Coupled Rigid Bodies, Impulsive Dynamics, Applications - Trap Jaw Ants, Leaping Lizards, Falling Cat
Explore advanced dynamics applications in this 55-minute lecture covering coupled rigid bodies, impulsive dynamics, and fascinating biological systems. Delve into the unusual behavior of rolling and spinning bodies, multi-rigid body systems like the acrobot, and conservation of angular momentum with examples ranging from astronaut reorientation to how cats land on their feet. Examine gyro-stabilization in ships and spacecraft, impact dynamics in passive dynamic walking and jumping toys, and the ballistic jaw propulsion of trap-jaw ants. Conclude with an analysis of continuous systems with changing geometry, such as flying snakes, modeled as quasi-rigid bodies. Gain insights into the intersection of physics and biology, with potential applications in robotics and engineering design.
