机械蛇赤练灵曦 (Lucia Scarlet)，这是个人原创作品“电子之心”系列的前期概念设计图之一。

灵曦是一条大型机械蛇，腹部是履带，背部可以装载乘员和各种规格的集装箱，承担着在雪原上为各个联络点运输物资和人员的工作。

灵曦的头部可以灵活旋转，蛇牙是吊钩，可以自行吊装集装箱。蛇信是一个工具套筒，可以更换多种批头、焊枪等工具，进行一定程度的自我检修。

灵曦的躯体是多节的，每节躯体一组履带，每组又分为左右两条履带，每条履带均可按照独立的方向和速度运转，赋予了灵曦相当灵活的移动能力，她能够以各种匪夷所思的姿势通过某些看上去难以踏破的险境。尽管理论上灵曦可以无限延长自己的躯体，但生产的躯体节段有限，不能支持她实现“无限贪吃蛇”的想法。

灵曦离开基地远行时可以选择挂载不同的供电模块，包括：

占用 1 节空间的核电池——每个核电池每天可支持 12 节的身体配置以中等载荷行驶 4 小时，如果有乘员和设备蹭电，则续航会进一步降低，且无法提供高功率电源输出。通常挂载 2 – 3 组。

占用 2 节空间的放射性同位素热电机 (RTG)——可支持 12 节的身体配置以中等载荷无限时间行驶。对于乘员和设备蹭电也能提供更高功率的电源输出。

占用 3 节空间的核反应堆——基本没有用电限制。通常只在带队进行雪原发掘工程时挂载，作为队伍的供电中心。灵曦不喜欢使用三节核反应堆，因为它会让三节身体无法弯折，而且非常沉重，会严重影响她的灵活性和在雪原上的安全性。

“赤练灵曦”这个名字和红黑白三色的配色本来是属于我多年前画的一个海豚型兽人的，她的原案是我投稿给 2008 年奥运会吉祥物海选的方案之一。后来因为觉得海豚除了看上去可爱之外没有太多其他有趣的特性可以挖掘，而且也对不上“赤练”这个姓，就把她改成了一条蛇。

This post showcases the concept arts of Lucia the Robot Snake. This set of pictures are the early concepts of Electric Hearts.

Lucia is a huge robot snake. There are tracks under her body that allows her to move on the snowfield. She can carry passengers and containers on her back. She delivers people and supplies to the stations on snowfield.

Lucia’s head can rotate around with ease. Her fangs are lifting hooks. She can load and unload 1-unit containers on her own. Her tongue is a socket wrench with swappable tool bits and welding gun. She can carry out self-maintenance to some extent.

Lucia has a multisection body. Each section has a set of 2 tracks that can move in its own direction and speed. This gives her strong off-road ability to run across seemingly impossible terrains. Although there is no limit of how many body sections Lucia can have, but only a limited number of body sections were manufactured.

Lucia can choose from a few different power source units when she is out in the snowfield:

1U Atomic Battery – Each requires 1 payload space, Lucia would typically carry 2 to 3 units. Provides enough power for a 12 sections body configuration to traverse the snowfield for 4 hours under moderate load, every day. Endurance drops as power distributed to passengers and equipments.

2U Radioisotope Thermoelectric Generator – Each requires 2 payload space. Provides enough power for a 12 sections body configuration to traverse the snowfield for unlimited time under moderate load. Can also distribute more power to passengers and equipments.

3U Portable Nuclear Reactor – Each requires 3 payload space. Unlimited power supply. Typically used when Lucia works as an exploration team’s main power supply. Lucia dislikes the 3U reactor unit because of it make her clumsy on the snowfield – it locks up 3 sections of her body, and it is very heavy and wide. It often gets in the way of things, and the extra weight makes her more susceptible to fall into hidden snow pits.

The name “Lucia Scarlet” was initially used on one of my dolphin character – she was the mascot candidate I submitted to the 2008 Beijing Olympic Game mascot contest. Over the years, I found the idea of a dolphin character not very interesting except for being cute. The first name “Scarlet” in Chinese means “Red Ribbon”. So I decided to give the name to a red robot snake instead. I think Lucia as a snake has more potential to be an interesting character.
