While professional robotics often use the Jacobian Inverse or Cyclic Coordinate Descent (CCD) , these methods are either too "heavy" for an Arduino or produce jerky, unnatural movements. Today, we are exploring NocKinematics , a lightweight C++ library that brings the industry-standard FABRIK algorithm to the world of microcontrollers. 🔬 The Science: Why FABRIK? NocKinematics is built upon the foundational research of Andreas Aristidou and Joan Lasenby . If you are looking for the academic rigor behind this library, you should refer to the original paper: > Aristidou, A., & Lasenby, J. (2011). "FABRIK: A fast, iterative solver for the Inverse Kinematics problem." Graphical Models, 73(5), 243-260. Why this matters for Embedded Systems: Unlike traditional methods that rely on expensive trigonometric functions or matrix inversions, FABRIK (Forward And Backward Reaching Inverse Kinematics) uses an iterative approach based on finding points on a line.…
