3D操縱杆DIY
這個是德國某( Kosh Naranek)哥們的 DIY 的 3D操縱杆[機械手臂式滑鼠(6軸關節滑鼠/6自由度滑鼠)],
精神極其可嘉,告訴我們并不是所有的高科技觸不可及!!!
普通的電腦滑鼠是一個2D的操作器通過一些界面和電腦連接配接。 Imeinato裝置連接配接到個人計算機是3D操作器通過序列槽連接配接。 這樣操作器的應用包括三維模型,而且遙控機械。 在Sensable Technologies建立模型。
操作器包括以下機械零件: 一個相當重的卡槽底座和三根杠杆(170mm, 88mm, 110mm)由鉸鍊連接配接了。 鉸鍊是電位器,同時擔當分壓器。 安排畫恒定目前并且根據角度線性地劃分電源電壓(5V)。
ATmega88控制器,3個ADC,(如果用絕對光栅超精角度編碼器就有數字的),每一個收發器分别用USART序列槽轉換中間電壓和pc通訊,頻率可達>60 Hz,足以滿足各種應用,用片載ADC實作坐标精确度是 10bit, (1:1024)分辨率。
如果好好設計一下, 效果應該不錯!

passive 3d input device
An ordinary computer mouse is a 2D passive manipulator that connects to PC via some interface. The Imeinato device is a 3D passive manipulator that connects to PC via serial port. Applications of such a manipulator include 3-dimensional modelling, but also remote control of machinery. Get an impression at Sensable Technologies.
The manipulator consists of the following mechanical parts: a fairly heavy socket, and three levers (170mm, 88mm, 110mm) connected by hinges. The hinges are potentiometers, which simultaneously serve as voltage dividers. The arrangement draws constant current and divides the supply voltage (5V) linearly depending on the angle.
A micro-controller (ATmega88) with three analog to digital converters (ADC), and a USART interface converts the intermediate voltages of each divider and transmits it to the PC. The update frequency is above > 60 Hz, which is fast enough for many applications. The precision in the coordinates is restricted by the 10-bit (1:1024) resolution of the on-chip ADC.
Tapio Leppänen has engineered the three cylinders, that attach a lever to a rod of a potentiometer.
Formality... Ritual... You should be informed.
