Although image-based visual servoing provides superior performance in many vision-based robotic applications, it reveals fatal limitations when initial pose discrepancy is large. The feature points may leave the camera’s field of view, and also, the robot may not converge to the goal configuration. In this paper, a novel approach is proposed to resolve these limitations by planning trajectories...

In space applications, it is conceivable that part of the robotic activities could involve the grasp and/or manipulation of free-floating objects in absence of gravity. In this case, synchronous application of contacts seems to represent a basic feature in order to efficiently grasp the floating items. In this sense, an additional difficulty is that objects may have irregular shape and/or be no...

This paper presents a study to experimentally evaluate a new design paradigm for robotic components, with emphasis on space robotics applications. In this design paradigm, robotic components are made from embedded binary actuators and compliant mechanisms in order to reduce weight and complexity. This paper presents a series of five experiments that demonstrate the concept. These studies includ...

The goal of this project was to design and implement the electronics for a robotic device – namely a robotic manipulator. The manipulator has a total of six degrees of freedom, three of which are on the manipulator itself, and the rest are in the wrist. A gripper is used as the end stage of the device. It was necessary to design the electronics so that they could be interfaced with standard har...

In this paper we present the swing-up regrasping problem where an object is manipulated using a robotic arm around a point pinched by the arm’s gripper. The aim of the regrasping is to manipulate the object from an initial angle to regrasp it on a new desired angle relative to the gripper. The pinching point functions as a semi-active joint where the gripper is able to apply only frictional tor...

Smart materials have been widely used for control actuation. A robotic hand can be equipped with artificial tendons and sensors for the operation of its various joints, mimicking human hand motions. The motors in the robotic hand could be replaced with novel electroactive polymer (EAP) actuators. In the three-finger gripper proposed in this paper, each finger can be actuated individually so tha...

Industrial robots become useless without end-effectors that for many instances are in the form of friction grippers. Commonly friction grippers apply frictional forces to different objects on the basis of programmers’ experiences. This puts a limitation on the effectiveness of gripping force that may result in damaging the object. This paper describes various stages of design and development of...
