Launch HN: Bucket Robotics (YC S24) – Defect detection for molded and cast parts

Aug 28, 2024 - news.bensbites.com
Bucket Robotics, a startup by Matt and Steph, has launched a defect detection system for molded and cast parts in manufacturing. The system uses CAD models to create custom defect detection models, replacing the traditional method of manual or ML-based defect detection. The system generates these models by creating variations of the 3D model to simulate defects and innocuous elements like ejector pin marks. The models are then used to render photorealistic scenes, which are used to train a vision model for defect detection.

The defect detection model can be run on basic hardware and operates on-site, ensuring customer images do not leave the worksite. The startup charges customers per model and aims to have the model ready before retooling is complete when a line change to a new mold is planned. The founders have a background in automating manual tasks and have previously worked on self-driving cars at Argo AI, Latitude AI, and Stack AV.

Key takeaways:

  • Bucket Robotics has launched a new product that uses CAD models to create custom defect detection models for manufacturing, specifically for injection molded and cast parts.
  • The defect detection models are created by generating a large number of variations of the 3D model, simulating various defects and then training a vision model from these images.
  • The model doesn't require high-end hardware and runs purely on-device, ensuring customer images don't need to leave their worksite. The company charges customers per model.
  • Bucket Robotics was founded by Matt and Steph, who have a history of working on tasks performed manually that they want to automate, including self-driving cars at Argo AI, Latitude AI, and Stack AV.
