The Honeybee Rotary Band Contact features long-wearing beryllium copper contact bands.
An alternative to conventional slip rings, the Honeybee Rotary Band Contact (RBC) features a contact design that targets service life and electrical noise. Rather than brush contacts, the RBC makes use of flexible bands of gold-plated beryllium copper.
Axially retained by a lip on the planet assembly's Vespel polyimide spacers, these "flex-band" contacts are designed to maximize the rolling contact with the RBC's stationary ring bands, thus minimizing wear. And the consistent nature of the rolling contact also keeps electrical noise at bay: Honeybee estimates the noise levels at roughly an order of magnitude less than a comparable brush contact.
On the downside, the flex band contacts cost more than brushes and have an aversion to dust and other contaminants, requiring seals for the contact area. The RBC's layout and number of planet assemblies varies according to current-carrying needs and packaging constraints.

Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
