Robot and system thereof, preparation method of robot and motion control mode of robot

The invention relates to a robot, a robot system, a preparation method of the robot and a motion control mode of the robot. The preparation method of the robot comprises the following steps: mixing a thin film material and magnetic particles to prepare a base film; cutting the base film according to a preset shape to form a semi-finished product; and the semi-finished product is placed in a preset magnetic field to be magnetized, and the robot is formed. The motion control mode of the robot comprises the steps that a three-dimensional Helmholtz coil is built to form a working space, and a control magnetic field is obtained in the working space after electrification; the control magnetic field enables the robot to respond to obtain response information; the response information is captured by the camera and transmitted to the computer; the computer displays response information and sends a control signal to the motor controller through a driving control program; and the motor controller generates current and t
