Problems solved by technology

[0004] At present, micro-voltage pulse stimulation and open-loop control methods are used for the control of biological robots at home and abroad. According to the equivalent circuit of the nerve nuclei, nerve nuclei will produce neural fatigue after long-term micro-voltage stimulation, resulting in poor control effects.

Embodiment Construction

[0012] The present invention will be described in detail below in combination with specific embodiments.

[0013] The invention relates to a bio-robot system, which includes an implanted nerve stimulation circuit system and a bio-robot electroencephalogram signal acquisition system.

[0014] Among them, the implanted nerve stimulation circuit system includes a backpack, and the backpack (volume 25×15×2mm, weight 4g without battery, 10g with battery) is composed of a motherboard, FM transmitter and receiver. The backpack was fixed on the back of the rat, and after the rat returned to calm, the microcurrent generated by the C8051F330 chip stimulated the brain nuclei to control the direction of the rat's movement. Since the system needs 3 independent stimulation channels, and the C8051F330 chip has only 1 DAC, we choose analog switches MAX4534 and MAX333A (Maxim Inc.) to realize multiple biphasic microcurrent pulses generated by 1 DAC. figure 1 It is an implantable microcurrent ...

Abstract

The invention discloses a bio-robot system. The bio-robot system comprises an implantable nerve stimulation circuit system and a bio-robot electroencephalogram signal collecting system, wherein the implantable nerve stimulation circuit system comprises a backpack, the backpack is fixed to the back of a rat, and after the rat restores calm, a C8051F330 chip generates microcurrent for stimulating the nuclei of the brain, so that the motion direction of the rat is controlled; during the collecting process, filtering processing is carried out on signals; AD620 is adopted as the pre-amplifier, a band-pass filter composed of the pre-amplifier and an operational amplifier LM324 is placed on a mainboard, a measuring electrode is implanted to an M1 area, a shielded flexible wire is connected with the measuring electrode, the electroencephalogram signals can pass through a 50Hz wave trap before being emitted by QN8027, and the MCU C8051F330 on the mainboard collects the electroencephalogram signals and emits the electroencephalogram signals to a mobile part through QN8027 and a power amplifier circuit. The bio-robot system has the beneficial effects the microcurrent stimulation is adopted for realizing steering, and the system has the independent stimulating or electroencephalogram signal recording function.

Description

technical field [0001] The invention belongs to the technical field of biological robots and relates to a biological robot system. Background technique [0002] "Bio-robots" are also called "cyborgs". The principle is that, according to the neurobiological principles of animal motor behavior, the relevant brain regions of living animals are selected, and the motor functions are combined with modern electronic technology, sensor technology, Network control and other technologies are combined to realize artificial control of animal brain electrical (EEG) signals. Due to the important theoretical and application value of bio-robot research in the fields of neuroscience and engineering, national security, etc., in particular, it has outstanding advantages such as natural concealment, resistance to harsh external (such as lightning, strong wind, etc.) interference, and its own motion energy supply. , has become one of the domestic and foreign frontier research topics that has at...
