Reliability testing

Definition

Reliability testing is the process of evaluating a robotic system's performance and stability over time to ensure that it consistently operates as intended without failure. This type of testing helps identify any potential weaknesses or defects in the system, allowing for improvements to be made before deployment. It involves stress tests, environmental tests, and operational tests to simulate real-world conditions that the robot may encounter.
