Acoustic Levitation

About the project

We built another levitation machine with 72 ultrasonic transducers. We want to show that robotics and science can be really cool!

Today with an Arduino, a 3D printer and information found online, its possible to make extroardinary machines.

We built a levitation machine that uses 72 ultrasonic transducers. The transducers work at 40 kHz and can trap objects with a density greater than2.2g/cm3 and a diameter of 4mm.

The levitation of water, paper and styrophoamspheres is possible and shown in this video.

Now you can get all the components in this kit:
