OpenDM-format BF16 checkpoint for ARX5 on RoboChallenge Table 30 v2. Use with OpenDM third_party/robochallenge_inference (configs/generalist/arx5.yaml). See the DM05 RoboChallenge Table 30 v2 Inference Guide.

Weights: BF16 model.safetensors.

Model Card

Table30 Tasks

arrange_flowers, hang_the_cup, pick_out_the_green_blocks, press_the_button, turn_on_the_light_switch, water_the_flowers, wipe_the_table

Per-task horizon overrides: third_party/robochallenge_inference/configs/generalist/arx5.yaml → task_overrides.

Use with OpenDM RoboChallenge Inference

The RoboChallenge client now lives in OpenDM at third_party/robochallenge_inference (configs/generalist/arx5.yaml). See the DM05 RoboChallenge Table 30 v2 Inference Guide.

# From the OpenDM repository root.
export OPENDM_ROOT=/path/to/opendm
pip install -e ".[fast-infer]"

cd third_party/robochallenge_inference
export ARX5_CHECKPOINT=/path/to/DM05-ARX5
export ARX5_NORM_STATS=${ARX5_CHECKPOINT}/norm_stats.json
pip install -r requirements.txt

python execute.py --config-name generalist/arx5 \
  user_id=YOUR_USER_ID \
  submission_id=YOUR_SUBMISSION_ID

Override without env vars:

python execute.py --config-name generalist/arx5 \
  checkpoint=/path/to/DM05-ARX5 \
  norm_stats=/path/to/DM05-ARX5/norm_stats.json \
  user_id=YOUR_USER_ID \
  submission_id=YOUR_SUBMISSION_ID

If ARX5_NORM_STATS is unset, the client falls back to ${ARX5_CHECKPOINT}/norm_stats.json.

Runtime Profile

From third_party/robochallenge_inference/configs/default.yaml → robot_profiles.arx5:

• action_type=leftpos, action_mode=relative, single_arm_target=eef
• history_mode=logical_step, history_max_frames=5
• speed=0.5, add_state=true
• attn: llm/action sdpa, vision flash_attention_2
