Pneumatic Rotary Vane Joints Lend A Gentle Helping Hand

Festo has released a video showing the workings of their BionicCobot, a pneumatic robot arm developed for lending a helping hand to humans at a workstation. Since it works intimately with humans, it has to be safe, producing no harmful movements, and reacting when encountering an obstacle such as an arm containing delicate human bone. This it does using pneumatics and rotary vanes.

The arm has seven degrees of freedom, three in the shoulder, one in the elbow, another in the lower arm, and two in the wrist. But you won’t find any electric motor or gears. Instead each contains …read more http://pje.fyi/P4BWBy

Flying manta ray blimp

German engineering firm Festo has created this flying manta ray. Dubbed the Air_ray, it’s a balloon made of an aluminum-vaporised “PET foil”. Inflated with helium, the Air_ray’s propulsion system is a flapping wing drive. Each wing has alternating pressure and tension flanks that are attached to an internal set of ribs. The flanks are connected to a remotely controlled servo motor. When pressure is applied to either of the flanks, the wing bends in the opposite direction. By alternating pressure on the flanks, the wings beat. The servos are powered by two 8V LiPo accumulator cells.

The total weight of …read more http://pje.fyi/Nfxzrf
