Disney Research Develops Hybrid Fluid Transmission
Engineers routinely face tradeoffs as they design robotic limbs – weight vs. speed, ease of control vs. fluidity. A new hybrid fluid transmission developed at Disney Research Pittsburgh promises to eliminate some of those tradeoffs, making possible robot arms that are light enough to move swiftly and gracefully, yet with precise control.
The transmission consists of antagonist pairs of rolling diaphragm cylinders – similar to traditional hydraulic cylinders, but sealed with a rubber diaphragm instead of sliding seals and valves. The result is a system that can efficiently transmit power with little friction. Yet it is also “backdriveable,” capable of absorbing energy, as well as transmitting it.
