Continuous Choreographies as Limiting Solutions of $N$-body Type Problems with Weak Interaction [PDF]
We consider the limit $N\to +\infty$ of $N$-body type problems with weak interaction, equal masses and $-\sigma$-homogeneous potential ...

Dynamic modeling of dual-arm cooperating manipulators based on Udwadia–Kalaba equation
Dual-arm cooperating manipulators subject to a certain constraint brought about by the desired trajectory and geometric constraint show high nonlinearity and coupling in their dynamic characteristic. Therefore, it is hard to build dynamical equation with

Necessary Condition for an Euler-Lagrange Equation on Time Scales
We prove a necessary condition for a dynamic integrodifferential equation to be an Euler-Lagrange equation. New and interesting results for the discrete and quantum calculus are obtained as particular cases. An example of a second order dynamic equation,

Simple method to the dynamic modeling of industrial robot subject to constraint
It is a common movement type in industrial production for the end-effector of industrial robot executing tasks according to desired track. High nonlinearity and coupling are shown from the dynamic characteristic of industrial robot because of the ...

On the variational principle in the unfolded dynamics
The interplay between off-shell and on-shell unfolded systems is analyzed. The formulation of invariant constraints that put an off-shell system on shell is developed by adding new variables and derivation in the target space, that extends the original Q-
