What kind of robot do you have ?

In my case, I use Logicool c920 webcam and iRobot Create wheelbase.

I use Fiducials (some marker pattern) for the robot to recognize me. I print out the arrow marker and carry it. Then the robot will follow me. In RoboRealm, I need to run Fiducial module, set Min Confidence from 30 to 80, tick the Create Fiducial Array, press Train, then OK. Then run the irobot create module. Then run the VBScript module. The VBScript is like this:

speed = 30
keep_distance = 7
halfwidth = GetVariable("IMAGE_WIDTH") / 2
fiducials = GetArrayVariable("FIDUCIALS")
names = GetStrVariable("FIDUCIALS_PATH")
if isArray(fiducials) then
  if ubound(fiducials) > 0 then
    for i=0 to ubound(fiducials)-1 step 17
      nstart = fiducials(i+15)
      nend = fiducials(i+16)

      NameNow = mid(names, nstart+1, nend-5)

      if NameNow = "arrow" then
        ArrowSize = fiducials(i+11)
        ArrowX = fiducials(i+9)
        if ArrowSize < keep_distance then
          leftMotor = 128 + speed * (ArrowX / halfwidth) + speed
          rightMotor = 128 - speed * (ArrowX / halfwidth) + speed
        else
          leftMotor = 128
          rightMotor = 128
        end if
      end if
    next
  end if
end if
SetVariable "LEFT_MOTOR", leftMotor
SetVariable "RIGHT_MOTOR", rightMotor

That's it!
