In order to achieve long-range homing, the features' trajectories are organized in a visual memory during the execution of the "prior" path. ...
The method assumes that the robot tracks visual features in panoramic views of the environment that it acquires as it moves. ...
In Section 3 the construction and the employment of the visual memory for long-range homing are described. ...

Despite this constancy, efficient home-range foraging trajectories were less diffusive by virtue of restricting locomotive search and spending more time instead scanning the environment to plan movement ...

Our results imply that pigeons process their visual environment on a characteristic spatial scale while navigating and can explain the different degrees of success in reproducing route learning in different ...
Pigeons have also been observed to be particularly attracted to strong linear features in the landscape, such as roads and rivers. ...
This poses the question of whether there is an optimal density of information in the landscape over which a bird is homing for the formation or processing of visual memories. ...

We implement this framework on a robotic platform and test it in a series of environments in which local navigation methods fail. ...
The region from which agents can successfully reach home is therefore limited to the goal's visual locale, that is, the area around the goal where the visual scene is not radically different to the goal ...
However, the LLN framework could be applied to any view-based correspondence homing method that parses visual input into distinct features. ...

In a robot-centered smart home, the robot observes the home states with its own sensors, and then it can change certain object states according to an operator's commands for remote operations, or imitate ...
To model the robot's imitation of the operator's behaviors in a dynamic indoor environment, we use multi-relational chains to describe the changes of environment states, and apply inverse reinforcement ...
For long-term monitoring of hierarchical environment states, two models are closely related. ...
