# Model Card for Model ID
Classification of lego technic pieces under basic room lighting conditions

## Model Details

### Model Description
CNN designed from the ground up, without using a pre-trained model to classify images of lego pieces into 7 categories. <br>
Achieved a 93% validation accuracy

- **Developed by:** Aveek Goswami, Amos Koh
- **Funded by [optional]:** Nullspace Robotics Singapore
- **Model type:** Convolutional Neural Network

### Model Sources

- **Repository:** https://github.com/magichampz/lego-sorting-machine-ag-ak

## Uses
The tflite model (model.tflite) was loaded into a Raspberry Pi running a live object detection script. <br>
The Pi could then detect lego technic pieces in real time as the pieces rolled on a conveyor belt towards the Pi Camera
