Abstract: 摘要:工研院機械所的調查報告指出,未來市場最被看好的五款機器人分別為Cleaning Robot、Security Robot、Reception Robot、Childcare Robot、Intelligent Wheelchair 等, 均為輪式移動機器人,市場價值於2010 年將達1.8 trillion。為了使移動式機器人成為 服務性智慧機器人合用的載具,以及利用此種機器人進行車輛行駛自動控制的研究, 並使自動導引系統更具強健性,並得以適應於不同的環境,本計畫將針對一實驗用的 小型移動式機器人,Dr Robot X80,先進行追跡控制,再利用人工智慧進行路徑規劃, 最後再利用DSP 及一組多功能的FPGA 晶片組,將控制律的運算及系統週邊的感測 器輸入輸出控制轉換成邏輯電路,以為將來自動駕駛控制器奠定理論及硬體商品化之 基礎。以台灣在IC 電子製造業的優勢,期望將來能設計製作出具有市場競爭力之智 慧型移動式機器人或車輛自動導引控制器。本計畫分三年來完成智慧型移動式機器人 運動控制的理論分析、軟體模擬及硬體實現。第一年係應用模糊理論並結合基因演算 法,針對追跡控制設計模糊控制器,已完成追點、追線及追圓的軟體模擬追跡控制, 並以Dr Robot X80 實現硬體驗證。目前正執行第二年計畫中,已完成利用超音波感 測元件並結合模糊系統於路邊停車及倒車入庫之自動控制。目前正應用簡易型室內定 位系統,進行定位點精度修正,並利用可即時學習的類神經網路與小腦模型控制器並 結合不同的演化計算法則,進行移動式機器人的即時學習及控制。第三年則將結合視 覺與雷射感測元件進行路徑規劃與避撞控制,簡化影像處理技術與探討最佳化路徑規 劃及硬體控制器的實現。
abstract:According to the ITRI report, the top five demands of robot industry in the future are Cleaning Robot, Security Robot, Reception Robot, Childcare Robot, and Intelligent Wheelchair. They are all Wheeled Mobile Robot (WMR). The market value will be 1.8 trillion in the year 2010. In order to make the WMR a suitable carrier for multiple purpose services, this project will put focus on automatic guidance control. Robust and adaptive control will also be addressed. This project will investigate the control problem using an experimental WMR setup, Dr Robot X80. Trajectory tracking control will be first investigated. Path planning that uses artificial intelligent techniques will then be applied. This research will also integrate different sensors to trajectory tracking, shortest distance search, collision avoidance, and automatic parking control. Finally the control law and I/O interface will be transformed into logic circuits and be implemented on a multiple purpose Field Programmable Gate Array (FPGA) set. The feasibility of the proposed commercialized intelligent automatic control system will be evaluated by the hardware test. This is a three-year project and there are three phases: theory analysis, software simulations, and hardware integration and test. At the first year, we have applied the fuzzy reasoning capability of the fuzzy system and the parameter predicting and searching ability of the genetic algorithm to the trajectory tracking control design. Software simulations and hardware experiments on tracking setpoint, line and circle are accomplished Currently we are working on the second year’s project. By utilizing ultrasound sensor and fuzzy system, automatic control of parallel parking and garage parking are performed successfully. A local positioning system called the Star Gazer is applied to reduce the position error of the WMR. During the second year, Recurrent Neural Network (RNN) and Cerebellar Model Arithmetic Controller (CMAC) with different evolutionary computations will be utilized to the real-time learning and control. In the third year, different sensors such as CCD camera and laser ranger will be integrated in the control scheme. Optimal path planning and collision avoidance control will be studied. Hardware controller will be implemented in a DSP/FPGA module.
