Based on the flatness property of the robot's kinematic model , we proposed a dynamic feedback linearization controller in combination with attitude and velocity observers. The proposed control-observer scheme requires only Cartesian position measurements and achieves asymptotic trajectory tracking. The ...
In general applications, most manipulators, with the position and/or velocity controllers, may be constrained by the environment. In this case, it subsequently generates a contact force. In the robust controller, any external force is considered a disturbance and, consequently, Experimental setup ...

Selection of the lateral modeDepending on the velocity$v$the time based ($d(t)$) or running length / arc length based ($d(s)$) lateral planning mode is activated. By projecting the start state onto the reference curve the the longitudinal start position$s(0)$is determined. The frenet ...
Non-prehensile pivoting utilizing contacts from the environment was also implemented with hybrid force–velocity control [21]. Most control-based in-hand manipulations have been realized by visual or/and tactile feedback or a parallel-jaw gripper customization. The objective of this paper is the ...
The inverse kinematic Cartesian controller at the velocity level is given by 𝑋˙=𝐾(𝑋𝑑−𝑋),X˙=KXd−X, (13) where 𝐾K is the diagonal gain matrix with positive values on the main diagonal and 𝑋𝑑Xd is the commanded Cartesian position. A Cartesian controller with ...
