This work addresses a novel design of a cable-driven parallel robot cube structure. The primary purpose of developing the new robotic structure, as described in this paper, was to integrate the capabilities and skills of 3D printer innovative technology by cable-driven robots and provide high-precision manufacturing by 3D printing capabilities for artistic work of different sizes. The proposed design is intended to operate in a three-dimensional workspace, with the possibility of incorporating more degrees of freedom depending on the specific application requirements. The Cube CDPR structure consists of a mobile platform that has the capability of moving dynamically along the vertical (Z-axis) with sliding movement. This configuration provides increased structural flexibility relative to the rigid and stable platforms typically employed in cable-driven parallel robot architectures. The Cube CDPR structure incorporates four independent motors positioned at the corner edges of the platform. Each motor drives a cable through a pulley system, and coordinated control of cable unwinding and rewinding enables precise regulation of the end-effector position and orientation. The four cables are actuated by stepper motors on the mobile platform, while a fifth control motor adjusts the base position along the Z-axis through vertical sliding motion. This integrated control strategy enables simultaneous control of the platform configuration and end-effector position. Smooth and stable motion is achieved through controlled motor actuation. The cable-driven architecture helps to minimize the mass in motion, while dexterity and resolution of the movements are maximized, which is a requirement for drawing and complex 3D printing. The proposed Cube structure and mechanical configuration are simulated and validated. The characteristics mentioned above show the potential of the proposed system in the fields of artistic robotics and 3D printing.
