Exploration using Voronoi diagrams
Sabine Hauert
21 Sep 2010
How can a robot explore and make maps of new environments while avoiding obstacles?
One way is to let the robot remain at equal distance from its two nearest obstacles, thereby navigating exactly in b...
Robot formations that avoid obstacles
Sabine Hauert
13 Sep 2010
In formations, robots are positioned at a precise distance and sometimes angle from one another to form shapes. Robots that advance in formations can share communication, computation and sensing resou...
Adaptive bipedal walking on slopes
Sabine Hauert
06 Sep 2010
Imagine walking on a flat surface with your eyes blinded. If the slope below your feet changes, you’ll most likely change your posture to keep moving. To explain this, an idea from the 1950s say...
Social learning
Sabine Hauert
29 Aug 2010
Robots are portrayed as tomorrows helpers, be it in schools, hospitals, workplaces or homes. Unfortunately, such robots won’t be truly useful out-of-the-box because of the complexity of real-wor...
Local visual homing
Sabine Hauert
24 Aug 2010
How can a robot, using vision, go back to a previously visited location?
Möller et al. look at this research question, tagged “Local Visual Homing” in an intuitive manner inspired from so...
RFID-based global positioning
Sabine Hauert
14 Aug 2010
Having a robot figure out its global position is required in many real world applications, it’s also one of the biggest challenges in robotics.
The easiest approach is to have a robot blindly ke...
Human-like arm movements
Sabine Hauert
06 Aug 2010
Many robots are required to move like humans. Human-like motion is useful to efficiently interact with humans and environments built for them, make realistic humanoids or replace actual limbs (prosthe...
Contour extraction for mapping
Sabine Hauert
29 Jul 2010
To map their environment, robots typically collect large amounts of range and bearing measurements to walls around them. However, when using noisy sensors, additional efforts need to be done to extrac...
Learning tasks across different environments
Sabine Hauert
27 Jul 2010
In the future, robots will be expected to learn a task and execute it in a variety of realistic situations. Reinforcement-learning and planning algorithms are exactly intended for that purpose. Howeve...
Classifying dynamic obstacles
Sabine Hauert
24 Jul 2010
Identifying dynamic objects in urban environments has become a major concern with the advent of autonomous cars in industry and competitions such as the Darpa Urban Challenge. However, detecting and c...
Vision, force and touch for manipulation
Sabine Hauert
22 Jul 2010
Manipulating objects is still a major challenge for robots in human-centered environments. To overcome this hurdle, Prats et al. propose to combine vision, force and tactile sensing to achieve robust ...
Vision-based navigation with motion blur
Sabine Hauert
20 Jul 2010
Robots often need to know where they are in the world to navigate efficiently. One of the cheapest ways to localize is to strap a camera on-board and extract visual features from the environment. Howe...
