This paper presents Wadoro (WAtch DOg RObot); an autonomous mobile robot for household surveillance in open-spaces like roof at night; but only shaded areas such as verandah during daytime. The robot has the capability to detect humans in near real-time round-the-clock using passive infrared motion sensors and camera. The work cycle of the robot is divided into phases of human detection; tracking;...
Service robots share the living space of humans. Thus, they should have a similar concept of the environment without having everything labeled beforehand. The detection of closed doors is challenging because they appear with different materials, designs and can even include glass inlays. At the same time their detection is vital in any kind of navigation tasks in domestic environments. A typical 2D...
This paper presents an implementation of detecting and recognizing typical obstacles with laser range finders. Mounting the laser range finder with a pitch angle on top of the robot, we can obtain the height information of the obstacle. Techniques, such as clustering, line segment extraction, coordinate transformation, line segment matching, are then applied on the scan data analyzing to detect and...
