Free Roomba virtual walls & remote. I got these from someone about a year ago, and haven’t did anything with them. Yours if you want them, just have to pick them up within 2 days of claiming or they go to the next person on the list. I live 5 minutes from the Hackerspace, so I can meet you in the evening.
These work with the 400 series and below. But might be worth a good hack to take out the IR circuitry and do something with it.
Let me know if you want them.
