I am Robo Zero. It cost around 150,000 yen to make. A brand new, unopened Battery 69 volume is included. It still has the shrink wrap on, so I haven't been able to check the contents. The original battery that was installed is no longer usable and is not included. There are some minor scratches. The accessories are all shown in the photos. You can learn a lot about computers and programming by doing things like programming Awa Odori and climbing a horizontal ladder. I haven't confirmed operation because the battery is unopened and not installed. (It was working until the first battery died.) Therefore, it is being sold as junk.
