Orchard Sprayer Tower Dynamics

ORCHARD: Orchard Sprayer Tower Dynamics is a comprehensive Matlab tool designed to simulate and animate the nonlinear stochastic dynamics of an orchard sprayer tower moving on an irregular terrain. The terrain is emulated by a stationary Gaussian random process, providing realistic and valuable insights into the dynamic behavior of the sprayer tower. Developed with an educational approach, ORCHARD is intuitive and user-friendly, making it accessible for researchers and engineers in mechanical and agricultural engineering.
