| Rethinking the robot hand at Harvard (video) Aug 4th 2012, 15:02  Should you ever find yourself needing to discuss the state of the robotic hand in the early 21st century, Harvard professor Robert Howe seems about as good a place to start as any. The professor founded the school's BioRobotics Laboratory in 1990 and has devoted a good deal of his time to the quest for perfect robot extremities. The last few years have seen a number of breakthroughs for Howe and his team including, notably, the SDM (Shape Deposit Manufacturing) hand, an adaptable and rugged robot gripper that utilizes a single motor to manipulate its eight joints. Such machines have, in the past, often relied on precise image sensing to determine the exact size and shape of an object, in order to configure their digits perfectly before attempting to pick it up. The SDM hand is a lot more forgiving. The pulley system at play distributes equal tension to the fingers in an adaptive transmission that allows motion to continue in other fingers, should one's movement be hampered. The joints themselves are extremely compliant as well, adapting and conforming to the shape of an object, thanks in part to their ability to pivot in three dimensions. The Shape Deposit Manufacturing technology used to create the fingers, meanwhile, adds an important level of durability, letting Howe bang them against a table (a trick he happily performed for us) and expose them to water -- both features that are quite often absent in more complex (and far more expensive) models. The SDM technology, developed at Stanford, allows for the creation of fingers that are a single piece, with their parts embedded in plastic. The larger model shown off by Howe serves as great visual when describing the benefits of the single motor system, but the team has also developed a smaller version, with the requisite motors embedded in a far more compact chassis, which we also got a peek at. The hand will likely be targeted at home and office use, with some key applications for assisting the disabled. Check out a video of Howe describing the technology to us during our visit to the school and a clip of the SDM doing its thing in the labs, which should help feed your desire to watch robot hands get banged by hammers.

Cupertino's Scott Forstall, for instance, took the stand on Friday to give some insights on the beginnings of what Apple called "Project Purple," and the secrecy that surrounded the first iPhone's development. "We're starting another project," Forstall would tell potential recruits to the project, "It's so secret I cannot tell you what the project is. You are going to have to give up nights and weekends for a couple years." These were the words that conscripted much of the team that would eventually build Apple's first phone. Forstall said that the engineers he recruited weren't told anything about the project or even who they would report to -- eventually, Apple locked down one of its Cupertino buildings, affectionately calling it the "purple dorm" for its vague pizza-like aroma. When Apple's attorney questioned the senior vice president of iOS software about how the Project Purple team drove innovation, Forstall went on to describe the challenge of building a touch-centric OS. "Everything we dealt with before was based on mouse and keyboard, and here we were changing the entire user interface to be based around touch. We had to rethink everything about what big controls would be knowing where you are in the document, knowing when you reach the list... Every single part of every device had to be rethought for doing touch." Samsung's legal team was more concerned with how Project Purple was inspired by competitor devices; Forstall responded by saying that Apple simply tested Purple's call performance against other devices, noting that "it's fine to benchmark for performance reasons, it's not OK to copy and rip something off." The comments are interesting, but they probably won't weight too heavily on the jury's final decision. Still, the stories are entertaining, and worth a read for those interested in the iPhone's origins. Even so, we'll be glad when the patent wars are finally over. Filed under: Cellphones, Misc.
