Video of the experiment shows tubular robots that move by extending their shafts to inch along the ground. As the tubes gather, they connect and form into more complex shapes like triangles and tetrahedrons. With each piece consumed, the whole moves faster and with more elegance. "AI systems need bodies to move beyond current limitations. Physical embodiment brings the AI into the messy, constraint-rich real world -- and that's where true generalization has to happen," Phillipe Martin Wyder, lead researcher on the project, told 404 Media.Read more of this story at Slashdot.
