We define and implement behaviors for a class of such tasks that we call continuous area sweeping tasks. A continuous area sweeping task is one in which a robot (or group of robots) must repeatedly visit all points in a fixed area, possibly with non-uniform frequency, as specified by a task-dependent cost function. Examples of problems that need continuous area sweeping are trash removal in a large building and routine surveillance. We present a formulation for this problem and an initial algorithm to address it. The approach is analyzed analytically and is fully implemented and tested, both in simulation and on a physical robot","PeriodicalId":428475,"journal":{"name":"ICAR '05.

Often such situations are life-threatening and people cannot safely obtain such information. Disasters in urban areas are particularly taxing. Structural collapse, damaged staircases and the loss communication infrastructures aggravate rescue efforts. Robots, equipped with camera, can be employed to visually capture situational awareness. As such, the focus of our work is designing a backpackable aerial robot that can hover-and-stare. Such a robot would ascend, peer through windows, and transmits video to an operator.

Casting and winding with hyper-flexible elements like strings, ropes or wires should be a useful operation to capture a distant target object A multi-link system connected by passive non-elastic joints is employed as a discrete dynamic model of hyper-flexible systems. Casting and winding dynamics is analyzed with the multi-link model. Casting and winding motion can be divided in several phases as casting, contacting, winding and capturing. This paper focuses on the casting motion suitable for winding onto a round target object. Simulations are executed to clarify a suitable casting motion to realize a good and firm winding.

Two robotic rovers that were designed specifically for the extended payload transport task are described.

A set of behaviors has been developed to support the performance of the task, integrating simple sensing with controls. We describe the behaviors and their integration within the overall task structure.

We examine a team of robots with no centralized control performing a transportation task, in which robots frequently interfere with each other. The robots must work in the same space, so territorial methods are not appropriate. Previously we have shown that a stereotyped competition, inspired by aggressive displays in various animal species, can reduce interference and improve overall system performance. However, none of the methods previously devised for selecting a robot's 'aggression level' performed better than selecting aggression at random. This paper describes a new, principled approach to selecting an aggression level, based on robot's investment in a task. Simulation experiments with teams of six robots in an office-type environment show that, under certain conditions, this method can significantly improve system performance compared to a random competition and a noncompetitive control experiment. Finally, we discuss the benefits and limitations of such a scheme with respect to the specific environment","PeriodicalId":428475,"journal":{"name":"ICAR '05.

We will end up with a simple control law which impose the trajectory following for the distance between the foot and the total center of mass and which maintains the CoM above the feet during the whole jump (take-off, flight, land-in).

A significant part of such systems is devoted toward active camera control for efficient target tracking. DynaTracker is a pan-tilt device based active camera system for maintaining continuous track of the moving target, while keeping the same at a pre-specified region (typically, the center) of the image. The significant contributions in this work are the use of mean-shift algorithm for visual tracking and the derivation of the error dynamics for a proportional-integral control action. The stability analysis and optimal controller gain selections are performed from the simulation studies of the derived error dynamics. Simulation predictions are also validated from the results of practical experimentations.

In this paper, we present a system capable of learning robot tasks from demonstration. Classical robot task programming requires an experienced programmer and a lot of tedious work. In contrast, programming by demonstration is a flexible framework that reduces the complexity of programming robot tasks, and allows end-users to demonstrate the tasks instead of writing code. We present our recent steps towards this goal. A system for learning pick-and-place tasks by manually demonstrating them is presented.

An operator uses virtual world simulator to make command path. The virtual environment of this simulator is constructed with measurement data from a rover. We have, however, a communication delay between the control station and the remote site. So, there is the difference between old map data which operator used for path planning and new data, which a rover is tracking on. The operator's path command has less reliability to avoid obstacles and to reach the goal. Therefore, to make high reliability of operator's command, we propose command-data compensation (CDC), which compensates this difference as the distortion of the environmental map","PeriodicalId":428475,"journal":{"name":"ICAR '05.
