External IROS paper validates whole-body stabilizer on UBTECH Walker in simulation

Evidence notes
- The IROS 2021 paper proposes a force-feedback whole-body stabilizer for position-controlled humanoid robots.
- The authors demonstrate the stabilizer on the UBTECH Walker robot in MuJoCo simulation, reporting improvements over ZMP-feedback and linear-inverted-pendulum stabilizers.
