In this paper, we propose a newly developed suspension system called “Pentad Grade Assist Suspension (PEGASUS)”. PEGASUS has high mobility as well as rocker-bogie suspension, with very simple mechanism called only-one-joint architecture. PEGASUS is able to successfully climb up on the stepalike terrain with low energy consumption by scale model test. The prototype of micro planetary rover Micro...

In this paper, dynamic and stability analysis of a flexible cam-follower system is investigated. Equation of motion is derived considering flexibility of the follower and camshaft. Viscous and Coulomb frictions are considered in the rocker arm pivot. The normalized equation of motion of the system is a 2nd- order differential equation with periodic coefficients.&#10Floquet theory is employed to...

Abstract The full-heavy tetraquarks $$cc{\bar{c}}{\bar{b}}$$ c ¯ b and $$bb{\bar{b}}{\bar{c}}$$ are systematically investigated within a quark model. meson–meson structure, diquark–antidiquark structure K-structure considered in...

1 Objective Foot ulcer is one of the main challenges of diabetic patients influencing their abilities to stand and walk. Various methods have been suggested to decrease the loads applied to the foot in this group of patients; most methods were not deemed successful and could only be used temporarily. Rocker shoes are recommended for foot ulcer treatment. Based on the available literature, it is...
