J In general, teleoperation implies continu ous perceptive and cognitive human operator involvement in the control of remote manipulators. Typically, the human control is a manual / — . one, and the basic information feedback is through visual irna~ Continuous human operator v’ involvement in teleoperation has both advantages and disadvantages. The disadvantages become quite dramatic when there...

Time delayed teleoperation has been one of the first and most challenging topics in robotic control. Although numerous methods have been developed by researchers all over the world during the last two decades, those methods have limitations or need special assumptions to be applied. With the development of the world-wide-web, teleoperation through the Internet sees a bright future. However, the...

For a pneumatic teleoperation system with on/off solenoid valves, sliding-mode control laws for position and force, ensuring low switching (open/close) activity of the valves are developed. Since each pneumatic actuator has two pneumatic chambers with a total of four on/off valves, sixteen possible combinations (“operating modes”) for the valves’ on/off positions exist, but only seven of which ...

We are working to develop an information gathering system comprising a mobile robot and a wireless sensor network (WSN) for use in post-disaster underground environments. In the proposed system, a mobile robot carries wireless sensor nodes and deploys them to construct a WSN in the environment, thus providing a wireless communication infrastructure for mobile robot teleoperation. An operator th...

|A new approach to the design of teleoperation systems is presented. It is proposed that the teleoperation slave be a coarsene manipulator with a ne-motion wrist identical to the teleoperation master. By using a combination of position and rate control, such a system would require only small operator hand motions but would provide low mechanical impedance, high motion resolution and force feedb...

We consider teleoperation in which a slave manipulator, seen in one or more video images, is controlled by moving a master manipulandum. The operator must mentally transform (i.e. rotate, translate, scale, and/or deform) the desired motion of the slave image to determine the required motion at the master. Our goal is to make these mental transformations less taxing in order to decrease operator...

In critical scenarios, the interaction forces between a robot and environment could lead to damages dangerous situations. Complex tasks like grasping fragile objects or physical human-robot in collaborative robotics require capability of controlling forces. bilateral teleoperation, force feedback is used provide telepresence operator. such situation, commonly measured by force/torque sensor at ...
