“…A cable driven parallel manipulator, according to its number of cables (m) and degrees of freedom (DOFs) of end-effector (n), can be classified as follows (Verhoeven et al, 1998;Hiller & Fang, 2005) fixed end of the cable; E the elastic modulus; A 0 the unstrained cross-sectional area. Using the variables and coordinate system above, we will briefly reproduce Irvine's derivation in this paper (Irivne, 1981).…”

“…The authors of [8] describe generation of time-minimal trajectories for six degree-of-freedom parallel configurations, whereas [9] describes trajectory generation for cable based parallel manipulators. Much of this prior work aims to minimize time of execution of a desired trajectory, which often adversely affects energy efficiency.…”
Abstract-In this paper we describe an algorithm to generate energy efficient trajectories for NIMS3D, a three-dimensional cabled robotic platform. Optimized parabolic paths are used to exploit the relatively low I 2 R loss associated with operation in lower regions of the workspace. Trajectory optimization is sufficiently fast to enable real time operation. Experimental results on a physical system for a three cable deployment show substantial reductions in energy consumption as compared to linear trajectories.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
