Abstract: A robot control method, a device, and a remote control system. A mobile terminal establishes 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 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.

Abstract: A dragging demonstration system and method. The dragging demonstration system comprises: a model identification module configured to build a static model of a robot and identify model parameters, wherein the static model comprises a gravity model and a Coulomb friction model; a feedforward compensation module configured to convey the identified model parameters to a current ring of each joint motor of the robot in a feedforward way according to the identified model parameters; and a data recording module configured to record the position information of each joint of the robot so that the robot can repeat the demonstration action. The system and method can make a user push the robot quite easily to implement dragging demonstration.

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.
