relative to the motor vehicle; and projecting a projection image to the available parking spot by the digital projector according to the display instruction. The projection image is provided for indicating the available parking spot area will be occupied. The display instruction includes an image position for the projection image, so as to change the position of the projection image in the projection range, so that the position of the projection image in the available parking spot is substantially kept unchanged.
