The Robogymnast is a complex system formed from a triple-inverted pendulum and mimics the action of a gymnast as they hang by their hands from a high bar and perform progressive upswings to eventually rotate completely around the bar. The three links of the Robogymnast can be compared to the lower limbs. the torso. and the upper limbs of a gymnast. https://quarterfoures.shop/product-category/shop/
