Performing some special tasks using electrooculography (EOG) in daily activities is being developed in various areas. In this paper, simple rotation matrixes were introduced to help the operator move a 2-DoF planar robot manipulator. The EOG sensor, NF 5201, has two output channels (Ch1 and Ch2), as well as one ground channel and one reference channel. The robot movement was the indicator that ...

The study deals with the automatic chamfering for the case of hole on a free curved surface on the basis of CAD data, using an industrial robot. As a chamfering tool, a rotary-bar driven by an electric motor is mounted to the arm of the robot having six degrees of freedom in order to give an arbitrary position and attitude to the tool. The robot control command converted from the chamfering pat...

A surface walking/climbing robot is developed based on a simple planar 8-bar locomotion mechanism using four 2-way linear cylinders and four 2-way gripper modules. The robot may traverse a fixed distance or turn at a fixed angle after completing a series of repetitive cylinder and gripper actions termed gaits. Symmetric arrangement of the actuators decouples the translation and rotation of the ...

In this paper, a piezoelectrically actuated four-bar mechanism with two flexible links is proposed to be used in a micromechanical flying insect robot wing thorax for stroke amplification. PZT-5H and PZN-PT based unimorph actuators are utilized at the input link of the four-bar for a compact and light weight thorax transmission mechanism. The kinematics and dynamics of the proposed wing structu...

This paper proposes a method to autonomously select stable visual landmarks from observed features by stereo vision and a given 2D obstacle map. The robot selects as stable landmarks vertical line segments which are distinct and on a vertical plane, because they are expected to be observed reliably from various viewpoints. Due to the vision and motion error of the robot, the observed feature po...

A practical architecture, using a four-bar-linkage, is considered for the University of Minnesota direct drive robot [8]. This staticallybalanced ~t drive robot has been constructed for stability analysis of the robot in constrained manipulation [5 -7]. As a result of the elimination of the gravity forces (without any counter weights), smaller actuators and consequently smaller amplifiers were ...

This technical paper describes the implementation of the User Interface for ProVAR, a desktop assistive rehabilitation robot. In addition to mediating interactions between the user and the real-time robot controller, the interface is responsible for the management of a world model and the high level validation of task deployment. The user may perform task planning, simulation and execution thro...

The main objective of this paper is to introduce a new intelligent optimization technique that uses a predictioncorrectionstrategy supported by a recurrent neural network for finding a near optimal solution of a givenobjective function. Recently there have been attempts for using artificial neural networks (ANNs) in optimizationproblems and some types of ANNs such as Hopfield network and Boltzm...

This paper describes the method employed to track and identify each robot during a Robocup match. Also, the playing ball is tracked with almost no extra processing effort. To track the robots it is necessary the use of adequate markers so that not only the position is extracted but also the heading. We discuss the difficulties associated with this problem, various possible approaches and justif...
