LADDER: A Long-Horizon Robot Manipulation Benchmark
LADDER: A Long-Horizon Robot Manipulation Benchmark
LADDER is a new benchmark for long-hor,izon robot manipulation, designed to evaluate the performance of policies across extended tasks. The study shows that general-purpose policies degrade rapidly on long-horizon tasks, while orchestration methods like tool selection with GPT-Policy show better performance but remain limited by low-level execution errors.

We evaluate two orchestration paradigms: text subgoals for learned low-level policies (VoLo) and tool selection orchestration (CaP-X, GPT-Policy, PSP-Agent, TiPToP).

arXiv:2610.18053v1 Announce Type: new Abstract: General-purpose robot manipulation policies learn short-horizon skills effectively, but degrade rapidly on long-horizon tasks. Existing benchmarks cannot isolate failures because task horizon is either too short or entangled with scene and object variations. We propose LADDER, a long-horizon robot manipulation benchmark scaling from 1 to 10 subgoals within the same envi

e-subgoal tasks, but drop to near zero on extended tasks. While orchestration remedies this, it remains bounded by physical execution errors of the low-level policy rather than high-level planning and achieves only ~25%. Tool selection orchestration with GPT-Policy on GPT-6 Astra significantly outperforms learned-policy methods, but incurs significant time and cost budget and succeeds only ~62%. Real-world experiment
