IEEE Spectrum has info about a new autonomous lawnmower from the German company Bosch. Seems the only official info available at the moment is a Swedish press release but it appears the mower communicates with its docking station (and maybe GPS) allowing the unit to cut areas in ordered parallel lines rather than the chaotic back and forth paths you see from other sensor based robotic lawnmowers or vacuums. You will still have to install wire around the perimeter so the robot stay on the grass. The battery lasts 20 minutes per charge and resumes where it left of after a 90 minute charge.

The Fluid Mechanics Laboratory and the Swartz Lab at Brown University are in development of a biological inspired bat robot platform that aims to reproduce the amazing maneuverability of these flying mammals. Bats exhibit extraordinary flight capabilities that arise by virtue of a variety of unique mechanical features. These flying mammals have developed powerful muscles that provide the folding and extension of their wing-membrane during flight (morphing). The maneuverability is achieved by reproducing the flapping and morphing capabilities of their wing-skeleton structure. This structure is composed by several joints and a membrane that generates the required lift forces to fly. Each wing has 4 degrees of freedom: the shoulder has two, the elbow joint is actuated by Migamotors SMA-muscles, and the wrist is an under-actuated joint that moves as a function of the elbow. The robot morphology is alike in proportion compared to the biological counterpart (half the size): total wingspan: 50cm, humerus length: 5.5cm, and radius: 7cm. The total weight of the skeleton is 34g (including both wings). The morphing actuation mechanism attached to the humerus bone is based on smart muscles that provide elbow rotation.
