Researchers have innovated a new 3D-printed that moves by harnessing the vibrations from Piezoelectric Actuators, Ultrasound sources.
Tiny speakers can be used to move artificial ants because they act through vibrations.
- Swarms of these may be used for a lot things including but not limited to sensing environmental changes, move materials. These may even be used to perform surgery inside the human body.
- Different prototypes respond differently to every frequency. This allows the researchers at Atlanta to control individual bots by simply adjusting the frequency of vibration.
- These robots are designed after the tiniest ants in the world. They are about 2 MM in length and weigh about 5 mg.
- The technology is not robust enough yet. Although there are multidisciplinary concept designs and possible applications for this robot, it needs more research and development to overcome its physical limitations.
- “We are working to make the technology robust, and we have a lot of potential applications in mind,” said Azadeh Ansari, an assistant professor in the School of Electrical and Computer Engineering at the Georgia Institute of Technology.
- The micro-bristle bots are powered externally because they are too tiny to fit even the smallest of batteries that exist.
- A paper about the micro-bristle-bots will soon be published in the Journal of Micromechanics and Microengineering.
- How it works: The vibrations move the springy legs of the bots up and down responding to respective vibrations. This response is dependent upon leg size, geometry and design and the diameter of legs.
