Robots are booming as an essential substituent in the field of inspection. In hazardous environments like nuclear waste disposal, robots are really a necessitate one. In a view to meet such demands, this paper presents the seven degree of freedom articulated inspection robot. To design such a robot the kinematic analysis of seven Degree of freedom robot which can inspect the hazardous nuclear w...

In this paper, the uncertain dynamic parameters of an experimental target tracker robot are identified through the application of genetic algorithm. The considered serial robot is a two-degree-of-freedom dynamic system with two revolute joints in which damping coefficients and inertia terms are uncertain. First, dynamic equations governing the robot system are extracted and then, simulated nume...

'The regulation problem for articulated mechanical arms is often solved by designing simple control laws which strongly exploit the physical properties of the system. It is well known that a rigid robot can be globally asymptotically stabilized around a given joint configuration via a P D controller on the joint errors, provided that gravity is exactly cancelled by feedback [l]. Under a mild co...

BACKGROUND Snake-like robot is an emerging form of serial-link manipulator with the morphologic design of biological snakes. The redundant robot can be used to assist medical experts in accessing internal organs with minimal or no invasion. Several snake-like robotic designs have been proposed for minimal invasive surgery, however, the few that were developed are yet to be fully explored for cl...

Developing an environment that enables optimal and flexible design of robot manipulators using reconfigurable links. joints. actuators, and sensors is an essential concept towards efficient robot design and prototyping Such an environment should have a complex set of software and hardware subsystems for designing the physical parts and the controllers, and for the algorithmic control of the rob...

In this paper, dynamic equations of motion of a 5 DoF robot manipulator including mechanical arms with revolute joints and their electrical actuators are considered. The application of integrator backstepping technique for trajectory tracking in presence of parameters of uncertainty and disturbance is studied. The advantage of this control technique is that it imposes the desired properties of ...

This paper proves the capability of the bees algorithm to solve complex parameter optimization problems for robot manipulator control. Two applications are presented. The first case considers the modelling of the inverse kinematics of an articulated robot arm using neural networks. The weights of the connections between the nodes need to be set so as to minimize the difference between the neura...

Accurate pose estimation of object instances is a key aspect in many applications, including augmented reality or robotics. For example, a task of a domestic robot could be to fetch an item from an open drawer. The poses of both, the drawer and the item have to be known by the robot in order to fulfil the task. 6D pose estimation of rigid objects has been addressed with great success in recent ...

New generation robots, meant for physical human robot interactions, are no longer rigid; it has become soft in terms of introduction of considerable flexibility at the actuated joints, flexibility of the links and in terms of compliant coverings. Safety requirement becomes primary in situations where physical interactions occur, calling for compliance; but accuracy and control bandwidth get com...
