Special Issue Information

Dear Colleagues,

With the increasing demand of industrial automation and robots around the world for a multi-degree-of-freedom (DOF) motion mechanism, a motion mode for actuators has been developed from simple 1-DOF motion to a multi-DOF motion and application of humanoid is actively proceeding. Conventionally, for joints and eyeballs of the humanoid, the multi-DOF systems are implemented with multiple motors to mimic the movement of human body. Multi-DOF systems are devices that can set orientation and positioning of the object in any direction. However, these systems have increasing weight and size. In recent years, various multi-DOF actuators have been developed and designed to achieve the multi-axis or multi-DOF motion.

Along with recent advances in materials sciences, stretchable electronics, and mechatronics, the research and development of multi-DOF actuators is rapidly increasing. The reasons lie in their multifunctionality, low cost, fast response, high repeatability, and small size, making them a promising solution for the industrial automation and robots. Applications of multi-DOF actuators cover a wide range of fields such as robotics, joints and eyeballs of the humanoid, haptic device for an augmented reality system, camera modules, data storage devices, projectors, optics, optoelectronics, and medical and mechanical engineering, to name a few, which are expected to expand substantially in the years and decades ahead.

Multi-DOF motion is realized in the eyes and joints of robots mostly through the combination of multiple one-degree-of-freedom (1-DOF) motors. However, this results in reduced efficiency, a large volume, reduced response speed, and inaccurate positioning. To solve these problems, this study proposes a novel 3-DOF spherical voice coil motor (VCM). In this VCM, 16 coils and a radially oriented ring magnet are used to generate a Lorentz force to achieve motion. In particular, coils for Z-axis rotation are sandwiched between the coils for X- and Y-axis rotation. Furthermore, the proposed VCM can achieve 360° rotation about the Z-axis. The commercial software ANSYS was used to design and verify the performance of the proposed VCM. Simulation results indicate that this VCM affords improved power efficiency because only a suitable combination of coils, rather than all coils, needs to be powered on. The results demonstrate the feasibility of the proposed 3-DOF spherical VCM. Full article

Abstract: The robotic arm is mostly a combination of multiple 1-degree-of-freedom (1-DOF) motors to meet its multi-DOF motion, but this will result in a large volume, reduced efficiency, and even decrease the speed of response and inaccurate positioning. Therefore, this article proposes a new type of 3-DOF spherical voice coil motor (VCM) with high power efficiency to solve this issue. In the structural design, 16 coils and a radially oriented ring magnet are used to generate the Lorentz force as a power source. Specially, the coils for Z-axis rotation are sandwiched between the coils for X-axis and Y-axis rotations. In addition, due to the specific design of the proposed structure, the proposed 3-DOF spherical VCM can reach 360 degree-rotation along Z-axis. In this article, a commercial software, ANSYS, was used to design and verify the performance of the proposed 3-DOF spherical VCM. From the simulation results, the power efficiency of the proposed 3-DOF spherical VCM can be improved by powering on the suitable coil combination. It demonstrates the feasibility of the proposed 3-DOF spherical VCM.
