Otherwise, the heading of the agent is inverted in case of obstacle at front.
In case of an obstacle very close to the mid range finder (basic element 3), an evasive turn action is provided (7, 12, 15, 16, 19, 20, 22).
In both cases we assume that the robot knows some a priori response to low level sensors (i.e. to contact sensors in the case of obstacles or to proximity target sensors in the case of targets) and has to learn the response to high level stimuli (i.e. distance sensors or visual input).
The results show the ability of the time reversal technique to focalize impulsive waves back at the origin, even in the case of obstacles to the wave propagation.
Traditional computer algorithms tend to not produce a useful result until they are complete (which may be too late in case of avoiding an obstacle for instance).
In case of the line and obstacle do not collide, the Euclidean distance of the two points would be considered.
In case of As-based ChG, this obstacle can be suppressed under partial As-to-Sb replacement [19].
Out-of-pocket costs are the main obstacle to medical treatment, especially in case of diseases with a long natural history (such as breast cancer).
The reshaping strategy modifies the velocity of the robot to match three requirements: i) to increase the human safety in case of close interaction with the robot, ii) to guarantee the correct task execution in case of unforeseen obstacles (including the human), and iii) to replan online the current task taking into account the human behavior.
