In recent years, commercial and research interest in service robots working everyday environments has grown. These devices are expected to move autonomously crowded environments, maximizing not only movement efficiency safety parameters, but also social acceptability. Extending traditional path planning modules with socially aware criteria, while maintaining fast algorithms capable of reacting ...

Localization and mapping has been a long standing area of research, both in neuroscience, to understand how mammals navigate their environment, as well robotics, enable autonomous mobile robots. In this paper, we treat navigation inferring actions that minimize (expected) variational free energy under hierarchical generative model. We find familiar concepts like perception, path integration, lo...

x2 c3 c1 x1 Figure 4: Translating move operations in paths sponding sequence of move operations; this task can be performed with diierent modalities, as the same path can in general be described by several move operation sequences. We will investigate the extension of the interface in order to allow direct translation of move operation sequences into a format which is directable executable by t...

Autonomous navigation of a robot in an agricultural field is a challenge as the robot is in an environment with many sources of noise. This includes noise due to uneven terrain, varying shapes, sizes and colors of the plants, imprecise sensor measurements and effects due to wheel-slippage. The drawback of current navigation systems in use in agriculture is the lack of robustness against such no...

Fuzzy Traversability Index is introduced in this paper as a new and simple measure for quantifying the ease of traversal of natural terrains by field mobile robots. This index provides a simple means for incorporating the terrain quality data into the robot navigation strategy, and is used for terrain-based navigation of field mobile robots. The Traversability Index is expressed b y fuzzy sets ...

Autonomous navigation of a mobile robot is a challenging task. Much work has been done in indoor navigation in the last decade. Fewer results have been obtained in outdoor robotics. Since the early 90's, the Global Positioning System (GPS) has been the main navigation system for ships and aircrafts. In open fields, satellite navigation gives absolute position accuracy. The absolute heading info...

Human-robot interaction most challenging task such as control, monitoring and navigation. We explore the unique challenges posed by the remote operation of robots. Teleoperation widely make use of short messaging service, this method not efficient for robotic control, monitoring and navigation. Rapid development in robotic technology effective monitoring, control and automated navigation are ne...

An example of autonomous generation of a topological map for the EDN Navigation System is described on this paper. This algorithm has been tested in a real robot. The EDN Navigation System consists of a sensorimotor and sensorial skills succession, which will guide the robot to its final destination. This succession of actions and events is stored as a topological map called Navigation chart. I...
