Presentation:

T-Dac is designed to automatically distribute cards and is based on an architecture combining mechanical parts and sensors for educational purposes.

Composition:

Mechanical elements:
- 3D-printed mechanical parts (Multi Jet Fusion process)
- Industrial mechanical components

Instrumented functional chains:
- Orientation (positioning facing the player): transmission via bevel gears, angular position control (incremental encoder)
- Ejection (sending the card to the player): transmission via pulleys/belt, speed control (incremental encoder), presence of card at the output detected by a distance sensor

Educational activities:

STI2D:

- Identify and characterize the functions and components of a product as well as its inputs/outputs
- Study the elements of the power chain of the two sub-assemblies: card orientation and ejection
- Observe the behavior of the system in operation in order to identify the components of the power and information chains

SI:
- Analyze the power transmission of the two sub-assemblies
- Measure the angular positioning of the T-Dac in different configurations (angular setpoint, full/empty card reservoir, etc.)
- Identify the components and functions of the card ejection roller speed control system
- Adjust the PID controllers in real mode using a set of values specified in the practical assignment and perform card ejection tests
- Quantify the performance differences between the expected values and the measured values

CPGE:

- Measure the angular position of the distributor in different configurations (angular setpoint, maximum angular speed, full/empty card reservoir) in order to characterize the performance of the system
- Model the components of the orientation chain servo system and simulate its behavior
- Model the components of the ejection chain servo system and simulate its behavior
