Remarks on multimodal nonverbal interface and its application to controlling mobile robot
This paper proposes a multimodal nonverbal interface system using bio-potential signals, such as EOG and EMG, and image processing and investigates its possibility of applying to control a mobile robot. To evaluate the feasibility and the characteristics of the multimodal nonverbal interface system, teleoperation control experiments of the robot are carried out. By comparing the experimental results with those obtained using a conventional keyboard interface, the effectiveness of the proposed interface system is confirmed.
Combining a Brain-Machine Interface and an Electrooculography Interface to perform pick and place tasks with a robotic arm
This paper presents a multimodal Human-Machine Interface system that combines an Electrooculography Interface and a Brain-Machine Interface. This multimodal interface has been used to control a robotic arm to perform pick and place tasks in a three dimensional environment. Five volunteers were asked to pick two boxes and place them in different positions. The results prove the feasibility of the system in the performance of pick and place tasks. By using the multimodal interface, all the volunteers (even naive users) were able to successfully move two objects within a satisfactory period of time with the help of the robotic arm. A multimodal HMI to perform pick and place tasks with a robotic arm is presented.The EOG interface is applied to control planar movements and to operate the gripper.The BMI is used to control the height of the gripper through two mental tasks.The system had been tested by five healthy subjects.The results prove the feasibility of the system in the performance of these tasks.
Thermodynamic Evaluation of Solar Integration into a Natural Gas Combined Cycle Power Plant
The term integrated solar combined-cycle (ISCC) has been used to define the combination of solar thermal energy into a natural gas combined-cycle (NGCC) power plant. Based on a detailed thermodynamic cycle model for a reference ISCC plant, the impact of solar addition is thoroughly evaluated for a wide range of input parameters such as solar thermal input and ambient temperature. It is shown that solar hybridization into an NGCC plant may give rise to a substantial benefit from a thermodynamic point of view. The work here also indicates that a significant solar contribution may be achieved in an ISCC plant, thus implying substantial fuel savings and environmental benefits.
