I suspect it's still alive after all that.
edit:
@SomeGuy1 Sure it is, you just have to apply a force through the leg that counteracts any rotation induced by gravity (aka falling while keeping the leg straight). Meaning all it needs is something akin to a wheel-axis in the knee-joint that tries to spin the leg in opposite dir. Sort of like how unicycling works, except the wheel is stuck (on the ground), so only the top half can move.
