The invention provides a heterogeneous master-slave teleoperation control method and device based on force guidance. The method and device consider that the current position tracking between a masterarm and a slave arm is easily affected by a system signal when the position tracking is realized through position control, and when the system signal is discontinuous, the smoothness of the teleoperation is significantly affected, and the slave arm is damaged in severe cases. Therefore, in the master-slave teleoperation control process, a slave arm target position is generated according to masterarm end position information and slave arm end position information in a preset period, the slave arm target position is compared with a slave arm real-time position to determine a position error between the master arm and the slave arm, and then the position error is converted into a virtual elastic tension to realize the transformation from the position tracking to the force control. Moreover, since the discontinuity of the force only causes acceleration jumps and slow changes in speed, the motion of the slave arm is always continuous and smooth, and the damage to the slave arm is not caused.
