A fast variant of the iterative closest points (ICP) algorithm registers 3D scans taken by a mobile robot into a common coordinate system and thus provides relocalization. Hereby, data association is reduced to the problem of searching for closest points. Approximation algorithms for this searching, namely, approximate kd-trees and box decomposition trees, are presented and evaluated in this paper. A solution to 6D SLAM that considers all free parameters in the robot pose is built based on 3D scan matching","PeriodicalId":428475,"journal":{"name":"ICAR '05.

The kinematics and weighted redundancy resolution to support suturing in confined spaces, such as the throat, is developed and experimental validation in presented. The kinematics of the hybrid system is described in an 8-dimensional augmented vector space composed from the joint variables of the six DoF robot and two angles describing the configuration of the snake-like unit.

However, most robot control architectures make some assumptions about how sensory information relates to motor actions, in order to provide a set of basic behaviors (such as reflexes). It is largely unknown to what extent these biases reduce the potential for the generation of diverse or unexpected behaviors from the agent-environment interaction. In this paper, we propose a new model of robot control architecture, consisting of homogeneous, non-hierarchical coupling, which only learns the correlation of simultaneous activity between any pair of sensor or motor modalities. We show that the propagation of activity across the different modalities, modulated by the learnt correlations, can lead to the emergence of coherent complex behaviors, such as approaching and following an object, or solving a task based on the temporal relationship between an early clue and a delayed reward","PeriodicalId":428475,"journal":{"name":"ICAR '05.

However, unnecessary large volumes of communication data may still lead to big time delay and energy waste. This paper addresses the problem of how to reduce the data exchange among multiple robots when they carry out cooperative area exploration or coverage. In this application, multiple robots need exchange map information in order to minimize the repeated exploration or coverage. When a connected ad hoc network can not be maintained, the map data exchange or synchronization should be carefully dealt with in order to reduce the volume of data exchange. In this paper, a novel sequence number-based map representation scheme and an effective robot map update tracking scheme are proposed. Based on them, an algorithm is developed to reduce the volumes of map data exchange when robot subnetworks merge.

It is shown that the oscillator-based controller can operate with a once per cycle feedback, while the model-based controller requires high-rate state feedback. However, a consequence upon the oscillator-based control with low-rate feedback is a smaller stability regime in its parameter space. Hence it may be necessary to use the model-based controller with high-freq feedback to stabilize the system initially. Once the system is stabilized, it is possible to switch to the oscillator-based controller, which can keep the system stable against minor disturbances even with low-rate feedback. This is demonstrated in the context of yoyo-control, which is periodic and open-loop unstable","PeriodicalId":428475,"journal":{"name":"ICAR '05.

The wheel-arm robot is designed to be a wheel robot with a 4 DOF arm that has ability to manipulate small objects and move on flat terrain. The wheel-arm can also reconfigure itself to be a different type of one-wheel robot. By connecting multiple wheel-arm robots in different configurations, the robot group achieves different functionality. This paper provides kinematic analysis for various types of configurations which explains how the change in configuration affects their functionality including numbers of degrees of freedom for locomotion, manipulation, the ability to climb over obstacles and the maximum force exertion.

The work presented here shows the use of a particular swarm of robots called swarm-bot for carrying out distributed missions of fetching and retrieval of objects. To solve this task, a high level description plan defined in terms of behaviors is synthesized. A mission is divided in four different stages: searching for a target, calling for a swarm to aggregate as soon as one is found, jointly fetching it, and jointly retrieving it back. All robots used (s-bots) are assumed to know the same set of behaviors as well as the same behavioral plan for carrying out the task. Units are kept purely reactive, thus they do not keep any memory of their previous history. This allows to withstand changes in a highly dynamic environment. Coordination is achieved asynchronously by using light signals, whereas cooperation for the actual transportation is realized by using a force sensor located between the turret and the tracks of each s-bot. A swarm-bot, which is formed by a group of s-bots physically connected to their target, is capable of behaving during its homeward motion as if it were a single entity. Experiments show the high level of adaptability and resilience of a swarm-bot with respect to occasional possible failures of its members","PeriodicalId":428475,"journal":{"name":"ICAR '05.
