摘要

这项工作展示了一种基于镍钛形状记忆合金（SMA）的旋转型关节伺服机构的设计和构造，该机构具有基于电位计传感器和数字电子位置控制的角度位置测量功能。该原型的预期应用是使用小型电荷来模拟人类的运动，受生物启发并由人造肌肉激活，其潜在应用领域将是医疗和仿人机器人。计算机辅助设计（CAD）可以评估和验证建造伺服机构最方便的参数，实验结果验证使我们获得了原型的运动范围±20°和施加在旋转轴上的最大扭矩 1.01 kg-cm。

Design and construction of a servomechanism using a memory alloy linear actuator

This work shows the design and construction of a servomechanism of a rotator-type joint based on NiTi Shape Memory Alloys (SMA) with an angular position measurement based on a potentiometer sensor and digital electronic position control. The expected application of this prototype is for the use of small charges that emulate the movement of the human being, being bio-inspired and activated by artificial muscles, their potential applications they will be in medical and humanoid robotics. Computer Aided Design (CAD) allows evaluating and validating the most convenient parameters for construction of servomechanism, experimental results validate allowed us to obtain the values of the range of motion

\pm 20 °

and a maximum torque of 1.01 kg-cm exerted on the axis of rotation for the prototype.

期刊介绍： HardwareX is an open access journal established to promote free and open source designing, building and customizing of scientific infrastructure (hardware). HardwareX aims to recognize researchers for the time and effort in developing scientific infrastructure while providing end-users with sufficient information to replicate and validate the advances presented. HardwareX is open to input from all scientific, technological and medical disciplines. Scientific infrastructure will be interpreted in the broadest sense. Including hardware modifications to existing infrastructure, sensors and tools that perform measurements and other functions outside of the traditional lab setting (such as wearables, air/water quality sensors, and low cost alternatives to existing tools), and the creation of wholly new tools for either standard or novel laboratory tasks. Authors are encouraged to submit hardware developments that address all aspects of science, not only the final measurement, for example, enhancements in sample preparation and handling, user safety, and quality control. The use of distributed digital manufacturing strategies (e.g. 3-D printing) is encouraged. All designs must be submitted under an open hardware license.
