Did you use Q_INIT_RESOURCE? And use slashes instead of back slashes.

use "/" as directory separator; if you insist on "\" you must at least escape the "\" properly

QPixmap map(":/images/robot1.png");
it did not work,how to use Q_INIT_RESOURCE,
i added code in main(),but

QApplication a(argc, argv);
Q_INIT_RESOURCE(a);

there is a error "1>main.obj : error LNK2019: unresolved external symbol "int __cdecl qInitResources_a(void)" (?qInitResources_a@@YAHXZ) referenced in function _main"

,how to use Q_INIT_RESOURCE

This is all described in the docs. Please read them!

i write code as doc,added Q_INIT_RESOURCE(a),but it did not work.

int main(int argc, char *argv[])
{
....
QApplication a(argc, argv);
Q_INIT_RESOURCE(a);
....
}

My enviroment is msvc in windows

I have supposed that, but what I have meant is, what file name has you qrc file. And how to alter your pro file, you can read in the docs under the topic "The Qt Resource System" (-> RESOURCES)...
