✦ Synopsis

In this paper, we propose a mathematical model for the kinematics of a hybrid robot, called Wheeleg. The wheeled-legged robot has two pneumatically actuated front legs, each with three degrees of freedom, and two rear wheels independently actuated. Based on the proposed model, the dynamics equations of the manipulator are developed using the natural orthogonal complement method. Equations are implemented in an algorithm used to study the kinematics and the dynamics of the mobile robot. Simulations are provided to demonstrate the method developed. Successively, a brief description is given of the control architecture designed and implemented. In conclusion, some experimental tests of the motion on the horizontal plane are reported.

This paper presents the methodology of the kinematic and dynamic modeling for a newly developed parallel robot with the so-called Tau configuration. A set of analytical kinematic solutions has been developed for this parallel structure. A rigid body dynamic model has been formulated based on the pri

By using the integrator backstepping technique, the control of rigid link, electrically driven robot manipulators is addressed in the presence of arbitrary uncertain manipulator inertia parameters and actuator parameters. The control scheme developed is computationally simple owing to the avoidance

The manipulation of a rigid object by two cooperating robots is considered. If only the position of the object is of interest, the inverse dynamic problem is redundant, because the number of available actuators exceeds the number of degrees of freedom of the object.
