SpringsOptimization•Springs are added between the end-effector and a base to modulate the workspace of Cable-Driven Parallel Robots (CDPRs).•Effects of different parameters of the spring on CDPR's wrenches
was capable of reducing wire forces generated by the active components for a given task. A first discussion of optimizing the springs not only for a workspace, but for a defined trajectory was presented in [31]. Gao et al. proposed a cable-driven flexible parallel robot ...
a frame for receiving a portion of each of said individual fluid conduits, each of said individual fluid conduits being in a spaced-apart parallel relationship with one another in said portion in said frame; multiple occluder arms pivotably mounted in said frame, each of said arms being pivot...
Attached between the plate 49 and the arms 47, 47a are coil tension springs 50, 50a, respectively, normally urging said arms in a counterclockwise direction. The pulsing units 55 Rotatably received, in a pair of horizontally aligned holes in side plates 15, 17, is a transverse shaft 51 ...

SpringsOptimizationCable-driven parallel robots (CDPRs) possess a number of promising advantages over conventional rigid-link robots, such as light weight, large payload handling capacity, considerably large workspace, and simpler dynamics. However, since cables can only pull but not push its ...
7. The slides 111 are longitudinally slidable on supporting bars 125, are spaced by combs 127, and are urged forwardly (to the left in Fig. 7) by springs 129. During a normal adding cycle the forward movement of each of the slides 111 is differentially controlled by " set up " ...
The plate 143 and the leg 142 are formed, as best shown in Figures 1 and 7, to support a cross-rod 145 to which ends a series of hammer-springs 146 may be attached, the other ends of said springs being attached to the auxiliary hammers 118, as indicated in Figures 1, 4 and 7. ...
As is shown in Figs. 1 and 2, the bifurcated lower ends of the key stems I I of the keys 110 each embrace a stud 120 on a pivoted arm 121, there being an arm 121 associated with each key 10. The arms 121 are urged upwardly against a stop rod 455 by individual springs 466 set...
A method for transferring fluids from multiple source containers to a single receiving container wherein fluid is transferred from a source container to a transfer chamber under the influence of a differential pressure and under the control of an occlusion force between the source container and the ...
