| The bio-robot (distinct from bionic robot) is a combination of.neuroscience technology, electronic information technology and robot technology, Different from traditional electronic robots, In order to solve power supply problem, bio-robots have been designed to meet our needs in some complicated environment and they have the feature of active energy drive capability. Moreover, difficult environment for human beings and electronic robot such as underground or underwater work might be alleviated by the original ecological body, Since its birth, each country has extensive concern in the development of the bio-robot as a new area of robot. From all the technical means of development to view at present, the bio-robots have been accomplished by delivering stimulations into specific brain regions as steering cues and rewards, and we need to implant stimulating electrodes into the animal brain, which is a hard surgery The bio-robot experiments may not commenced until 5 days。What's more, if the surgery is failed, the animal may die. We can conclude that current bio-robot is an invasive control system via ultrasonic stimulator, epidermal stimulator and LED photic stimulator that has enabled us to remotely deliver stimulation to hearing, epidermal and visual sense of freely moving rat.Firstly, in the introduction part of this paper,we describe the overview of bio-robot research situation and the background issues and research status at home and abroad of bio-robot to explore the biological significance and shortcomings of robotics, and then puts forward to the bio-robot principles and contents of a non-invasive rat and then focuses on hardware and software design of a motion control rat navigation systemThen, the hardware of noninvasive rat navigation consists of the following main components: power supply circuit, an integrated command transmitter, a receiver controller, jacket and head-covering. The command transmitter is comprised of host computer, interface chip, ARMS3C2410 microprocessor and CC1000 transmitter; the receiver controller mainly has ARMS3C2410 microprocessor,CC1000 receiver,stimulator and image acquisition module.Then, the software part is comprised of the port communication software and wireless communication procedures USB interface and serial communication of data for transmission and reception for this design, including parameter setting for ultrasonic stimuli, epidermal stimuli, LED photic stimuli and image data acquisition. At last, in the smooth lawn,we have done the rat navigation experiment including a simple communicate distance experiment testing, the response of the three stimuli to rats testing experiment and the reliability experiment of the remote navigation system .The results indicated that the system worked stably within 300m and the three stimuli are effective for the rats navigation. We can achieve a successful left and right turning control and reach a setting destination.in the aid of the mouse video capture module In a word, the non-invasive motion control navigation system is a good, stable and reliable bio-robot. |
