Nao humanoid climbs spiral staircase, breakfast in bed is around the corner (video)
Robots can clean your pool and pick up after your lavish dinner parties, but what use is Mr. Nao when you're ringing for a nightcap from the comfort of your second-floor bedroom? Okay, so we've seen the odd bot take a journey up some stairs, but how many cyborgs are prepared to scale flights that twist and turn? Researchers from the University of Freiburg's Humanoid Robots Laboratory have demonstrated a Nao humanoid capable of climbing spiral staircases, which, of course, are more challenging to scale than their non-curving counterparts. A laser range scanner on the top of the robot's head provides a global estimation of the bot's position, and the humanoid uses a 3D model of the staircase to match up with the images it captures on each step. This system lets it get a good enough grip on its geography to successfully detect stair edges and make it to the top with nary a trip. Take a look for yourself in the video below.
iRobot engineer builds stair-climbing robot for Masters thesis, not release
What does an iRobot engineer do for their Masters thesis? Build a robot, of course -- and, in the case of this one particular unnamed engineer, a stair-climbing robot. Unfortunately, any other details are a bit hard to come by, but it looks like the folks at iRobot were impressed enough with the bot to throw a short video of it up on the company's official YouTube channel. As you can see for yourself after the break, while it is a bit on the pokey side, it certainly seems to be more than capable of performing the task at hand with ease, and with some satisfactory buzzing and whirring sounds to boot.
