Thus Figure 4 shows the behavior of the robot when ap- proaching a sound source with an induced bias in its motor output that makes the left wheel turn 20% faster than the right. Without the optomotor response the robot had some difficulty reaching the speaker: with the response added it successfully and directly reached the speaker on all but one trial. Because the two hardware sensor systems are well tuned to executing their specific tasks, it was relatively simple to combine the behaviors to produce a robust per- formance without any explicit representation of the "fused" auditory and visual Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
