Control method and control device for drawing robot

The invention discloses a control method and a control device for a drawing robot. The control method for the drawing robot comprises the following steps: acquiring brain wave signal data through a brain wave acquisition module; carrying out analysis processing on the brain wave signal data and generating a control instruction; and controlling the drawing robot to draw according to the control instruction. With the adoption of the technical scheme of the invention, a data acquisition end acquires the bioelectrical signal of a human forehead through the brain wave acquisition module and by virtue of a metal electrode to obtain and analyse the human brain wave data, and control on the drawing robot can be realized by selecting controllable parts in the data through filtering denoising.
