This research was stemmed from a project sponsored by Employment and Vocational Training Administration, Council of Labor Affair, Executive Yuan, Taiwan, to build a low-cost yet effective VR environment for training and licensing. This project successfully built three types of interactive visual simulators, which include a stereo-vision mobile crane simulator, a cabin-based crane simulator, and a stroll-based overhead crane simulator.

(a). Mobile Crane Simulator

● The functional architecture of the mobile crane simulator includes six modules (as depicted below): I/O control module, instructor monitor, scenario control module, dynamics module, visual display, and audio modules. Furthermore, the I/O control module consists of two sub-modules, which are Dashboard module and Motion platform controller.

● The first generation crane simulator was built on a hydraulic-driven three-axes Stewart motion platform.

 

● The second generation crane simulator was built on a power-driven six-axes Stewart motion platform.

(b). Overhead Crane Simulator

● This research designed a locomotion mechanism called Omni-directional Ball-bearing Disc Platform (OBDP), which allows the user to walk naturally on it and thus to navigate the virtual environment. A gait sensing algorithm that simulates the user's posture based upon his footstep data collected from the OBDP was then presented. An overhead crane simulator was thus constructed based upon the gait sensing algorithm on OBDP. No other sensor, except the head tracker to detect the user's head rotation, is required on the user's body.

叢集式視覺化即時動感模擬

  此項研究的緣起是應行政院勞委會勞工安全衛生研究所的委託,設計了三部不同的起重機訓練模擬系統, 此起重機訓練模擬系統的研發目的是要發展兩類型的起重機訓練模擬系統:固定式與移動式,而此兩種模擬器皆是以黃老師所開發之叢集 式視覺化即時模擬平台來架構所需之電腦系統。本計畫為整合型計畫,參與單位包括成功大學機械系、元智大學機械系、台中精機公司、 淡江大學機械系及黃老師所帶領的研究生團隊。主要工作包括:()、起重機操控艙機構設計;()、三軸及六軸動感平台之設計;()、固定式鋼珠平台之設計;()、虛擬實境系統及模擬場景之設計;()、模 擬器系統架構之機電整合;()、多媒體訓練教材的設計。其中,黃老師的實驗室團隊負責第四項及第五項的工作。 

(a). 移動式起重機訓練模擬系統

●  整體起重機模擬器的模擬流程如下圖所示,包含了六個模組,分別為輸出入裝置控制模組(I/O control module)、起重機狀態監控模組(instructor monitor)、訓練劇本控制模組(scenario control module)、動力學模組(dynamics module)、視覺模組(visual display)及音效模組(audio modules)。在輸出入裝置控制模組中,包含了兩個子模組分別 為儀表板控制模組(Dashboard module)及平台控制模組(Motion platform controller)

●  第一代模擬器是使用油壓驅動之三軸式『史都華』動感平台

 

●  第二代模擬器是採用電動六軸式『史都華』動感平台
