Trajectory Track<strong>in</strong>g<br />

Figure 17 shows the trajectory tracked of an experiment similar to the one shown<br />

<strong>in</strong> Section 5.1 i.e. the human operator was <strong>in</strong>duc<strong>in</strong>g only the movement forward.<br />

The results are the same: the robot changes the trajectory automatically near the<br />

top edge due to the computer <strong>in</strong>tervention and stops at the left edge as <strong>in</strong>tended.<br />

At Figure 18 there are four photo saved from the camera above the playground<br />

of the mov<strong>in</strong>g robot at the presented trajectory. The last frame 18(d) shows clearly<br />

that the robot has stopped before the edge not touch<strong>in</strong>g it.<br />
