转化为控制指令，然后每50ms通过串口向上位机发送一次命令，上位机收到数据后控制虚拟仿真机器人，最后，上位机收集虚拟机器人的姿态参数，再通过串-Translated into control commands, and then every 50ms upward through the serial-bit machine to send a command, the data received after the host computer to control the virtual simulation robot, finally, the collection of Virtual PC robot posture parameters, and then through the string

计算机简单控制由软件和硬件组成。软件由Visual Basic 6.0编写。硬件主要由无线发送模块和单片机（C语言编写）构成。通过RS232界面与PC通信而实现无线控制系统。 主要功能是：通过遥控器连接PC机的"上下左右"按键 ,当电脑界面处于powerpoint界面下,能通过遥控器控制幻灯片的上下切换. -Simple control by the computer software and hardware components. Software prepared by the Visual Basic 6.0. Hardware mainly by the wireless sending module and single chip (C language) constitute. Through the RS232 communication interface with the PC wireless control system. Main function is to: Connect PC through a remote control machine up and down about button, when the computer interface in a powerpoint interface via remote control to switch slides up and down.
