Performing aerial 6-dimensional manipulation using flying robots is a challenging problem, to which only little work has been devoted. This paper proposes a motion planning approach for the reliable 6-dimensional quasi-static manipulation with an aerial towed-cable system. The novelty of this approach lies in the use of a cost-based motion-planning algorithm together with some results deriving ...

The tendon driven mechanism using a cable and pulley to transmit power is adopted by many surgical robots. However, backlash hysteresis objectively exists in cable-pulley mechanisms, and this nonlinear problem is a great challenge in precise position control during the surgical procedure. Previous studies mainly focused on the transmission characteristics of the cable-driven system and construc...

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...

We present the simulated dynamics and control of a planar, translational cable-direct-driven robot (CDDR). 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 and moments on the environment and during dynamic motions. Generally for CDDRs the command...

Cable array robots are a class of robotic mechanisms which utilize multiple actuated cables to manipulate objects. This paper discusses the defining characteristics and the important issues relating to this class of robots. One particular type of cable array robot with three cables is presented in detail including kinematic relations and dynamic modeling. The resulting models are used to design...

Cable-driven parallel robots can have a much larger workspace than other with rigid links or conventional serial robots. This property comes at the cost of more complex calculations and control schemes that are necessary to account for elasticity unilateral force transmission their cable links. In practice, most cable-driven cannot achieve full is predicted by theoretical models. due calibratio...

This paper proposes the use of a randomized kinodynamic planning technique to synthesize dynamic motions for cable-suspended parallel robots. Given two mechanical states of the robot, both with a prescribed position and velocity, the method attempts to connect them by a collision-free trajectory that respects the joint and force limits of the actuators, keeps the cables in tension, and takes th...

In this paper, the kinematics and dynamics modeling of the mechatronic model for a 6 DOF cabledriven parallel robot are covered and a real-time capable simulation model for such robots is derived. The governing equations of motion of the mobile platform are acquired using Newton-Euler formalism, furthermore, the pulley kinematics of the winches and a spring-damper based cable model are introduc...

Cable wound electric machines are used mainly for high voltage and direct-drive applications. They can be found in areas such as wind power, hydropower, wave power and high-voltage motors. Compared to conventional winding techniques, cable winding includes fewer manufacturing steps and is therefore likely to be better suited for automated production. Automation of the cable winding production s...

The separation of gangues from coals with robots is an effective and practicable means. Therefore, a cable-suspended gangue-sorting robot (CSGSR) end-grab was developed in our early work. Due to the unidirectional characteristic, flexibility cables, dynamic impact pick-and-place gangues, one significant issues robustness under internal external disturbances. Cable tensions, being end-grab’s con...
