Sentences with phrase «bioinspired robotic fish»

By using a reliable, consistent, and remotely controlled robotic platform, we test the hypothesis that, at a constant swimming velocity, a bioinspired robotic fish is able to elicit attraction in a live fish as a consequence of the visual and flow cues it offers.

Fish preference for a given condition was taken as proportional to the time spent in the vicinity of the bioinspired robotic fish and measured for the focal region, as well as for each compartment comprised in both the Top and Side views.

Experimental results show that the time spent by golden shiners in the vicinity of the bioinspired robotic fish is the highest when the robot mimics their natural color pattern and beats its tail at the same frequency.

Furthermore, post-hoc comparisons revealed that fish spent significantly more time in the vicinity of the bioinspired robotic fish as its tail - beat frequency was set to 3 Hz (185.8 s) as compared to the case when the robot tail - beat frequency was 0 Hz or 2 Hz (121.3 s or 132.7 s, respectively).

Not exact matches

In this work, we employ two prototypes of robotic fish, whose engineering design was bioinspired to mimic the aspect ratio, body shape, size, and species - specific locomotion pattern observed in live golden shiner.

Our results show that fish positional preference is affected by the color of the robotic fish, whereby a prototype with a bioinspired color pattern (Gray robot) is more attractive than a red replica (Red robot).

The bioinspired colored robotic fish prototype (referred to as «Gray robot») was painted with a light gray color, and the fins were shaded gray while a black line was drawn along its longitudinal length.
