A double pendulum consists of two pendulums attached to each other, and is a classic physical system that exhibits complex and chaotic motion. The balancing problem of double pendulum using only a single motor on the first joint is a well-known benchmark in control theory and robotics. This po...
MuJoCo (Multi-Joint dynamics with Contact) is a physics engine mainly developed by Emo Todorov and maintained by Google DeepMind. It is widely used in robotics, reinforcement learning research, and biomechanics. This post covers installation on macOS, importing model, and running simulations i...
Camera calibration is a fundamental step in many computer vision applications, from 3D reconstruction to augmented reality. It involves estimating the intrinsic parameters of a camera (like focal length, principal point, and lens distortion) and its extrinsic parameters (rotation and translati...
