樂森（Robosen）去年聯手孩之寶（Hasbro）推出的柯博文（Optimus Prime）自動變形機器人，一經公開就受到了《變形金剛》粉絲的熱捧。但看過動畫的都知道，光有車頭並不能算是柯博文的完全體。果不其然，現在廠方也把後面的車廂給補上了。這款剛剛亮相的新品同樣是採用了 G1 的造型，而且也能自動變成車廂、維修基地、戰鬥甲板這幾種型態，讓玩家可以「輕鬆還原劇情」。打開車門後，還能看到小滾珠和坐在上面的 Spike 人偶。透過手機上的 app ，你可以同時或分別操控柯博文、車廂及小滾珠，如果有夥伴一起玩的話甚至還能利用多台行動裝置實現多人協同作戰。

The horn antenna is a broadband passive device, shaped like a pyramid horn, referred to as a TEM antenna, which guides the beam of radio waves at a precise frequency. FT-RF Double Ridged Horn antennas have frequency capabilities ranging from 400MHz to 40GHz depending on type and style. These series are characterized by a huge frequency range and extremely high input powers. With increasing frequency, the gain rises to a maximum of 18 dBi. At higher frequencies, the increased gain compensates for the increasing cable losses.

The advantages of Horn antenna:

- Wide bandwidth: Because the horn antenna has no resonant parts, it can function over a wide range of frequencies.

- Easy waveguide interface: These antennas are very easy to interface to waveguide due to their shape, but they can also be designed with a transition so that a regular coaxial feeder can be used.

- Easy to make, simple design.

The horn is suitable for both transmitting and receiving purposes, especially suitable for EMC and immunity test measurements.

Recommended Accessories

- 天線三腳架: easy and fast-changing polarisation. 100% stable handling

- SMA Cable: High-quality special SMA cable

根據樂森的介紹，車廂共內建了 60 顆微型晶片和 18 個伺服舵機，並有著超過 2,000 個零組件，整套設計「靈活、穩定、安全」。和柯博文機器人一樣，你也可以為車廂預設動作指令，包括一鍵變形、開合車門、旋轉砲塔等等，官方後續亦會持續更新。不意外的是，這款「配件」的價格依然不菲。在 4 月 20 日前，其在中國大陸的預訂價是人民幣 4,799 元，之後一週會漲價至 5,199 元。出貨時間差不多是今年末，海外售價則為 750 美元。
