Control system for intelligent biomimetic expression robot based on facial muscle neural network
View Patent ↗A control system for an intelligent biomimetic expression robot based on a facial muscle neural network, including a support body, a power module, a control module, a muscle neural network, and an expression generation body. Second sensors are connected to the grid conductor. Drive units are distributed and connected at the intersection points within the grid conductor, and the ends of the grid conductor are electrically connected to first output ports. Under the control of control units, the drive units generate driving forces. The first sensor is configured to detect the longitudinal forces generated by the drive units, while the second sensor is configured to detect the horizontal force generated by the drive units. When the first output port applies the power difference through the grid conductor to the drive units, the power difference between adjacent drive units continuously changes, thereby causing the deformation zone to undergo continuous deformation.
