Could you build this?
No This project implements mathematical trajectory optimization and Time-Varying Linear Quadratic Regulators (TV-LQR) using CasADi for non-linear crane dynamics, requiring advanced control theory domain expertise.
What it would actually take: Building this requires a strong background in mechanical engineering and advanced control theory. The system requires deriving the nonlinear differential equations of motion for a suspended pendulum crane passing through spatial constraints, formulating a non-linear programming (NLP) problem in CasADi/IPOPT for optimal trajectory planning, and implementing continuous-time TV-LQR feedback control over the linearized time-varying trajectory to guarantee stability against disturbances.
