Pioneered by scientists at Los Alamos National Laboratory, BEAM robots are not programmed to walk; instead they use brainlike circuits called neural networks to learn to walk through trial and error.
BEAM robots are not programmed to walk; instead they use brainlike circuits called neural networks to learn to walk through trial and error
BEAM robots learn to walk through trial and error by using brainlike circuits called neural networks instead of by programming them
BEAM robots are not being programmed to walk but instead using brainlike circuits called neural networks and learning to walk through trial and error
brainlike circuits called neural networks are used instead of programming for BEAM robots learning to walk through trial and error
brainlike circuits called neural networks are being used for BEAM robots that learn to walk through trial and error instead of being programmed
