    try:
      tty.setraw(fd)
      ch=sys.stdin.read(1)
    finally:
      termios.tcsetattr(fd, termios.TCSADRAIN, old_settings) 
      #print 'error'
    if ch=='i':
      print 'move forward'
    elif ch=='m':
      print 'move back'
    elif ch=='j':
      print "turn left!"
    elif ch=='l':
      print "turn right!"
    elif ch=='u':

    elif ch=='o':
      print "turn right!"
    elif ch=='k':
      print "stop motor!"
    elif ch=='q':
      print "shutdown!"
      break
    elif ord(ch)==0x3:
      #这个是ctrl c
      print "shutdown"
      break
    print "Reading form keybord"
    print """  i

  m"""
    print 'press Q or ctrl+c to quit'
    #rate.sleep()

结果:
