Outer-rotor-type Spherical Ultrasonic Motor : DigInfo

Tokyo University of Agriculture and Technology has developed an outer rotor spherical ultrasonic motor featuring unprecedented compactness and rotational freedom. This new spherical ultrasonic motor boasts a spherical diameter of just 20mm.
The new compact motor features a multi-degree of freedom that enables it to rotate around in the direction of x, y, and z-axes. Consequently, the motor is capable of free spherical movement. The range of movement is 300 degrees around the X-axis; 300 degrees around the Y-axis; and 360 degrees around the Z-axis. The new motor features a rotational speed of 40rpm. It is possible to mount a camera on top of the motor thereby providing the camera with a multi-degree freedom of movement. This new motor offers numerous advantages including compactness, multi-degree freedom of movement, and a wide range of movement. it will undoubtedly be suitable for a variety of applications. Tokyo University of Agriculture and Technology has been in the process of developing a small pipe inspection robot designed to inspect the interior of small diameter piping for damage. The University's newly developed spherical ultrasonic motor would be ideal for use as the inspection robot's camera actuator as well as for the robot's eyeballs and joints.

@Daemo4 just like in the movie i-robot

[blqkvo]

clever!

@openuniverse2003

Err... I've accidentally touched an ultra sonic motor and it felt like I got electrocuted. Not very good for that industry :P

[openuniverse2003]

Adoption by the porn industry would guarantee this thing getting mass produced like crazy!

[Imot744]

thats a very good question...

[brandon9271]

I would say yes.. and that would be sweet!

[Daemo4]

Sooo, are we going to have spherical car wheels now? If you were to mount the motor assembly to a stationary object, could the ball spin freely in any direction?

amazing
