This project implements a production-grade machine learning pipeline that monitors multi-dimensional sensor data (vibration, temperature, torque, and rotational speed) and uses a random forest classifier to identify potential structural anomalies in robot joints before catastrophic failures occur.

In the field of industrial automation, unexpected failures of mechanical equipment often lead to costly downtime losses and potential safety risks. Traditional periodic maintenance strategies can reduce failure probability, but they have issues of over-maintenance (wasting resources) or under-maintenance (still having failure risks). Predictive Maintenance monitors equipment status in real-time and predicts potential failures, allowing intervention before problems worsen, thus optimizing maintenance costs and improving equipment availability.
This project targets a six-axis industrial robot joint driven by a brushless DC motor and a harmonic reducer. Such high-precision actuators are widely used in manufacturing, with complex failure modes and high costs.
Section 04
The system records joint status through four continuous telemetry channels:
Section 05
Mechanical oscillations are monitored via a three-axis accelerometer mounted on the joint's output bearing housing. High vibration amplitudes usually indicate issues such as bearing race pitting, misalignment, or gear tooth surface spalling.
Section 06
Measured using an RTD sensor embedded near the motor stator windings. During normal operation, the temperature maintains a thermal equilibrium below 55.0°C. A temperature rise usually indicates friction loss, current overload, or lubrication failure.
Section 07
Captured via a series strain gauge torsion sensor, measuring the mechanical force exerted by the actuator. Fluctuations indicate changes in the drag coefficient or joint resistance.
Section 08
The angular velocity of the main shaft is measured using a high-resolution optical shaft encoder.
