In this article, a new fully fuzzy approach is developed for the evaluation based on distance from average solution (EDAS) multi-criteria decision-making (MCDM) using spherical sets (SFSs). The proposed avoids current limitations and drawbacks of distance-based methods in general EDAS method particular information namely, early defuzzification, flaws measures, undefined subtraction division ope...

In this study, the dynamics and control aspects of a spherical robot rolling without slipping on an inclined plane are investigated. The planar dynamic model of the robot rolling ahead on an inclined plane is derived using Lagrangian dynamics. Based on the equivalent control method and Lyapunov stability theorem, a decoupled sliding mode control approach is presented for stable control of the p...

We present a view-based method for steering a robot in a network of positions; this includes navigation along a prerecorded path, but also allows for arbitrary movement of the robot between adjacent positions in the network. The approach uses an upward-looking omnidirectional camera; even a very modest quality of the optical system is sufficient, since all views are represented in terms of low-...
