| This thesis describes a vision grab and transmission system for microrobots based on 32-bit ARM microcontroller from the aspects of hardware and software, and present USB transmission methods onμC/OS-II and ARM micro controller. In addition, a GUI interface that can receive image from USB port and update the image was realized.CMOS Sensor has been used in the Microrobot Vision System, with wireless transmitting and USB interface, which is innovative in design, flexible in application and stable in performance. nRF wireless technology is a Short Range Wireless transceiver that aimes to realize the 2.4GHz wireless application. It supports multipoint communication and receives the data from two different channels at the same time.This thesis mainly explicates the theory of system realization and processes of the software and hardware realizations from the perspectives of wireless data transmission and USB interface system. The hardwares include the modules of power supply, signal acquisition, high-speed wireless multi-channel, USB interface, etc. The softwares include wireless data transmission, USB firmware, WDM driver procedure as well as upper PC application program. Based on the schematics of circuit design, the thesis addresses the anti-interference treatment and the preliminary debugging of the system. It can be concluded from the application that this data transmission system is characterized by low cost, small shape, easy operation and upgrading convenience of the firmware. |
