New ‘Soft’ Motor Made From Artificial Muscles

Wednesday, February 15, 2012
Perhaps the earliest public demonstration of an electric motor,” writes a team of researchers from the University of Auckland in New Zealand, “involved the automatic rotation of a turkey on a spit over a fire” at a party put on by Benjamin Franklin in 1749. Franklin’s electrostatic motor was self-commutating, meaning that it was able to provide a continuous torque while it turned without requiring external electronics to control its progress.

Using artificial muscles, hyper-elastic materials that expand when a charge is applied, the New Zealand team has made a prototype for a self-commutating artificial muscle motor that does not require external electronics or hard metal parts. The researchers describe the device in a paper accepted to the American Institute of Physics’ journal Applied Physics Letters.

The team’s proof-of-concept motor is controlled with carbon-based switches whose resistances change when they are compressed, which activates artificial muscles that rotate a shaft. . . . Read Complete Report

Flying Robotic Insects A New Mass-Production Technique For Electromechanical Devices

Wednesday, February 15, 2012

A new technique inspired by elegant pop-up books and origami will soon allow clones of robotic insects to be mass-produced by the sheet.

Devised by engineers at Harvard, the ingenious layering and folding process enables the rapid fabrication of not just microrobots, but a broad range of electromechanical devices.

In prototypes, 18 layers of carbon fiber, Kapton (a plastic film), titanium, brass, ceramic, and adhesive sheets have been laminated together in a complex, laser-cut design. The structure incorporates flexible hinges that allow the three-dimensional product—just 2.4 millimeters tall—to assemble in one movement, like a pop-up book . . . Read complete report
