Animals can instantly exhibit versatile behaviors in response to their circumstances to
survive in harsh natural environments. For example, many animals chase prey, escape from …

This work addresses the set-point control problem of the position of fully-actuated
Lagrangian-type robotic systems by means of some nonlinear control laws. We adopt four …

In recent years, legged (quadruped) robots have been subject of technological study and
continuous development. These robots have a leading role in applications that require high …

Legged robots can have a unique role in manipulating objects in dynamic, human-centric, or
otherwise inaccessible environments. Although most legged robotics research to date …

One of the frequent tasks of a robotic system is to go from an initial position to another
location or to change its actual configuration to some desired one. Thus, an efficient as well …

Among the most important tasks, in order to control the robotic system to achieve some
desired goal, is the design of the controller to be applied as well as the right choice of gains …

This paper presents an optimal control architecture for Pegasus, a novel quadruped wheel-
legged robot with hybrid locomotion capabilities. The proposed control architecture …

There have been incredible advancements in robotics and spoken dialogue systems (SDSs)
over the past few years, yet we still don't find social robots in public spaces like train stations …

A distinctive feature of quadrupeds that is integral to their locomotion is the tail. Tails serve
many purposes in biological systems, including propulsion, counterbalance, and …
