I already have it because I found out how to do it, you need to acquire 200 sympathy points (you can check it on the computer in the console where you set the bot at the beginning). You can quickly get points by petting her on the head. After you get 200 points, you have to leave your house for 3-5 days and you will have 3 events and in the last one you will get a stove. All limbs of the bot are required for this.
