SO-101 (SO-ARM101) is the next version of the SO-100 robot arm, designed by The Robot Studio with Hugging Face. You build a leader arm and a follower arm, move the leader by hand and the follower copies it. It is made to work with the open-source LeRobot library.

What it can do:
- Teleoperate a follower arm with a leader arm
- Record datasets and train policies with LeRobot

## HopeJR
Hugging Face estimated about $3,000 per unit for its 66-DoF open humanoid
Page: https://openrobotkits.com/robots/hopejr/ | API: https://openrobotkits.com/api/robots/hopejr.json
Type: Humanoid | Maker: The Robot Studio + Hugging Face | License: Apache License (Humanoid/LICENSE in the repo; the repo root declares no license)
Build difficulty: 4 of 5 (Advanced). Tendon-driven 16-motor hand, 7-motor arm and an exoskeleton to print, source from Alibaba and calibrate Source: https://github.com/TheRobotStudio/HOPEJr/blob/main/Arm/BOM.md

HopeJR is an open-source humanoid with dexterous hands, designed by The Robot Studio and Hugging Face. The GitHub repo has two parts: the full Humanoid design, and the newer Arm (arm, hand and teleop exoskeleton) wired into LeRobot for recording, training and inference. Hugging Face's 2025 announcement gave about $3,000 per unit as an estimate; no checkable store listing was found.

What it can do:
- Teleoperate the arm and hand with a matching exoskeleton, joint for joint
- Record data, train and run policies through LeRobot
- 3D-print and assemble without soldering (Arm build, custom PCBs)

Stock: diy parts. Checked n/a.

Not included: The maker's Arm BOM lists motors, boards, power supplies, screws, bearings, springs and wire with links but no prices, so no parts total can be given. The only price figure is Hugging Face's ~$3,000-per-unit estimate for the full humanoid (TechCrunch, May 2025, tariff-dependent).

## Berkeley Humanoid Lite
Parts for the full humanoid total $4,312 (US prices), per the Berkeley paper
Page: https://openrobotkits.com/robots/berkeley-humanoid-lite/ | API: https://openrobotkits.com/api/robots/berkeley-humanoid-lite.json
Type: Humanoid | Maker: UC Berkeley Hybrid Robotics | License: Code MIT; other assets CC BY-SA 4.0
Build difficulty: 5 of 5 (Advanced). Hand-assemble 22 cycloidal actuators from motors, ESCs and printed parts, then calibrate and run RL policies Source: https://arxiv.org/pdf/2504.17249

Berkeley Humanoid Lite is an open-source humanoid from UC Berkeley (RSS 2025) with 22 actuators built around 3D-printed cycloidal gearboxes and parts from Amazon and Taobao. The repo covers training, sim2sim, deployment, motion capture and teleoperation; CAD, 3D-print files and the BOM are on the docs Releases page. Plans-only: you source, print and assemble it yourself.

What it can do:
- Locomotion policies trained in Isaac Lab and deployed on the robot
- Teleoperated manipulation and motion capture control
- Reconfigure the same actuators into other forms (paper shows quadruped and biped layouts)

## BCN3D Moveo
Fully 3D-printed, Arduino-driven open-source arm; BOM, CAD and manual on GitHub
Page: https://openrobotkits.com/robots/bcn3d-moveo/ | API: https://openrobotkits.com/api/robots/bcn3d-moveo.json
Type: Robot arm | Maker: BCN3D Technologies | License: MIT
Build difficulty: 4 of 5 (Advanced). Plans only: print all parts, source about 33 component types plus fasteners, wire 6 stepper drivers, load firmware Source: https://raw.githubusercontent.com/BCN3D/BCN3D-Moveo/master/BOM/BCN3D%20Moveo%20BOM.pdf

BCN3D Moveo is a robotic arm whose structure is fully 3D printed and whose electronics are controlled by Arduino. It was built with the Catalan Departament d'Ensenyament for schools. Plans only: BCN3D does not sell it, so you print and source every part yourself.

What it can do:
- Be rebuilt from CAD, STL, firmware and a user manual (English and Spanish)
- Run on an Arduino Mega 2560 with RAMPS 1.4 and 6 stepper drivers (per the BOM)

Stock: diy parts. Checked n/a.

Not included: The official BOM (2-page PDF) lists parts and quantities but no prices, so no total is given. Not a kit: nothing is sold; 3D printing of all structural parts is on you.

## Stringman
Four motors reach a whole room: open-source cable robot, assembled for $795
Page: https://openrobotkits.com/robots/stringman/ | API: https://openrobotkits.com/api/robots/stringman.json
Type: Cable robot | Maker: Neufangled Robotics | License: Hardware CERN-OHL-W 2.0, software Apache-2.0
Build difficulty: 3 of 5 (Advanced). Print the structural parts, build two anchors and a gripper, splice wires, mount in ceiling corners; the maker calls the kit a multi-day, fairly difficult build Source: https://neufangled.com/stringman-hardware-kit
Build time: 4 to 8 hours (maker estimate for the kit). Source: https://neufangled.com/stringman-hardware-kit

Stringman is a room-scale cable robot from Neufangled Robotics. Four motors in the ceiling corners reel in lines that hang a gripper, so it can carry up to 2 kg anywhere in a room and work above clutter. The mechanical CAD, PCBs and control software are published, and it can run air gapped on your own Wi-Fi.

What it can do:
- Carry up to 2.2 kg near the floor of a room from 3 to 10 m across
- Be controlled by gamepad, LeRobot models or an MCP server
- Run air gapped on your local network, no data leaves it
