Motor Behavior Regulation of Rat Robots Using Integrated Electrodes Stimulated by Micro-Nervous System

Area of Science:

• Neuroscience and Robotics
• Bio-hybrid Systems Engineering

Background:

• Animal robots offer potential in neuroscience, security, and rescue.
• Reliable control and long-term survival of animal robots remain significant challenges.

Purpose of the Study:

• To develop a bio-friendly neurostimulation system for controlling rat robot locomotion.
• To ensure the long-term survival and reliable operation of animal robots.

Main Methods:

• Integrated electrodes implanted in medial forebrain bundle (MFB) and somatosensory cortex (S1BF).
• Remote wireless stimulation circuit with adjustable parameters (waveform, amplitude, frequency, duration).
• Training rat robots for navigation in a maze environment.

Main Results:

• Successful control of rat locomotion, including forward movement and directional turns.
• Rat robots navigated designated routes in a maze after training.
• Rat robots survived over 20 days with the implanted control system.

Conclusions:

• The developed neurostimulation system enables sustained and reliable control of rat robots.
• This technology provides a foundation for advanced animal robot regulation.
• Potential applications include neuroscience research, national security, and civil rescue operations.
