Abstract:

Abstract—The use and effect of deliberate head movements in fish have not been extensively studied, possibly due to the long-held assumption that this motion is a recoil effect from undulatory tail movements. Recent findings from fish experiments and numerical simulations suggest that correct phase and amplitude regulation of head movements can improve swimming efficiency, as well as provide advantages to other physiological systems within the fish. However, these findings have yet to
tested on fish robots, which are useful testing platforms allowing
systematic exploration of effect of head movements via accurate
measurements of thrust production and energy expenditure. This paper presents a research plan and preliminary design of an untethered fish robot to study whether deliberate head movements can improve swimming efficiency.
