Abstract: A control method of the composite robot includes acquiring multiple forces and multiple torques collected by the force sensor in the current motion when the robot arm is pulled to move; calculating multiple displacement value sets according to the multiple forces, the multiple torques, a preset desired force, a preset desired torque, and a preset model; calculating the optimal solution according to the multiple displacement value sets to obtain a first target displacement value corresponding to the robot arm and a second target displacement value corresponding to the motion mechanism; controlling the robot arm and the motion mechanism to move according to the first target displacement value and the second target displacement value; and repeating the operation of acquiring multiple forces and multiple torques collected by the force sensor in the current motion until the robot arm and the motion mechanism stop moving.

Abstract: Embodiments of the disclosure provide a nucleic acid extraction microfluidic chip, and a nucleic acid extraction device and method. The nucleic acid extraction microfluidic chip includes a channel plate including: a mixed lysis zone, an extraction zone adjacent to the mixed lysis zone, a gas-pressure driven port in communication with an exterior, a first type of channel communicating the mixed lysis zone with the extraction zone, and a second type of channel communicating the extraction zone with the gas-pressure driven port; a cover plate opposite to the channel plate, wherein the cover plate includes a sample inlet and a liquid inlet through hole in a location corresponding to the mixed lysis zone; and a solution accommodating cavity, on a side of the cover plate away from the channel plate, wherein the solution accommodating cavity communicates with the mixed lysis zone of the channel plate through the liquid inlet through hole.

Abstract: A detection device and method for detecting a protein-based marker, and method for manufacturing a chip are provided. The detection device includes a first cover plate, in which a liquid inlet and a liquid outlet are provided; a second cover plate attached to the first cover plate to form a chamber; and a chip in the chamber. The chip includes a glass substrate and a micro-hole array layer on a side of the glass substrate. The micro-hole array layer includes a plurality of micro-holes arranged in an array, with each of the micro-holes being a nano micro-hole. The liquid inlet and the liquid outlet are configured such that a solution containing a plurality of magnetic particles enters the chamber via the liquid inlet, flows through at least a portion of the plurality of micro-holes of the micro-hole array layer, and discharges from the liquid outlet.

Abstract: A robot control method, a device, and a remote control system. A mobile terminal establishes a connection to a robot by scanning a two-dimensional code and by a local area network. A remote monitoring and control center connects to the mobile terminal by a wide area network, and when the mobile terminal and the remote monitoring and control center send information to each other, the mobile terminal breaks off connection with the robot, thereby ensuring information transmission security. Operation instruction information from a user on an operation interface is acquired, the operation instruction information comprising a control parameter and an action execution parameter, and on based on the set control parameter and the set action execution parameter, first control instruction information is generated, and sent to the robot by a wireless communications network, in order to cause the robot to execute a corresponding action based on the first control instruction information.
