* feat(robots): natively integrate Seeed Studio reBot B601-DM arm Add first-class LeRobot support for the Seeed Studio reBot arm, replacing the out-of-tree `lerobot-robot-seeed-b601` / `lerobot-teleoperator-rebot-arm-102` plugin packages. New devices: - robot `rebot_b601_follower` — single-arm B601-DM follower (6-DOF + gripper, Damiao CAN motors via `motorbridge`) - robot `bi_rebot_b601_follower` — bimanual follower composing two single arms - teleoperator `rebot_102_leader` — single-arm StarArm102 / reBot Arm 102 leader (FashionStar UART servos via `motorbridge-smart-servo`) - teleoperator `bi_rebot_102_leader` — bimanual leader composing two single arms The bimanual variants reuse the single-arm classes and namespace each arm's observation/action keys with `left_` / `right_` prefixes, so a bimanual StarArm102 leader can teleoperate a bimanual reBot B601 follower. Optional SDK imports are guarded; a `rebot` extra installs `motorbridge` and `motorbridge-smart-servo`. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs: add reBot B601-DM calibration & dual-arm teleoperation guide Add docs/source/rebot_b601.mdx covering single-arm and bimanual calibration and teleoperation for the reBot B601-DM follower and reBot Arm 102 leader, with zero-position reference images from the Seeed Studio wiki. Register the page in the docs toctree. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs: fix reBot B601 MDX build (move JSON example out of <Tip>) The doc-builder parses `{...}` inside MDX component children as a Svelte expression, so the joint_directions JSON example broke the build. Move it into a top-level fenced code block. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs: apply prettier formatting to reBot B601 page Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs: remove duplicate colocated reBot B601 page docs/source/rebot_b601.mdx is the canonical, toctree-registered page; the colocated rebot_b601.md was a redundant thinner copy. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs: clarify 6-DOF leader fallback comment in reBot B601 follower Explain that holding wrist_yaw at zero is what lets a 6-DOF leader (e.g. so100_leader / so101_leader) teleoperate the 7-DOF follower. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * refactor: address Caroline's PR review on reBot B601 integration - leader: remove _validate_config (no other lerobot device validates its config; a key mismatch now surfaces as a plain KeyError) - leader: simplify _round_to_valid_range to direct modular arithmetic instead of a bidirectional search loop - leader: inline the single-use _clamp helper - follower & leader: write MotorCalibration range_min/range_max from the configured joint_limits / joint_ranges instead of a fixed [-90, 90] - docs: add a "Find the USB ports" section (lerobot-find-port) and move the brltty/permissions tip there; link the OpenArm page for SocketCAN adapter configuration Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
