Continuum manipulators offer many advantages compared to their rigid-linked counterparts, such as increased degrees of freedom and workspace volume. Inspired by biological systems, such as elephant trunks and octopus tentacles, many continuum manipulators are made of multiple segments that allow large-scale deformations to be distributed throughout the body. Most continuum manipulators currentl...

Robotic automation has been the major driving force in modern industrial developments. High speed pick-and-place operations ...nd their place in many manufacturing applications. The goal of this project is to develop a class of high speed robots that has a planar workspace. The presented robots are intended for pick-and-place applications that have a relatively large workspace. In order to achi...

Human–robot interaction represents a critical factor in the design of personal robots as well as in the implementation of robot behavior and control. This work investigates and proposes solutions to the problem of controlling an anthropomorphic robot arm for personal assistance, by dealing with the peculiarities of its design, i.e. the mechanics of its cable-actuated, intrinsically compliant st...

A cable-driven soft robot with redundancy can perform the tip trajectory tracking task and in meanwhile fulfill some extra constraints, such as a designated orientation, or avoiding obstacles environment. These constraints require proper motion planning of material-based body that be axially compressed. In this letter, we derive compressible curvature kinematics which takes undesirable axial co...

With the development of cities, more high-rise buildings continue to emerge. Regular cleaning building exterior walls is necessary, which mainly relies on manual work now. In this article, planar four-cable-driven parallel robot (CDPR) adopted carry out external buildings. Firstly, kinematic model and static are established. The influence maximum cable force workspace analyzed, position connect...

A planar cable-direct-driven robot (CDDR) architecture is introduced with only translational freedoms. The motivation behind this work is to improve the serious cable interference problem with existing CDDRs and to avoid configurations where negative cable tensions are required to exert general forces on the environment and during dynamic motions. These problems generally arise for rotational C...

Cable-based robots build upon mechanisms that not only use rigid links in their structures but also utilize unilateral force elements such as cables to deliver the desired motion. Cables may be either connected to active winches to provide a variable length and hence to actuate the mechanism or may be only to provide a kinematic constraint to eliminate an undesired motion of the endeffector. Ma...

Cable-Driven Parallel Robots (CDPRs) are a special kind of parallel manipulator that uses cables to control the position and orientation mobile platform or end effector. The use instead rigid links offers some advantages over their conventional counterparts. As can only pull but not push, number (n) required command end-effector is always n+1. This configuration known as fully-constrained, it m...

Ship cleaning is mainly done manually, which high operation risk and low work efficiency. For that, it proposed to apply the cable-driven parallel robot field of ship cleaning. The related research traditional focused on fixed base, largely ignores influence base motion its performance. Considering caused by wave excitation modeling accuracy, dynamic model system established Newton-Euler method...
