A research project will be conducted this week in Linz, Austria, to discover what the ideal interaction between people and humanoid robots ought to be in the future, Honda R&D and Ars Electronica Futurelab announced today. The research, the first of its kind in Europe, will involve members of the public directly interacting with ASIMO, Honda's humanoid robot.

Honda and the Ars Electronica Futurelab are collaborating on a human-robot interaction study this week in Linz, Austria (September 2nd ~ 8th).  Although they say their goal is to determine how robots ought to interact with people in the future, I think this may be just an excuse to let the public have some one-on-one fun with ASIMO.  In any case, these sorts of studies should help steer Honda’s engineers in the right direction when designing the next version of the world’s most famous humanoid robot.

Bipedal humanoid robots can step over obstacles and negotiate stairs where their wheeled counterparts cannot, but this comes with the risk of falling down.  Naturally, humanoid robots will never be accepted in society if they break when they fall down.  The bigger the robot, the more likely it is that it will damage itself during a fall and be unable to get up. In 2003 the HRP-2P was the first full-scale humanoid that could fall over safely and get back up, and so far remains alone; not even Honda’s ASIMO can do this.  As soon as it detected that it was falling, the HRP-2P would bend its knees and back, which helped to reduce the ground impact.  This motion, called “UKEMI”, is quite similar to how the SONY QRIO would react when falling over to reduce the risk of damaging its components.

Dennis Hong, a professor of mechanical engineering and director of Virginia Tech's Robotics & Mechanisms Laboratory, or RoMeLa, has created robots with the most unusual shapes and sizes -- from strange multi-legged robots to amoeba-like robots with no legs at all. Now he's unveiling a new robot with a more conventional shape: a full-sized humanoid robot called CHARLI, or Cognitive Humanoid Autonomous Robot with Learning Intelligence. The robot is 5-foot tall (1.52 meter), untethered and autonomous, capable of walking and gesturing. But its biggest innovation is that it does not use rotational joints. Most humanoid robots -- Asimo, Hubo, Mahru -- use DC motors to rotate various joints (typically at the waist, hips, knees, and ankles). The approach makes sense and, in fact, today's humanoids can walk, run, and climb stairs. However, this approach doesn't correspond to how our own bodies work, with our muscles contracting and relaxing to rotate our various joints.
