Abstract EN
Ontogenetic locomotion research focuses on the evolution of locomotion behavior in different developmental stages of a species.
Unlike vertebrates, ontogenetic locomotion in invertebrates is poorly investigated.
Locusts represent an outstanding biological model to study this issue.
They are hemimetabolous insects and have similar aspects and behaviors in different instars.
This research is aimed at studying the jumping performance of Locusta migratoria over different developmental instars.
Jumps of third instar, fourth instar, and adult L.
migratoria were recorded through a high-speed camera.
Data were analyzed to develop a simplified biomechanical model of the insect: the elastic joint of locust hind legs was simplified as a torsional spring located at the femur-tibiae joint as a semilunar process and based on an energetic approach involving both locomotion and geometrical data.
A simplified mathematical model evaluated the performances of each tested jump.
Results showed that longer hind leg length, higher elastic parameter, and longer takeoff time synergistically contribute to a greater velocity and energy storing/releasing in adult locusts, if compared to young instars; at the same time, they compensate possible decreases of the acceleration due to the mass increase.
This finding also gives insights for advanced bioinspired jumping robot design.
