Bb-8 remote droid has all the parts. It’s the biggest version they made, almost 1:1 in size. Needs new rechargeable batteries installed. It’s not an easy job and will require some skill and patience. All these droids had dead batteries after 1 year and are not user friendly to replace, but it is possible. Lots of online resources. I was going to do it but can’t be bothered at the moment.
