In recent years there has been a growing interest amongst Human-Robot Interaction (HRI) researchers in the usage of robotic systems for exploration or search missions [6, 3, 4]. In the traditional approach to robot supervision by humans, knows as camera guided teleoperation [3], the operator navigates the robot while interpreting camera imagery. Both tasks require constant attention, and contri...

This paper describes our work on developing effective, efficient and user-friendly interaction between a human operator and a mobile robot on performing spatial navigation tasks. In order to solve the spatially related communication problems caused by the disparity between human mental representation about spatial environments and that of a mobile robot, a qualitative spatial knowledge based fo...

The objective of this paper is path planning of a 3 DOF planer robot with hydraulic actuator using genetic algorithm. First the geometric and kinematic parameters of robot were established. The equations of motion are derived by Lagrange method. We proposed the model for proportional valve and hydraulic actuators. Then using the genetic algorithm we minimized the hydraulic energy consumption as...

In this paper, a new method was proposed for the navigation of a mobile robot in an unknown dynamic environment. The robot could detect only a limited radius of its surrounding with its sensors and it went on the shortest null space (SNS) toward the goal. In the case of no obstacle, SNS was a direct path from the robot to goal; however, in the presence of obstacles, SNS was a space around the r...

This paper presents results of our educational experiments aimed to raise awareness of freshmen engineering and senior high school students on the importance of spatial skills and develop strategies for spatial learning through practice of remote operation and programming robot systems in automated manufacturing labs. In the first experiment senior high school students performed two assignments...

To examine the relationship of expired capnograms and respiratory system resistance (Rrs) in intubated critically ill patients, we consecutively studied 41 mechanically ventilated patients to (1) analyze the association between expired CO2 slope and auto-positive end-expiratory pressure (auto-PEEP), between Rrs and auto-PEEP, between Rrs and expired CO2 slope, and between Rrs and arterial minus...

This habilitation thesis deals with the broad topic of robot navigation and with its foundations in spatial modeling, scene understanding, and action generation. Robot navigation is the process of autonomously making a sequence of decisions that allows a mobile robot to travel robustly to selected locations in the environment. This ability involves a large set of problems that need to be solved...

We review our progress to date in eliciting dynamically dexterous behaviors from a three degree of freedom direct drive robot manipulator whose real-time stereo cameras provide 60 Hz sampled images of multiple freely falling bodies in highly structured lighting conditions. At present, the robot is capable of forcing a single ping-pong ball into a specified steady state (near) periodic vertical ...
