未来兔型机器人白云的胸像，绘制于 2017-02-08。白云是我的个人科幻作品“电子之心”的一个重要角色，这张图是他的前期外观设定图之一。白云的前臂是浮空式的，能在距离本体数米内的圆球状空间中独立飞行，因此在此版设定中没有上臂和肩膀部分直接连接躯干。

但是考虑到白云所处时代的条件，我还是考虑在正式设定中不把浮空式手臂作为常态，而是准备一套折叠在浮空手臂内部的物理上臂，在不需要浮空时连接到躯干，以减少不必要的能耗。

在电子之心中，白云将和主角爱理诗一同活跃在未来的世界。

Cloud White is a key character in Electric Hearts. This is one of his early concept art created in 2017. He is supposed to have floating arms, so he has no shoulder in this picture.

However, the world building of Electric Hearts has changed a lot since 2017. I want to limit the technology level. As a result, Cloud’s floating arms can now only fly around closely to his body, and they must connect to his body to charge their batteries.
