A robot assembly pipeline reaches over 95% success on busbar tasks

A modular perception, planning, and impedance-control pipeline achieved over 95% success on busbar assembly with a 160-second cycle time; connector insertion required specialist pose estimation and custom gripper fingers. The results offer concrete lessons for building reliable robotic automation.

What: NVIDIA’s Seattle Robotics Lab and Isaac team built robotic systems for GB300 tester-tray busbar assembly and multi-connector insertion.
How: A pipeline using FoundationPose, waypoint planning, Lissajous-curve manipulation primitives, and impedance control exceeded 95% busbar success at a 160-second cycle time.
Why it matters: Custom gripper fingers constrained part motion to make grasp poses more repeatable without tactile sensors or in-hand manipulation.

The modular pipeline used for busbar assembly, from perception through control. Sketched from the article's own text.
