Plain language
A robot test task where an arm pushes a T-shaped block into a target position.
As stated in the literature
A contact-rich manipulation benchmark requiring an arm to push a T-shaped block into a goal pose, used as a real-world robot-learning task in fleet-scaling experiments.
Why it matters: Its constant contact and precise goal make it a demanding real-world test of whether a learned manipulation skill actually works.
For example, a robot arm has to nudge a T-shaped block from a sloppy starting spot into an exact target outline.

“In the Push-T task — pushing a T-shaped block into place — going from one agent to eight cut time-to-target from roughly five hours down to about two.”Episode 159 — Can a Coding Agent Run Its Own Robot Experiments Overnight, With No Human Resetting the Scene?
