Bioinspired Implementation and Assessment of a Remote-Controlled Robot

Figure 1

(a) Schematic representation of the robot (top view) designed for the study. Two independent motors drive the front wheels, and a third one controls the rotation of the pan camera. This mobile vision is implemented by default to promote a visual anticipation over the change of direction. (b) Illustration of the camera behavior in some specific locations of the path. The blue arrow indicates the instantaneous direction of the vehicle and the red arrow represents the orientation of the pan camera at the same moment. It is notable that the angle between the two arrows is inversely proportional to the radius of curvature of the robot trajectory. The more curved is the shape of the path (e.g., position 2), the larger is the angle between the orientation of the camera and the direction of the vehicle, and vice versa (e.g., position 4).
