Answer:
A Gömböc, that comes back to its upright position no matter how you place it (on a flat surface). A turtle’s shell is shaped up like a Gömböc (not all turtles), which helps it get back on feet when it is flipped over!

    A self-righting shape called the Gömböc. The shell of the Indian star tortoise is also self-righting.

    The shape of the Indian Star Tortoise resembles a Gömböc.


  3. Gömböc.
    From Wiki: The shape of the Indian Star Tortoise resembles a Gömböc. This turtle rolls easily without relying much on its limbs.

    The Indian Start Tortoise is similar to the Gomboc, which is a self-balancing thingy, and always comes back to rest in the same position.

    The shape of the Indian Star Tortoise resembles Gömböc, a convex three-dimensional homogeneous body which, when resting on a flat surface, has just one stable and one unstable point of equilibrium.

    This turtle rolls easily without relying much on its limbs.

    Gomboc has just one stable and one unstable point of equilibrium. Indian Star Tortoise . Its shape resembles a Gömböc. This turtle rolls easily without relying much on its limbs.Their ability to turn back when placed upside down resembles the Gomboc


  7. Gomboc
    the indian star tortoise inspired the shape of the gomboc
    which has 2 stable & 1 unstable point

    It’s a mono-monostatic Gömböc.
    Some turtles exhibit the ability to self-right or “weeble” through evolution.

    I love the inventor’s challenge to find a polyhedral variant. Offering 10,000 dollars divided by the number of sides of the object.

    Gomboc. The Indian Star Tortoise’s shell resembles a Gomboc. This explains how it can quickly overturn when placed upside down.

    A Gömböc, is a convex three-dimensional homogeneous body which, when resting on a flat surface, has just one stable and one unstable point of equilibrium. Turtle shells apparently have the same structure which help them in returning to their equilibrium position when placed upside down.

    The white object is self-righting; it only has one stable and one unstable balance point, so in practice, it can always right itself, like a turtle (or at least a turtle with a little effort). (Object by Domokos and Várkonyi.)

    Gomboc..
    The balancing properties of the Gömböc are associated with the “righting response”, their ability to turn back when placed upside down, of shelled animals such as turtles and beetles.

    It’s a coconut!

    it’s used to model a tortoise and the ability of a tortoise to self-right itself based on the shape of its shell.

    Gomboc – a 3D object with just one stable and one unstable equilibrium point. Conjectured to exist by Vladimir Arnold and constructed by Domokos and Varkonyi. They used this theory to explain the self-righting mechanism of turtles such as the Indian star tortoise. Their shells are shaped like a Gomboc and so they can turn over without much help from their limbs. Awesome question.

    Coconut shell (tortoise)

    Gomboc and Indian Star tortoise.
    The shape of the tortoise, which resembles the gomboc, allows it to roll and get up when it is placed upside down.

    Gomboc!!
