近年來機器人被廣泛地運用於人類的生活中,其中服務形的機器人通常涉入於醫療照護,或環境與建築物維護等領域裡。本篇論文的目的為提出一種視覺引導的控制策略,可以運用於服務形的機器人,使機器人能夠驅使機械手臂挾取物體。本文所提出的控制策略為運用延伸的柯漢寧網路模型,將影像特徵與機械手臂姿態,兩者之間的對映關係建立起來。而由於柯漢寧網路有自我學習的特性存在,所以不需要事先校正攝影機的內外部參數。最後藉由雙軸的相機平台與機械手臂,證實了利用雙軸攝影機所獲得的資訊,在經過已經事先學習訓練後的類神經網路,即可精確的定位出機械手臂挾爪的位置。
In recent years, robot technology has widely been utilized in our domestic life. Service robots are gradually involving in medical care, entertainment and building maintenance. The objective of this thesis is to propose a vision-guided control strategy for a service robot to drive its manipulator in the application of grasping tasks. The proposed control strategy is based on the extended Kohonen network and is applied to achieve the mapping between image features and the pose of the robot manipulator. With the characteristic of self-learning, the calibration of the adopted camera is not necessary. A robot manipulator integrated with a pan-tilt camera has been employed to verify the theoretical results of the proposed method. After the training stage, the robot manipulator is able to position its gripper accurately.
