Summary
According to a post on X by @OWW, two robotics papers address how robot control models are built and trained. SPAR, from Shenli Zheng, Li Du and colleagues, structurally prunes vision-language-action models and then recovers their action quality, with the stated aim of producing faster robot policies that run on cheaper hardware. A second paper, from Shuyuan Hu, Bo Zhao and colleagues, reduces spurious coupling between the two arms in bimanual imitation learning so that robots learn the task rather than the timing of the demonstrations. The post also links to additional material that the provided snippet does not describe.

Why it matters
Teams building robot policies could get a path to smaller models that need less expensive hardware, if the pruning approach holds up. Work on bimanual imitation learning matters for anyone training two-armed robots, since it targets learning the task itself rather than incidental demo timing. Watch for published results and benchmarks that show whether these gains carry over to real robots.
