This file contains a model of a backhoe arm built using Simscape. The hydraulic actuation system, including pump, valves, and hydraulic cylinders, actuates the arm and bucket. The three-dimensional mechanical system is modeled, including the arm joints and bucket linkage. Examples in this submission show how to model custom hydraulic valves, tune controller and physical system parameters, and generate C code from the entire model.

@Iryna - which release are you using? I do not think I have ever seen that error message before. --Steve
Hello! I have a problem with bucket modeling .. when I start the simulation of the file "Backhoe_Arm" error: "Error in 'Backhoe_Arm/Arm/Bucket Assembly/Bucket/Attachment Frame/Attachment Plates/Left Hole Transform': This proxy block was inserted in the model because a block of type 'SimMechanicsBlock' could not be located during model load. Updating or simulating a model containing such a proxy block is not permitted". Help me please run the simulation.
Very Good Example.
