Immersive Teleoperation Of A Robot Arm Using Electro-Tactile Feedback, Daniel Pamungkas, Koren Ward
Immersive Teleoperation Of A Robot Arm Using Electro-Tactile Feedback, Daniel Pamungkas, Koren Ward
Faculty of Engineering and Information Sciences - Papers: Part A
2015 IEEE. Teleoperation can allow an operator to control a robot remotely in inaccessible and hostile places. To achieve more dexterous control of a tele-operated robot some researchers are developing user interfaces equipped with vision and tactile feedback. 3D visual perception and tactile feedback can also assist the operator to feel immersed in the robot's environment and embodied within the robot to some extent. Most existing tactile feedback systems use electro-mechanical actuators and linkages. However, these systems are complex, cumbersome and consequently make it difficult for the operator feel embodied within the robot. To improve on these drawbacks, this paper …
Electro-Tactile Feedback System For Achieving Embodiment In A Tele-Operated Robot, Daniel Pamungkas, Koren Ward
Electro-Tactile Feedback System For Achieving Embodiment In A Tele-Operated Robot, Daniel Pamungkas, Koren Ward
Faculty of Engineering and Information Sciences - Papers: Part A
Tele-operation can enable an operator to control a robot remotely in inaccessible and hazardous environments. However, controlling a robot remotely via a conventional monitor and control panel can be difficult and slow. To achieve faster and more dexterous operation of the robot, enhanced 3D perception and some form of tactile or neural feedback is needed to achieve some degree of embodiment within the robot's physical structure and world. To achieve this objective we have devised an immersive tele-operation system comprised of a stereo vision headset and an electro-tactile feedback system that is worn by the operator, connected to stereo cameras …
Electro-Tactile Feedback For Tele-Operation Of A Mobile Robot, Daniel Pamungkas, Koren Ward
Electro-Tactile Feedback For Tele-Operation Of A Mobile Robot, Daniel Pamungkas, Koren Ward
Faculty of Engineering and Information Sciences - Papers: Part A
It is well known that haptic feedback can facilitate the tele-operation of a remotely controlled robot by providing the user with intuitive tactile and/or force sensations from the robot's interactions with the environment. However, such mechanical haptic feedback systems can be complex, cumbersome, costly and application specific. This paper presents a novel tele-operation haptic feedback system that overcomes many of these limitations by providing electro-tactile feedback to the operator via wireless electrodes placed on the operator's skin. We show that this form feedback can provide a viable substitute for force and tactile feedback systems without the need for mechanical linkages …
Tele-Operation Of A Robot Arm With Electro Tactile Feedback, Daniel S. Pamungkas, Koren Ward
Tele-Operation Of A Robot Arm With Electro Tactile Feedback, Daniel S. Pamungkas, Koren Ward
Faculty of Engineering and Information Sciences - Papers: Part A
Tactile feedback from a remotely controlled robotic arm can facilitate certain tasks by enabling the user to experience tactile or force sensations from the robot's interaction with the environment. However, equipping both the robot and the user with tactile sensing and feedback systems can be complex, expensive, restrictive and application specific. This paper introduces a new tele-operation haptic feedback method involving electro-tactile feedback. This feedback system is inexpensive, easy to setup and versatile in that it can provide the user with a diverse range of tactile sensations and is suitable for a variety of tasks. We demonstrate the potential of …

Performance Analysis Of Numerical Integration Methods In The Trajectory Tracking Application Of Redundant Robot Manipulators, Emre Sariyildiz, Hakan Temeltas
Faculty of Engineering and Information Sciences - Papers: Part A
Differential kinematic is one of the most important solution methods in robot kinematics. The main advantage of the differential kinematic method is that it can be easily implemented any kind of mechanisms. Also, an accurate and efficient kinematic based trajectory tracking application can be easily implemented by using this method. In differential kinematic method, we use Jacobian as a mapping operator in the velocity space. Inversion of Jacobian matrix transforms the desired trajectory velocities, which are the linear and angular velocities of the end effector, into the joint velocities. The joint velocities are required to be integrated to obtain the …

A Comparison Study Of The Numerical Integration Methods In The Trajectory Tracking Application Of Redundant Robot Manipulators, Emre Sariyildiz, Hakan Temeltas
Faculty of Engineering and Information Sciences - Papers: Part A
Differential kinematic has a wide range application area in robot kinematics. The main advantage of the differential kinematic is that it can be easily implemented any kind of mechanisms. In differential kinematic method, Jacobian is used as a mapping operator in the velocity space. The joint velocities are required to be integrated to obtain the pose of the robot manipulator. This integration can be evaluated by using numerical integration methods, since the inverse kinematic equations are highly complex and nonlinear. Thus, the performances of the numerical integration methods affect the trajectory tracking application. This paper compares the performances of numerical …
Solution Of Inverse Kinematic Problem For Serial Robot Using Dual Quaterninons And Plucker Coordinates, Emre Sariyildiz, Hakan Temeltas
Solution Of Inverse Kinematic Problem For Serial Robot Using Dual Quaterninons And Plucker Coordinates, Emre Sariyildiz, Hakan Temeltas
Faculty of Engineering and Information Sciences - Papers: Part A
In this paper we present a new formulation method to solve kinematic problem of serial robot manipulators. In this method our major aims are to formulize inverse kinematic problem in a compact closed form and to avoid singularity problem. This formulation is based on screw theory with dual - quaternion. Compared with other methods, screw theory methods just establish two coordinates, and its geometrical meaning is obvious. We used dual-quaternion in plücker coordinates as a screw operator for compactness. 6R-DOF industrial robot manipulators forward and inverse kinematic equations are derived using this new formulation and simulation results are given.
