Dec 02, 2020 · A novel efficient downstairs trajectory is proposed for a 9 link biped robot model with toe-foot. Brachistochrone is the fastest descent trajectory for a particle moving only under the influence of gravity. In most situations, while climbing downstairs, human hip also follow brachistochrone trajectory for a more responsive motion..
The angle of this deviation can be calculated using Snell's law. As one continues to add layers of reducing densities in front of the deviated beam of light, until the beam reaches the critical angle, where the beam simply gets reflected, the trajectory of the beam describes the brachistochrone curve. (the red curve in the diagram above).

This curve is subject only to the gravitational force in which friction does not act. A cycloid is only an approximation of the optimal trajectory if there are forces other than gravity and the support reaction. The Brachistochrone theory was experimentally demonstrated with three types of curves and three types of objects.
A great number of analysis and synthesis problems of modern processes can be written as state and control constrained optimal control problems governed by ordinary differential equations with multipoint boundary values. As the software tools for following this attractive approach are still missing or can be used only by experts, the structure and usage of an easy-to-use software package is.
To do this, proceed as follows: Mark a point on the circumference of a hoop, lid, or other circular object, whose radius you have measured. The height of your brachistocrone ramp is going to be diameter of the circumference you will use.
