This is a completed toy designed for children.
Here's an adorable Nanoblock RC car that you can also display as Bumblebee! When in car mode, Bumblebee is controllable by downloading an app to your smartphone (how crazy is that?), and it charges up in just a few seconds, running for about 2 minutes on a charge. The charging base is included, and it requires 2 AA-size batteries, not included.
