Abstract The method of robot teaching by showing considering deforming of the soft tissues is considered in the article. This method is the most natural for inputting to the robot the necessary data of forces and movements. From the point of task setting the control problems considering the information about forces of interacting of robot tool with environment - position, impedance, position-force and compliant control are discussed. For training by showing of the necessary movements with the deforming of soft tissues the new algorithms and biomechatronic compliant modules were developed. The method of teaching "force" points containing the information about assigned forces of soft tissues deforming is a special case. The robot program performs an interpolation for continuous path obtaining after “force” points determination. The program task setting of “force” points is the method drawback. The general spatial case of teaching by showing with the deforming of soft tissues is considered and the layout of force sensors relatively to the handle defining the necessary movement and force is given. This method of showing does not require program setting of necessary forces for deforming of the soft tissues by a doctor. The schemes of training by showing are given for robots containing torque joint sensors or having the ability to determine the joint torque by measuring electric currents of motors. Sharing seance of performing massage mechanotherapy into two phases - training for necessary movements and forces and reproduction of trained trajectory the developed method allows to automate the activities of a doctor, performing techniques of restorative medicine, which is necessary to improve the working ability of the population.
