Water strider can slide agilely on water surface at high speed. To study its locomotion characters, movements of water strider are recorded by a high speed camera. The trajectories and angle variations of water strider leg are obtained from the photo series, and provide basic information for bionic robot design. Thus a water strider robot based on surface tension is proposed. The driving mechanism...
We present a new approach to autonomous navigation for humanoid robots in previously unknown environments. Our method uses only on-board cameras and does not rely on color coding, textured surfaces or predefined object models. We propose using a reactive approach towards navigation that does not require building an explicit model of the environment. The basic idea of the navigation system is to check...
This paper introduces a visual servoing scheme for humanoid walking. Though most of the existing approaches follow a perception-decision-action scheme, we close the loop so that the control is robust to model error. Our approach is based on a new reactive pattern generator which modifies, at the control level, the footsteps, the center of mass and the center of pressure trajectories for the center...
This work presents some results obtained from image processing and motion analysis of the human body. The issues raised in motion analysis are of interest for obtaining motion-specific parameters for movements of the human body. The resulting data (spatial coordinates, velocities and accelerations) are used for further processing in humanoid robotics and assistive and recuperative technologies for...
Localization in multi-robot systems is a key problem in multi agent systems. In many cases, specially involving legged robots, like the Robocup soccer competition, it relies on predefined landmarks at known locations. However, when several objects are in motion, vision occlusions due to agents in the field of view make this kind of localization unfeasible for mild time periods. This also happens if...
Trajectories followed by the humans can be interpreted as an attitude gesture. Based on this interpretation an autonomous mobile robot can decide how to initiate interaction with a given human. In this work is presented a modular control system to analyze human walking trajectories in order to engage a robot on a Human-Robot interaction. When the robot detects a human with their vision system a visual...
