We present a real-time smoothing methodology for the stabilization of videos captured from small robotic helicopter platforms. We suppress supposedly unintended vibrations considering relative rotation and displacements between successive frames. We propose a similar, an affine or a bilinear transformation to model global motion assuming that camera movement dominates the motion field of aerial footage...
Two robots collaboratively search a street area. At an abstract level, this is the well-known two-guard street walk problem. Variations of the problem, i.e., general walk, straight walk, counter walk, straight counter walk, have been studied. In this work, deepening our previous work on simple characterizations of walkable streets, we consider the generation of optimal walk schedules by two robots.
In this paper, a system capable of obtaining the 3-D pose of a mobile robot using a ring of calibrated cameras attached to the environment is proposed. The system robustly tracks point fiducials in the image plane of the set of cameras generated by the robot's rigid shape in motion. Each fiducial is identified with a point belonging to a sparse 3-D geometrical model of the robot's structure. Such...
In this paper a real time obstacle detection system for robots is presented. The technique is based on a single camera and no further sensors or encoders are required. The algorithm is independent of geometry and even moving objects can be detected. The system provides a top view map of the robotpsilas field of view in real-time. First, the images are segmented reasonably. Ground motion estimation...
Despite those the inverse dynamics methods in traditional robotics, few are eligible to be applied to systems with as high degrees of freedom (DOFs) as humans. Few tackle the intricacies of the human musculoskeletal system itself. We propose a two-phase motor control model based on the equilibrium point hypothesis, which takes advantage of the muscle spring system to control human movements. The motor...
