Opis:: The work presents dynamics of a system of two wheeled mobile robots cooperating in the transport of large-size cargo in the form of a beam. The purpose of modeling of such a system was to obtain a mathematical model in an applicable form. Lagrange equations of the second type were used to describe dynamics, and then the projective method was used to eliminate Lagrange multipliers. Thanks to this approach, unknown dry friction forces at the contact points of robot wheels with the ground were eliminated from the description, and dynamics in controllable coordinates was obtained. In addition, the obtained model has structural properties that enable its use in synthesis of a control system based on the mathematical model.

Opis:: This paper presents a distributed algorithm for the Circle Formation problem under the infinite grid environment by asynchronous mobile opaque robots. Initially, all of the robots acquire distinct positions, and they must form a circle over the grid. The movements of the robots are only restricted along the grid lines; they do not share any global coordinate system. The robots are controlled by an asynchronous adversarial scheduler that operates in Look-Compute-Move cycles. The robots are indistinguishable by their nature, and they do not have any memory of their past configurations nor previous actions. We consider the problem under a luminous model, where robots communicate via lights; other than that, they do not have any external communication systems. Our protocol solves the Circle Formation problem using seven colors. A subroutine of our algorithm also solves the Line Formation problem using three colors.
