Abstract
A joystick set for controlling different degrees of freedom was designed, materialized and characterized. The joystick was designed for 3D printing, improved through several iterations, producing multiple samples using multi-material additive manufacturing. Two different materials (one structural and another conductive) were used in the filament material extrusion process to obtain resistive-based sensing unit elements. The sensor was put into operation via a voltage divider circuit. Experimentation was implemented in a testing bed (analogic sensor), in a real context (binary mode) and in a simulation environment (multiple-state signal) for the command of a robotized wheelchair. The final design is capable to meet the requirements of reducing the material used and the printing times. The results reveal the possibility of using 3D printed resistive-based sensing units to implement binary signals as well as multiple state signals and the sensor set has been evaluated by controlling a robotized wheelchair.
我们设计了一套用于控制不同自由度的操纵杆，并对其进行了材料化和特征描述。该操纵杆设计用于三维打印，经过多次迭代改进，利用多材料增材制造技术生产出多个样品。在长丝材料挤压过程中使用了两种不同的材料（一种是结构性材料，另一种是导电材料），以获得基于电阻的传感单元元件。传感器通过分压电路投入运行。实验在测试平台（模拟传感器）、真实环境（二进制模式）和模拟环境（多状态信号）中进行，用于指挥机器人轮椅。最终设计能够满足减少所用材料和打印时间的要求。研究结果表明，使用基于电阻的 3D 打印传感单元可以实现二进制信号和多状态信号，并通过控制机器人轮椅对传感器组进行了评估。
期刊介绍：
The aim of the Journal of Mechanical Science and Technology is to provide an international forum for the publication and dissemination of original work that contributes to the understanding of the main and related disciplines of mechanical engineering, either empirical or theoretical. The Journal covers the whole spectrum of mechanical engineering, which includes, but is not limited to, Materials and Design Engineering, Production Engineering and Fusion Technology, Dynamics, Vibration and Control, Thermal Engineering and Fluids Engineering.
Manuscripts may fall into several categories including full articles, solicited reviews or commentary, and unsolicited reviews or commentary related to the core of mechanical engineering.
