Electric Excavator Arm with Integrated AI

Presentation:

The Electric Excavator Arm with Artificial Intelligence is an educational product designed based on the real system for teaching industrial engineering sciences.

This educational product is intended for use in CPGE PCSI/PSI - PTSI/PT, TSI and ATS courses.

The articulated arm has three position-controlled axes (with speed loop) to enable autonomous excavation work.

Each axis is controlled by an electric actuator and is equipped with an incremental encoder and a force sensor to cover the following points in the program:

• Servo control (characterization, identification, modeling, correction)
• Geometric/kinematic law in closed and open chains
• Statics
• Dynamics/Energy/Power.
• Python programming (state diagram)
• AI processes

The control software, MyViz:

• a 3D model that can be controlled in real time, replicating the actual dynamics of the system (digital twin)
• a control mode in Python (via high-level commands)
• an autonomous control mode using Artificial Intelligence

Educational activities:

TP1: DISCOVERING SYSTEMS - Identify the components of an excavator arm

TP2: MODELING AND PERFORMANCE OF SLCI  - Manipulate the arm while following the operator's instructions as closely as possible.

Lab 3: STUDY OF SOLID SYSTEMS - Connect the operator's actions (control of the cylinders) to the movements of the arm (joints).

TP4: FREQUENCY ANALYSIS

TP5 : STATIC STUDY - Relate the forces to be exerted by the cylinders to the configuration of the arm and the force to be exerted on the bucket.

TP6: CHOICE OF A CORRECTOR - Enable optimal behavior of the excavator arm (safety, productivity)

TP7: ENERGY STUDY

TP8: AI – AUTONOMOUS EXCAVATOR - Make the excavator autonomous in its operation, taking into account its environment
