How about a personalized robot building kit? You could find a company that offers custom designs and have them create a robot that resembles your wife or has special meaning to your relationship. Another idea could be to purchase tickets to a robotics exhibition or conference that she's interested in attending. You could also consider enrolling her in a robotics workshop where she can learn how to build and program robots. If she enjoys reading, you could purchase a book about the history or future of robotics, or even a sci-fi novel with robotic characters. Lastly, you could surprise her with a high-tech gadget or smart home device for the both of you to enjoy.
Or you can get her a star map with the date of your anniversary.
