 Notice the weight body is dynamic so it will be affected by gravity. The physics will be pushing down on the weight, but the speed movements of the insect will compensate and create more randomness to the movement. The revolute joint will keep the weighted object at the bottom, eventually straightening the insect if it is upside down.  Notice the weight body is dynamic so it will be affected by gravity.
