A rat robot can be constructed by electrically stimulating specific brain regions to control locomotion and behavior. The makes full use of the rat's motor function energy supply has significant advantages in flexibility, environmental adaptability, covertness. It widely used disaster search rescue, terrain survey, anti-terrorism, explosion-proof tasks. However, existing robots mainly relies on virtual whisker touch produced electrical stimulation barrel area somatosensory cortex reward generated medial forebrain bundle. methods requires substantial experimental training encourage animals match sensation with conditioned reflexes acquired will gradually disappear after a period time at end experiments, which lead decrease stability system. In this study, we developed new method gain inclined movement rats ventral tegmental (VTA) midbrain steering nigrostriatal (NS) pathway. results showed that VTA could induce stable neuromodulatory effect significantly correlated parameters. addition, NS pathway was able directly stably movements head trunk contralateral side stimulated rat. These findings are great importance for robots, especially field environment many slopes. based does not need pre-training while ensuring reliability, greatly improves preparation efficiency certain practical application value.
