The development of a novel 3D-printed three-claw robotic gripper shall be described in this paper with the goal of incorporating various design considerations. Such considerations include the grip reliability and stability, grip force maximization, wide object grasping capability. Modularization of its components is another consideration that allows its parts to be easily machined and reusable. The design was realized by 3D printing using a combination of tough polylactic acid (PLA) material and thermoplastic polyurethane (TPU) material. In practice, additional tolerances were also considered for 3D printing of materials to compensate for possible expansion or shrinkage of the materials used to achieve the required functionality. The aim of the study is to explore the design and eventually deploy the three-claw robotic gripper to an actual robotic arm once its metal work fabrication is finished.

Materials Used

The physical properties of the materials used are also important in the thermal conduction, besides many other factors. In this study, nettle fiber/polyester composites were formed using stinging nettle grown in the Black Sea region. The stinging nettle fibers used in the formation of these composites were divided into three parts as bottom, middle, and top. The physical properties (diameter, density, crystallinity) of the fibers obtained from different parts of the plant and how the increased fiber concentration affected the thermal conductivity coefficients of the composite materials formed were studied. As a result, it was observed that the thermal conductivity coefficients of the composites increased with the increase of the crystallinity ratio of the fiber. Moreover, the increased fiber concentration significantly increased the thermal conductivity coefficient of the composite materials produced.

Physical And Mechanical Characteristics

The article presents thermoplastic characteristics of polymer composite materials developed on domestic raw materials on a thermoplastic matrix-injection material of the VTP-7 brand based on polyaryl sulfones (polysulfone PSU) plastic and sheet material of the VKU-44 brand based on PSU and carbon unidirectional tape ELUR 0.08 PA. In the article, the author considered the modification method of thermoplastic polymers to impart functional properties and mechanisms of their action. It is shown that the developed materials have no analogues in the domestic industry. According to the level of physical and mechanical characteristics, fire-hazard properties and heat resistance, the developed polymer composite materials (PCM) fully meets the requirements for modern thermoplastic PCM, and is not inferior to foreign analogues.
