The holiday season brings two questions: "Isn't it time to put up the Christmas lights?" and "When do we take down the Christmas lights?" Edward Nauman designed retractable icicle lights that go up or down with a flick of a switch. He used rotating lengths of metal conduit to wrap up lights and keep them out of sight behind a facia board. Ed's invention brought peace to his holiday season. The design involves a bracket, a motor, micro-switches, conduit and a few other odds and ends, plus some metalworking experience.
Unlike industrial robots, which suffered a slight overall slump in 2012, service robots continue to be increasingly in demand. The majority are used for defense, such as unmanned aerial vehicles (UAVs); and agriculture, such as milking robots.
Festo's BionicKangaroo combines pneumatic and electrical drive technology, plus very precise controls and condition monitoring. Like a real kangaroo, the BionicKangaroo robot harvests the kinetic energy of each takeoff and immediately uses it to power the next jump.
