HACARUS Check

HACARUS is a Japanese AI company that provides HACARUS Check, a visual inspection suite for manufacturers. The website lists backers including Mitsubishi Electric, Daikin, Osaka Gas and Miyako Capital, and states the company has supported customers since 2014.

The AI software trains on small sets of good-only images and highlights defects with bounding boxes and heat maps. It is sold as software with Python, C++ and C# SDKs, or as a turnkey system on FANUC CRX cobots (single-sided 180 degree or fully automated 360 degree inspection). Targets include die castings, metal cylinders, plastic parts and circuit boards.

• Good-only learning: models train on a few dozen normal images without defect data.
• Defect visualisation: bounding boxes and heat maps show where defects are.
• FANUC CRX system: turnkey cobot inspection cell with 5 MP camera and multi-way LED lighting.
• 360 degree inspection: two-robot configuration images complex 3D parts from all sides.
• SDK and GUI: Python, C++ and C# libraries plus a Windows GUI.
• Flexible licensing: annual developer license or one-time run-time license.

Inspection of die-cast and machined metal parts at Vietnamese suppliers. Soldering and completeness checks on circuit boards at electronics plants. Surface inspection of plastic parts for automotive tier-2 suppliers.

Training needs only good-part images, so no defect samples must be collected. Minimum detectable defect size is stated as 0.1 mm. A case study reports a 66% reduction in manual inspections at a die-casting maker. No GPU is required on the recommended PC, lowering hardware cost.

Defect samples are scarce in most factories, so good-only learning lowers the barrier to AI inspection. Collaborative robots with cameras are spreading as a flexible alternative to fixed inspection stations. Vietnamese die-casting, machining and electronics plants face the same labour and quality pressures.

Japanese company backed by Mitsubishi Electric, Daikin, Osaka Gas and Miyako Capital. Reference customers include DENSO TEN and BMW Startup Garage. Has a Partner Portal for integrators and distributors. Founding year not stated on the site.
