....to be done in another simulated robot environment, Roger The Crab . Roger is a bidimensional world simulator imitating a crab which was originally implemented in 1991 to be used as a tool for high level vision research. Roger has been used to develop tools and algorithms for attention control [2], pattern categorization [3] and new models for computer animation [4] Some of these works were the test bed for real time algorithms running in a stereo head [3] The main improvements we introduce are the addition of the third dimension to the world model and to have a more realistic ....
....the information redundancy. 5 Experiments and demonstrations In order to test Cambio s architecture, we have implemented a high level Vergence Controller. The idea is to keep both eyes verged in a place in the world while the robot searches for and or moves to a new focus of interest, as in [2]. A very basic algorithm for changing attention moves the dominant eye , given by some attentional process, so as the vergence point gets as close as possible to the center of its image. Concurrently, the other ( non dominant ) eye s position is adjusted in a loop which tries to minimize the ....

....will be performed as a feedback to the environmental stimuli. This carries out an attentional policy which can be understood as an strategy for choosing the best actions according the current perceptual state. Currently, we developed two policies for the purpose of performing a monitoring task [3, 4]. One is a simple straight forward strategy, a hand coded solution, and the other one was derived by using Q learning [7] In the monitoring task devoted to Roger, as a result of the attentional policies, all regions of interest in the environment are visited (looked at or touched by Roger) and ....
