A Robot's Gentle Touch
Robot arms aren't usually known for being delicate or dainty, they are usually more about precision and speed. However, if robots are to be among us - which is where we seem to be heading, with robot "butlers", nannies and caretakers - they need to be aware that we "meat sacks" bruise easily, and to tread softly around us.
Mashable...a robotic arm developed by a team lead by Charlie Kemp, associate professor at Georgia Institute of Technology, has sensors that cover its entire “arm,” helping it touch other objects gently, while reaching for a specific item. The technique gives robots a more effective and realistic method for dealing with real-world circumstances, where obstacles and clutter are usually an issue.
