Robot Generalization: Why Two-Finger Grippers Struggle with Egocentric Human Data

Explores why egocentric human data alone may not readily transfer to robotic policies using different end effectors like two-finger grippers.

The author emphasizes the need to distinguish between cross-embodiment generalization and cross-end-effector generalization, noting that the latter is substantially harder. Therefore, the primary question when designing a robot foundation model must be: what class of manipulation end effectors is it meant to support?
