柔性臂機械人被廣泛應用於航天航空業,製造業,核電廠,軍事,醫療器材和農業等各方面的機械設備。其中一種柔性臂機械人 ── 連續體機器人更是廣泛被應用於微創或無創手術機械人作機械手之用。 ; 本文提出以小尺寸連續體機器人可用於手術機械人中以協助醫生完成各無創手術,並以我們研發的手術機械人為例以協助醫生完成內黏膜下剝離術。我們探討了小尺寸連續體機器人的模型並分析其運作。小尺寸連續體機器人是由一個推挽機構致動,推挽機構於連續體機器人後方拉動形狀記憶合金線,前方的連續結構會以對應的彎曲運動實現控制的指令。 ; 現今常用於簡化連續結構模型的假設是假設連續結構上每一小段的曲率皆是相同。雖然連續部分的運動學模型和靜態模型是可預測,但連續的機器人是一種柔性的結構,其基於運動學模型控制的精確度是低的。我們亦不能完全以數學方式模擬所有連續體機器人的動作。因此,本文提出了使用回饋實際彎曲角度和理想彎曲角度的差距以實現連續機器人的精確閉環控制。根據我們提出的閉環控制,小尺寸連續體機器人的平均誤差可大幅減少。 ; Flexible manipulator is extensively used in various robotic applications, for example, aerospace and outer space industries, manufacturing industries, nuclear plants, military, surgery and agriculture. Specifically, continuum structure is a type of flexible manipulators widely adopted in minimally invasive surgical (MIS) applications. This dissertation presents the modelling and analysis of a continuum robot, which has tendon-sheath mechanism at the front end and the continuum section at the distal end, in an assistive robotic system. One of the application of the assistive robotic system is supporting Endoscopic submucosal dissection (ESD). The small size continuum section is actuated by a push-pull mechanism to effectuate a two degrees of freedom (DoF) bending motion. Simplified models of the continuum section based on extensions of previous theories assuming constant curvature are presented. The modeled-predicted kinematics and statics of the continuum section can be readily verified by motion trackingsystem. ; Since the continuum robot is a flexible structure, the accuracy is low when the control of continuum robot is solely based on the kinematics model. To reduce the reliance of the exact model that describes the motion of each part of the continuum robot, this dissertation presents an idea to use the position feedback to relax the reliance on the exact model to achieve an accurate closed-loop control of the continuum robot. The actual bending angle of the continuum robot is captured by the optical tracking system. The difference between the desired position and ...
