Jesse Sullivan, a Tennessee power company lineman whose arms were amputated after he was electrocuted on the job, now has artificial limbs that let him rotate his wrists and upper arms, bend his elbow, grip with his hand, and, incredibly, feel. Sullivan's arm employs nerves from the chest muscle. When that muscle contracts, a myoelectric sensor atop his skin detects the contraction and sends it to an amplifier and then to a digital signal processor (DSP) in the Boston Digital Arm. The arm’s DSP interprets the signal and then sends a command to the hand motor, which closes the hand. (Source: Liberating Technologies)
The nerve reinnervation and prosthetic technology from the Rehab Institute of Chicago is incredible to say the least! I looked for a follow-up on it but couldn't find anything. Any word on how it's progressed since then?
Could our view of distant galaxies be obstructed by a lawnmower? That unlikely question is at the heart of a growing debate between the National Radio Astronomy Observatory and a robot manufacturer that seeks to build self-guided lawnmowers.

Commenters doubted the manufacturers, describing them as H-1B visa promoters, corporate crybabies, and clowns. They argued that US manufacturers aren’t willing to train workers, preferring instead to import cheap labor from abroad.
Using wireless chips and accessories, engineers can now extract data from the unlikeliest of places -- pumps, motors, bridges, conveyors, refineries, cooling towers, parking garages, down-hole drills and just about anything else that can benefit from monitoring.
