2013年4月1日 · Locusts (Locusta migratoria manilensis) are characterised by their flying ability and abiding jump ability. Research on the jumping mechanics and behavior of locusts plays an important role in elucidating the mechanism of hexapod locomotion. The jump gestures of locusts were observed using high-speed video camera at 250 fps.

A locust (hopper or adult) jumping to escape predators has different requirements. If it does not jump far enough or fast enough it will be captured. Thus it is worth investing a large amount of energy in a single jump to evade a predator. In addition, the adult locust uses jumping as a means of reaching take-off velocity for flight.

BY means of high-speed flash cinematography it has been shown that the acceleration period of the jumping locust—the time taken to extend the metathoracic legs at their tibio-femoral joints—is...

2010年4月1日 · Simulations demonstrated that the SLP can significantly increase jump distance, power, total energy and duration of the jump impulse. In addition, the geometry of the joint enables the SLP force to assist leg flexion when the leg is flexed, and to assist extension once the leg has begun to extend.

This paper relates the mechanics of the extensor tibiae muscle to the energy storage capacity of the jumping leg of the locust. The load-deformation relationships for the semilunar processes of locusts of different ages are measured and related to the form of the legs.

Locusts (Schistocerca gregaria) jump using a latch mediated spring actuated system in the femur-tibia joint of their metathoracic legs. These jumps are exceptionally fast and display angular rotation immediately after take-off.

2008年3月29日 · Locusts propel their jumps by rapid movements of their long hind legs powered by contractions of femoral muscles extending the tibiae. They can control the speed, azimuth, and elevation components of their take-off velocities to jump precisely towards targets (Eriksson 1980; Sobel 1990; Collett and Paterson 1991; Santer et al. 2005).

Targeted jumps by a locust, which are powered by a rapid extension of the tibiae of both hind legs, require control of the take-off angle and speed. To determine how the locust controls these parameters, we used high speed imag …

Jumping locomotion is an ideal means of overcoming obstacles and traversing rough terrain. By taking inspirations from the locust, this paper presents the development and analysis of a novel… ... Proceedings of the Royal Society of London…

2005年7月26日 · Locusts can direct their escape jumps up to 50° either side of the direction of their long axis at the time of hindleg flexion, allowing them to consistently jump away from the side towards which an object is approaching.
