The paper introduces Visual Learned Distance (VLD), a framework that separates perception from policy learning for image-goal navigation. VLD trains a self-supervised distance-to-goal predictor on thousands of hours of video, then uses a reinforcement learning policy trained in simulation with a learned noise model (GeoNoise) to mimic the predictor’s errors. At deployment, the policy uses VLD predictions zero‑shot, achieving high success rates in simulated environments and on a physical robot without retraining.

The paper introduces a reinforcement learning post‑training scheme that trains robot world models on their own autoregressive rollouts, using a contrastive RL objective adapted from diffusion models. It also proposes a training protocol that compares multiple variable‑length futures, a multi‑view visual fidelity reward, and demonstrates state‑of‑the‑art rollout fidelity on the DROID dataset, outperforming baselines on LPIPS, SSIM, and human preference tests.

The paper proposes a reward-based policy that relies only on rewards and actions, enabling zero‑shot transfer between source and target environments with entirely different observation spaces. Experiments on Pointmass, Cartpole, 2D Car Racing, and the Stretch robot in Habitat‑Sim show that the policy can adapt to new visual styles or 3D renderings without additional samples. Additionally, the reward policy can guide the training of an observation‑based policy in the target environment.

TerraTransfer++ demonstrates a demonstration‑free, end‑to‑end autonomous driving framework that leverages self‑play in vectorized simulators to pretrain a policy. The method distills self‑play rollouts into a flow‑matching trajectory teacher and trains lightweight adapters on a frozen vision backbone, using action KL divergence, a batch‑relational low‑rank loss, and trajectory‑matching loss. The resulting closed‑loop policy surpasses all published imitation‑based methods on the HUGSim benchmark, while the planner achieves state‑of‑the‑art performance on NAVSIM navhard and navtest without any human demonstrations.
