| Gecko animal-robot uses gecko's ability moving on the ceilings and walls to make up for gecko bionic robot's disadvantage in mobility and adaptability. The research on gecko animal-robot could be divided into two parts: finding gecko's brain function to control its action and designing a remote simulating system. This article provides a scheme of the remote simulating system, and presents the method about its hardware and software design. The system, which is based on BCI, could be divided into controlling platform and micro-stimulator. And the controlling platform makes up of s PC, a MCU and a wireless transceiver chip to transmit the command. The micro-stimulator makes up of a MCU and a RF transceiver, which receives the command and make a simulating signal to remote the gecko.Firstly, the thesis introduces the development and current situation of animal-robot and its remote system, shows the scheme of gecko animal-robot. Then hardware design and software design of the simulating system are introduced. Hardware design includes the power circuit, serial communication circuit, the smallest system of ATmega8 and the external circuit of RF Transceiver. Serial communication program, wireless receiving program, wireless transmitting program and the program to produce the simulating signal are introduced. At the same time, the work on improvements of the wireless communication and the simulating signal are introduced. Finally, the thesis shows the performance of the system in the experiments, gets a summary and presents the future work.The experiments testified that the remote simulating system for gecko animal-robot was convenient, practical. And the micro-stimulator gets the signal,outputs a control signal,regulates gecko animal-robot'behavior.The remote control device is light, and could be carried easily. |
