Robot Unravels the Mystery of Walking 134
manchineel writes with a link to a BBC article on the lessons learned from a project in locomotive robotics. 'Runbot', as it is known, is the result of a modern technology combined with a 1930s physiology study into human locomotion. The study found that walking is largely an automatic process; we only engage our brains when we have to navigate around an obstacle or deal with rough terrain. "The basic walking steps of Runbot, which has been built by scientists co-operating across Europe, are controlled by reflex information received by peripheral sensors on the joints and feet of the robot, as well as an accelerometer which monitors the pitch of the machine. These sensors pass data on to local neural loops - the equivalent of local circuits - which analyse the information and make adjustments to the gait of the robot in real time."

Also, here's the cited paper. [plosjournals.org]
This isn't that novel. It's very much like Randall Beer's insect work [iu.edu] from a decade ago. It's hierarchical control using controllers built from control blocks the authors call "neurons". It's a pure reflex system, with no explicit prediction.
Also notice that it's a planar biped, constrained so that it can't fall sideways.
There's better locomotion and balance work going on in Japanese hobbyist robotics.
It's good that people are working on this stuff again. There was some impressive work in the 1980s and early 1990s, then a big lull.
