Current obstacles

Sim-to-real transferRobots trained in simulation often fail in real factories due to differences in lighting, materials, and part variations not captured in training.
Scaling to diverse tasksA model trained for one assembly task may not work for a different part or process; building generalizable systems is a major engineering challenge.

Physics limits

Data annotation at scaleTraining models requires labeled factory data. At the scale of thousands of robots and millions of operations, labeling becomes a bottleneck.
Latency and real-time controlIndustrial robots need sub-100ms response times. Running large ML models on edge hardware while meeting real-time constraints is challenging.

How it works

4 parts

Fleet deployment

Robots in Rivian plants

Mind Robotics deploys robots in Rivian's own manufacturing facilities, where they perform assembly and material handling in production environments.

Data collection

Factory sensors and logs

Sensors on production lines and robots, plus manufacturing execution system logs, capture data about task execution, outcomes and environmental conditions.

Machine learning

Training on operational data

Models are trained on the collected factory data to predict what actions succeed in different contexts. Models improve as more data is collected.

Continuous improvement

Deployment drives learning

As robots operate, new data feeds back into the training pipeline. The deployed fleet improves over time, and improvements can be pushed to all robots.
