The dual-arm work sits between manipulation research and later locomotion papers. It addresses whole-body balancing, task-space torque control, online gravity estimation, and direct teaching of upper-body robots interacting with humans or heavy objects.
This track matters in the new site because it shows how the research evolved from hand-level contact control to larger articulated systems that still require the same care around balance, gravity compensation, and physically plausible interaction.
The public version is intentionally concise, but the page gives enough context to understand how these papers support the broader robotics profile rather than appearing as leftover archive material.
