Method for controlling animal robot to turn on basis of ventral posterior medial nucleus electrical stimulation

Abstract

The invention relates to a method for controlling an animal robot to turn on the basis of ventral posterior medial nucleus electrical stimulation. The method comprises the steps that two stimulating electrodes are respectively imbedded into VPM (Ventral Posterior Medial Nucleus) regions on both sides of the animal robot, the electrodes are fixed on skulls with dental cement, and an electrical stimulation backpack is installed on the animal robot; waveform parameters of electrical stimulation are set by an upper computer and are transmitted to the electrical stimulation backpack at the back of the animal robot in a wireless mode, the stimulating electrodes are controlled by the electrical stimulation backpack, so as to perform electrical stimulation on the animal robot, and corresponding thalamus-cortex projection loops are activated, so that the animal robot generates a virtual feeling, so as to complete turning. According to the method, a traditional method that the animal robot learns to turn by reward training is eliminated, turning is realized directly through the electrical stimulation, the controllability over a turning angle is realized, a large amount of training time is saved, the working efficiency is high, and the method has good application prospects in the field of animal robot navigation.

Description

technical field [0001] The invention relates to an animal robot, in particular to a method for controlling the steering of an animal robot based on the electric stimulation of the ventral posterior intermediate nucleus of the thalamus. Background technique [0002] "Animal robot" refers to the use of the animal's motor function and power supply system, starting from the transfer of the animal's feelings or innervation, to realize the control of the animal's movement and certain behaviors. In recent years, with the development of brain-computer interface (Brain-Computer-Interface, BCI) technology, it has been realized to directly intervene in the brain of animals through external stimuli. Implanting microelectrodes in specific areas of the animal's brain provides electrical stimulation, allowing the animal to produce virtual sensations, including reward, fear, and touch. Because this electrical stimulation is controllable by humans, humans can control animals to produce thes...

AI Technical Summary

Problems solved by technology

If the navigation task takes up a lot of training time, it will inevitably reduce the application range of animal robots (rats)

On the other hand, the learning ability of rats is limited. If rats are allowed to learn too many things, it will inevitably increase the difficulty of realizing animal robots (rats).
