CRH's Ash Grove Spot robot deployment in Washington State represents one of the most successful implementations of quadruped robot cement plant inspection in North America. The Boston Dynamics cement inspection program runs over 80 hours weekly, with Spot performing autonomous patrol routes across production zones that would otherwise require human inspectors to navigate hazardous environments filled with cement dust, extreme temperatures, and rotating equipment. In a pivotal early success, the bearing failure detection robot identified thermal anomalies in a critical conveyor bearing three weeks before predicted failure—preventing an unplanned shutdown that would have cost the facility an estimated $180,000 in lost production.

Quadruped Robots for Cement Plant Inspection: Ash Grove CRH Spot Deployment & CMMS
How CRH's Ash Grove cement plant leverages Boston Dynamics Spot with 360-degree camera cement inspection capabilities and Orbit fleet management cement integration to achieve proactive maintenance cement operations that prevent costly failures.
Deployment Overview
The CRH cement robot program at Ash Grove demonstrates how four-legged robot cement mill inspection transforms maintenance operations from reactive to predictive. Spot navigates the plant's challenging terrain—including cement dust-covered grated platforms, stairways, and areas with radiant heat from kiln operations—performing systematic inspection routines that capture thermal, visual, and acoustic data across all production zones.
The Bearing Detection Success
Early Warning Detection
During a routine autonomous patrol, Spot's thermal imaging payload detected elevated temperatures in a conveyor bearing assembly that operates 24/7 transporting raw materials to the mill. The temperature differential—12°C above baseline—was subtle enough that manual periodic inspections had missed it, but Spot's consistent measurement protocol identified the trend over multiple inspection cycles.
Key Finding: The rotating equipment inspection capability identified bearing degradation 3 weeks before predicted failure, enabling scheduled replacement during a planned maintenance window rather than emergency intervention.
Detection Timeline
- Week 1: Initial temperature anomaly detected (+8°C)
- Week 2: Trend confirmed, work order generated (+10°C)
- Week 3: Parts procured, maintenance scheduled (+12°C)
- Week 4: Planned replacement during maintenance window
Prevented Unplanned Downtime
Without robotic detection, the bearing would have failed during production, requiring emergency shutdown, expedited parts procurement, and overtime labor. The cement production uptime impact of such failures typically exceeds $50,000 per day at facilities of this scale. By detecting the issue early, Ash Grove scheduled the repair during an existing maintenance window, avoiding both production losses and premium emergency costs.

Quadruped Robot Maintenance Requirements
Maintaining the robots that maintain your plant requires systematic attention. Dust-resistant robot enclosure care and payload calibration are critical for cement environment operation. Sign up for Oxmaint to track robot maintenance alongside production equipment.
Enclosure Seal Testing
Cement dust infiltration is the primary threat to robot electronics. Regular seal integrity testing and filter replacement prevents internal contamination.
Weekly inspectionThermal Payload Calibration
Prolonged exposure to kiln radiant heat can drift thermal sensor calibration. Regular verification against reference sources maintains measurement accuracy.
Monthly calibrationVibration Sensor Verification
Acoustic and vibration sensors used for bearing failure detection robot functions require accuracy verification against known reference equipment.
Quarterly verificationLeg Actuator Servicing
Navigating cement dust-covered grated platforms and stairways accelerates wear on leg joints and actuators. Regular inspection and lubrication extends operational life.
