Adaptive Dynamic Programming-Based Fault-Tolerant Position-Force Control of Constrained Reconfigurable Manipulators [PDF]
IEEE Access, 2020 This article presents a novel fault-tolerant position-force optimal control method for constrained reconfigurable manipulators with uncertain actuator failures. On the basis of the radial basis function neural network (RBFNN)-estimated manipulators dynamics, the proposed force-position error fusion function and the estimated actuator failure are ...

A Hybrid System Approach for Cooperative Control of Mobile Manipulators
, 2007 本論文提出一個應用於兩台移動式機器手臂合作搬運的分散式控制法則，且同時考量搬運過程之穩定性與操控性。我們首先將軌跡規劃的指令下達給其中一台移動式機器手臂，稱之為領導者，而另外一台移動式機器手臂稱之為追隨者，此機器人須協調其軌跡並保持抓取物體的狀態。接著，我們利用順應運動控制於兩台機器手臂來補償兩個移動式平台的位置誤差，同時保持預期的內力。除此之外，當環境中有障礙物時，我們運用混成式系統的方法來建立合作的模型以完成任務。混成式系統結合了離散事件與連續的動態行為，且將決策的邏輯 ...

Dynamically Reconfigurable Tactile Sensor for Robotic Manipulation
IEEE Robotics and Automation Letters, 2020We present a tactile sensor intended for manipulation by mobile robots, e.g., in the home. The surface consists of an array of small, rounded bumps or “nibs,” for reliable traction on objects like wet dishes. When the nibs contact a surface they deflect, and capacitive sensors measure the corresponding local normal and shear stresses.
