As you are using MW Ex you need to use the OnTouching rule of the
turtle backpack.
in that rule you can call a procedure that uses "touchedturtle"
==================================touchedturtle (tturtle)
Reports the name of the turtle that is touched by the one running
this command. Touchedturtle can only be used inside the OnTouching

for example:
if touchedturtle = "t2 [lt 90]

To save an attachment to your computer, PC users should right-click (Mac users, click and hold the mouse button) on the link and then choose 'save target as' from the pop-up menu. A window will then pop up in which you can choose a location for the file.
