A collection of interactive 2D physics simulations built using Pymunk (physics engine) and Pygame (rendering). These scripts visualize fundamental concepts in mechanics, chaos theory, and statistics.

This chaotic-looking "double pendulum" follows a large number of rules that govern its motion. Researchers have trained AI to take data from its movements to uncover simple equations that successfully ...

Abstract: This paper proposes a control strategy with guaranteed transient performance for double pendulum crane systems. This control strategy not only completes the control objectives, but also ...

Abstract: This article studies the trajectory planning problem for aerial transportation systems. Current research mainly focuses on the trajectory planning for quadrotor and single-pendulum aerial ...
