This past spring, Sam Altman, the 38-year-old CEO of OpenAI, sat down with Silicon Valley’s favorite Buddhist monk, Jack Kornfield. This was at Wisdom 2.0, a low-stakes event at San Francisco’s Yerba Buena Center for the Arts, a forum dedicated to merging wisdom and “the great technologies of our age.” The two men occupied huge white upholstered chairs on a dark mandala-backed stage. Even the moderator seemed confused by Altman’s presence.

“What brought you here?” he asked.

The Tetraflex, a tetrahedron-shaped robot equipped with flexible piping, is capable of navigating the most challenging terrains and transporting delicate cargo, opening up a world of possibilities for applications ranging from disaster response to ecological surveying.

Researchers at Cornell University have developed a tiny, proof of concept robot that moves its four limbs by rapidly igniting a combination of methane and oxygen inside flexible joints.

The device can’t do much more than blow each limb outward with a varying amount of force, but that’s enough to be able to steer and move the little unit. It has enough power to make some very impressive jumps. The ability to navigate even with such limited actuators is reminiscent of hopped-up bristebots.

Electronic control of combustions in the joints allows for up to 100 explosions per second, which is enough force to do useful work. The prototype is only 29 millimeters long and weighs only 1.6 grams, but it can jump up to 56 centimeters and move at almost 17 centimeters per second.
