SPHERO玩具的乐趣来自其神秘的性质：它有没有按键，没有电池盖，没有充电器的插座。摇一摇，全球发光与颜色的光。
把它放在地板上，呼叫控制中的应用在智能手机，SPHERO反弹到生活，围绕在屏幕上的虚拟摇杆的方向上艰难跋涉。
130美元的SPHERO是由伊恩·伯恩斯坦和亚当·威尔逊公司最初成立销售基于蓝牙的其他设备制造商的控制技术，Orbotix。
但伯恩斯坦和威尔逊表示，他们的技术，最好的广告是一个产品，一个随之而来的深夜头脑风暴会议产生的SPHERO。
A.充电座，球停留在码头，使用了感应系统，送电，SPHERO的两个锂聚合物电池。一个完整的充电大约需要3小时75分钟的连续驾驶时间。
B. 轮，两个独立控制的橡胶镶边轮毂内的SPHERO引导和推动球速度高 ??达每秒1.2米。
C. 顶端滑轴承由于内部机制内部的塑料的情况下，该轴承支撑机制在必要时，可以自由移动，以保持SPHERO的轮子与外壳紧密接触。
D. 印刷电路板的处理器从一个三轴加速度计和陀螺仪SPHERO的侧倾，俯仰和偏航，以产生精确的测量数据相结合。这些测量需要无线电的智能手机通过蓝牙连接的命令作出正确的反应。
E. 蓝牙无线电和天线系统，最大射程超过50米，在最佳条件下，用于与移动设备通信。开发人员可以下载一个软件开发工具包从Orbotix和写自己的iOS或Android控制应用的SPHERO。
F. 多色LED，与红色，绿色，和蓝色的元素从一个单一的LED封装件的光扩散，由透光性的壳体，使SPHERO辉光。不同颜色的信号的信息，如设备是否被充电或当电机转速正被暂时提升。用户可以选择的颜色的智能手机应用程序的方式。

Much of the fun of the Sphero toy comes from its mysterious nature: it has no buttons, no battery cover, no socket for a charger. Shake it and the globe glows with colored light. Put it on the floor, call up its control application on a smart phone, and the Sphero springs to life, trundling around at the direction of an on-screen virtual joystick. The $130 Sphero is made by Orbotix, a company that Ian Bernstein and Adam Wilson originally founded to sell Bluetooth-based control technology to manufacturers of other devices. But Bernstein and Wilson were advised that the best advertisement for their technology would be a product; a consequent late-night brainstorming session spawned the Sphero.
A. Charging Dock
The ball rests in a dock that uses an induction system to transfer electricity to the Sphero’s two lithium-polymer batteries. A complete charge takes about three hours and provides 75 minutes of continuous driving time.
B. Wheels
Two independently controlled rubber-rimmed wheels inside the Sphero steer and drive the ball at up to 1.2 meters per second.
C. Top Slip Bearing
Because the internal mechanism can move freely inside the plastic case, this bearing braces the mechanism when necessary, in order to keep the Sphero’s wheels in firm contact with the shell.
D. Printed Circuit Board
A processor combines data from a three-axis accelerometer and a gyroscope to produce the precise measurements of the Sphero’s roll, pitch, and yaw. These measurements are required to respond correctly to commands radioed by a smart phone over a Bluetooth connection.
E. Bluetooth Radio and Antenna
This system, with a maximum range of over 50 meters in optimum conditions, is used to communicate with mobile devices. Developers can download a software development kit from Orbotix and write their own iOS or Android control applications for the Sphero.
F. Multicolor LED
The light from a single LED package with red, green, and blue elements is diffused by the translucent casing to make the Sphero glow. Different colors signal information such as whether the device is charging or when the motor speed is being temporarily boosted. The user can select the colors by way of the smart-phone application.
