“…Using quintic B-spline curves with higher degrees of freedom can better satisfy these constraints and limitations. The shape of the fifth-degree B-spline curve can be flexibly controlled by adjusting the positions and weights of the control points [ 34 ]. This enables the robotic arm to move smoothly and precisely without collisions, reaching the desired positions.…”

“…Hwang et al [26] presented a scheme to suppress unwanted oscillatory motions of the payload of a four-cable-driven CDPR based on a zero-vibration input-shaping scheme, and the advantage of the proposed scheme is that it is possible to generate an oscillation-free trajectory based on a ZV inputshaping scheme, and moreover, a series of computer simulations and experiments to verify the effectiveness of the proposed method were conducted for three-dimensional motions of a CBPR with four cables. A smooth trajectory planning algorithm to enhance the smoothness of the trajectory when used in rehabilitation training was proposed for a cabledriven waist rehabilitation robot by employing an improved quintic non-uniform rational B-splines [27]. As demonstrated in [28], a novel methodology for the identification of the inertial parameters of the end-effector, based on the use of internal-dynamics equations and free-motion excitations, was proposed for the underactuated cable-driven parallel robots, where the optimal free-motion trajectories were investigated to obtain optimal identification results.…”
