Inside Boston Dynamics' Stretch Durability Testing: An Interview with Mechanical Engineer Diane Heinle

Boston Dynamics mechanical engineer Diane Heinle discusses durability testing for the Stretch robot: she is responsible for the dynamic cable design on the Stretch arm, cycling cables millions of times in the lab at speeds and forces far beyond real-world conditions, simulating years of warehouse wear in a matter of weeks. The durability lab is known as the "Tick-Tock Room" because the cable testers swing back and forth like metronomes, and the test data is also used to refine the design and maintenance schedules, avoiding downtime at customer sites.
