Considerable attention has recently been given to the new environment-friendly refrigerant of R1234ze(E) for applications such as heat pump and air-conditioning systems. In this study, an experiment was carried out to investigate two-phase flow patterns and flow transitions for R1234ze(E) in a smooth horizontal tube with an inner diameter of 6 mm. The experiments were performed at conditions covering...
This work lays the foundations of a self-collision aware teleoperation framework for compound robots. The need of an haptic enabled system which guarantees self-collision and joint limits avoidance for complex robots is the main motivation behind this paper. The objective of the proposed system is to constrain the user to teleoperate a slave robot inside its safe workspace region through the application...
In this paper we present an interactive system to enhance bilateral teleoperation through online virtual fixtures generation and task switching. This is achieved using a stereo camera system which provides accurate information of the surrounding environment of the robot and of the tasks that have to be performed in it. The use of the proposed approach aims at improving the performances of bilateral...
In this paper we present a vision-based system for online virtual fixture generation suitable for manipulation tasks using remote controlled robots. This system makes use of a stereo camera system which provides accurate pose estimation of parts within the surrounding environment of the robot using features detection algorithms. The proposed approach is suitable for fast adaptation of the teleoperation...
In electronic manufacturing system, the design of the robotic hand with sufficient dexterity and configuration is important for the successful accomplishment of the assembly task. It is significant that the robot can grasp assembly parts and do some simple in-hand manipulation so as to fit them with the package slots. In this research, we study the process of precise in-hand posture transition problem...
High flexibility and high speed is the goal for industrial manufacturing using robots. However, it is difficult to put them together due to the fact that they are contradicting with each other. To solve this problem, a new high reconfigurable gripper is proposed for robotic manipulator to improve its flexibility, so that the robot can accomplish an assembly task with shorter time. In this paper, the...
In electronic manufacturing system, the design of the robotic gripper is important for the successful accomplishment of the assembly task. Due to the restriction of the architecture of traditional robotic hands, the status of assembly parts during the assembly process cannot be effectively detected. In this research, an intelligent robotic gripper - i-Hand equipped with multiple small sensors is designed...
In human and robot cooperated electronics manufacturing system, correctly mating connectors by robot, not human, is vital for the improvement of overall performance. Although static force model has been established based on force and position information during mating, there are some difficulties should be overcome to implement a mating process monitoring task on deformable PCBs. For this purpose,...
A robotic wiring harness assembly system, basing on vision and force/torque sensors, is developed to realize mating of electric connectors. In this system, cameras are firstly used to detect the position and the pose of a grasped connector, and then the corresponding bias is calculated roughly to guarantee the connector can be contacted with the other opposite part. After that, a force/torque sensor...
