    A fly-brain model reportedly surfed for 41 seconds in a simulation

    The post describes 166,700 traced cells and 25.56 million synapses processing visual and board-tilt inputs to make balance corrections 26 times a second.

    TLDR

    A post claims a modeled fly nervous system kept a surfboard upright for 41 seconds on run 263, after 262 attempts ended in the water. It describes feeding a rendered wave into the system’s visual pathways and board-tilt signals through nerves used for balance in flight. According to the account, feedback consisted of dopamine tied to time upright, with no demonstrations or example rides. The post also notes the setup’s limits: simplified water and a rigid board.

    @Roxx_0xA DEAD FLY'S BRAIN WIPED OUT 262 TIMES, THEN SURFED FOR 41 SECONDS Balance is the oldest unsolved problem in robotics. Humanoids that cost millions still fall over. -> This one had the loop already in it. The rider is male CNS v1.0: 166,700 traced cells and 25.56 million synapses, run as measured. A moving wave face was rendered and projected onto 759 ommatidia, the channel the insect sees with. Board tilt went in through the haltere nerves, the gyroscope a fly uses to stay level in flight. The central complex held a heading. Thirty-four output lines drove the correction into the legs. Corrections landed 26 times a second and kept the board inside four degrees of upright. Run 263 stayed up for 41 seconds. The 262 before it ended in the water. Feedback was dopamine on time upright, nothing else. No demonstrations, no example rides. The limits are real: the water is simplified, the board is rigid, and a fly has never once been near a wave. Nothing was taught here. A flight stabiliser that evolved over 250 million years was pointed at a different problem. The wiring for standing on moving water was already inside an insect ↓
