Development of a spherical stepper wrist motor

Journal of Intelligent and Robotic Systems: Theory and Applications, 1988
The design concept is presented of a novel spherical stepper robotic wrist motor capable of three-degree-of-freedom (DOF) motion in a single joint for applications where high-speed manipulation of end-effector orientation is required continuously in all directions. Typical applications are plasma and laser cutting and microassembly. The spherical motor

Design and implementation of spherical ultrasonic motor

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2009
We present a mechanical design and implementation of spherical ultrasonic motor (SUSM) that is an actuator with multiple rotational degrees of freedom (multi-DOF). The motor is constructed of 3 annular stators and a spherical rotor and is much smaller and simpler than conventional multi-DOF mechanisms such as gimbals using servomotors.

Control and design of the spherical pointing motor

[1993] Proceedings IEEE International Conference on Robotics and Automation, 2002
A miniature pan-tilt actuator, the spherical pointing motor (SPM) has been built. The SPM is an absolute positioning device, designed to orient a small camera sensor in two degrees-of-rotational-freedom. It is 4 cm*5 cm*6 cm and weighs 160 g. The operating principle of the SPM is to orient a permanent magnet to the magnetic field induced by three ...

Rapid Fabrication of Bimetallic Spherical Motors

Langmuir, 2010
Catalytic bimetallic nanomotors can swim at 100 body lengths per second as well as pick up, haul, and release micrometer-scale cargo. The electrokinetic locomotion of bimetallic nanomotors is driven by the electrocatalytic decomposition of hydrogen peroxide.

On the Controlling of Spherical Ultrasonic Motor

Applied Mechanics and Materials, 2013
Research team of Prof. Shigeki TOYAMA has developed at Tokyo University of A&T a new type of ultrasonic motor. Its spherical shape confer 2 or 3 degree of freedom in a single joint which makes it suitable for mechatronics field. In order to control the Spherical Ultrasonic Motor a new method by using Hall sensors and a residual magnetic field ...
