  Oh, that makes me sad. I didn’t watch the full video, so I’m not sure how it works and I hope it didn’t hurt the snake.

    I don’t think it hurt the snake exactly. The thing is basically a hardcoded pattern of “walking” played on servo motors (by comparing the current position to where it’s supposed to be then just turning in the general direction), with a switch that makes it freeze in place. When the motors were “frozen”, those would still wiggle around some set point. This made the snake not want to go in.

    What they did is cut power to the motors completely to let the snake slide in, then turned the contraption on with the snake inside.
