The parts tables describe different robots

The bill of materials separates 5 V, 12 V and wired builds, and distinguishes a base-only price from a system including the two-arm teleoperation set. The battery-powered build lists a Raspberry Pi 5 with 4 GB RAM. In the wired route, LeRobot's guide says to run the commands on the laptop and skip the Pi installation. [S005] [S008]

The 12 V assembly includes a converter supplying 5 V to the Pi, while the 5 V route uses a different power-bank holder and wiring arrangement. Select the motors, power supply and printed holder as a matched configuration. The upstream regional price totals exclude printing and vary with time and supplier; no current delivered cost was verified for this review. [S005] [S007]

Printed parts depend on the selected peripherals

The printing guide supplies STL files and reports PLA settings tested by the authors: 15% infill and 0.2 mm layers. Some parts need supports. Camera mounts differ between the documented Arducam and webcam options, and the assembly guide explicitly says another camera may require modified mounts. The follower and leader arms are separate builds assumed by the base assembly instructions. [S006] [S007]

The archive also includes a CAD-exported URDF and meshes. That is useful robot-description material, but it does not establish a validated simulation. The complete Fusion 360 assembly remains an external link and was not preserved here. No parts were printed, assembled or checked for fit. [S001] [S004]

Motor IDs and calibration have different jobs

The preserved LeRobot guide assigns arm motor IDs 1–6 and base wheel IDs 7–9 in a specific mounting order on one robot-side control board. It separately calibrates the leader and follower arms. Its statement that wheel motors do not require calibration refers to that arm-calibration procedure; it does not make the wheel identities and mounting positions arbitrary. [S008]

For the battery-powered route, the robot runs a LeRobot host and the laptop runs the teleoperation client. The guide requires the correct robot IP and device ports and uses the leader arm for manipulation plus keyboard control for the base. It distinguishes recording-control keys from keyboard base driving: base driving requires a supported desktop input session and is not supported by that guide on Wayland or a headless machine. [S008]

The hardware archive and LeRobot archive were preserved independently. Their availability is not a compatibility test between those exact commits. Before reproducing the system, retain the chosen power version, arm revision, camera models, device mappings, calibration files and software revision together. This is an editorial preparation checklist; no robot was configured or driven here. [S002] [S005] [S008] [S009]

Scope of the open files

The hardware repository carries Apache 2.0 terms, as does the separately preserved LeRobot software. The printing guide credits adaptations of external wheel-hub and Pi-case models; their original terms were not reconciled in this review. Purchased servo and controller firmware are also outside the verified source set. No pretrained model or pre-existing dataset is required for the selected teleoperation route, and no learning performance is claimed. [S003] [S006] [S008] [S010]
