Industrial Applications
ROBAN 2 is a mid-size teaching and research family. Its four editions have 23, 25 or 45 total DOF and different perception hardware. Current manuals identify revision 2.2, 39±4 kg, while the IPO filing’s older family description says about 42 kg. Neither mass nor 45 DOF should be universal.
This editorial assessment concerns industrial buyer readiness. It is not an independent performance test.

Manipulation and Perception
23-joint body:2 head, 8 arms, 1 waist, 12 legs. Passive hands 23 total; gripper pair adds 2→25; Revo2 hands add 22→45, including passive joints. Current manual endpoint load≥1 kg is a lower bound, not a verified maximum. Hand component 20 kg load claim is not robot arm capacity.
Smart lacks camera/lidar/Orin/navigation; Advanced A/B/C add depth, lidar and 117-TOPS Orin NX. RK3588 on all. Manufacturer general visual navigation claims require exact edition.
SDK and Integration
Current Roban 2.2 uses a C++17 DDS SDK; educational Python tools are separate.
| API type | Current Roban 2.2 C++17 API over Cyclone DDS |
|---|---|
| Languages | C++17 SDK, Python educational tools, Graphical programming |
| ROS support | Current SDK expressly does not use ROS1, catkin or rosbridge. Hand-component ROS support is separate. |
| Simulation | MuJoCo with Lejulab_ARM; prebuilt binaries require matching Linux architecture and robot version17. |
| Offline operation | Local DDS and MuJoCo documented; speech/model service offline scope unknown. |
| Teleoperation | Controller and version-matched VR API; VR hardware may be optional. |
| Software updates | Versioned developer package; release access, firmware and long-term update entitlement require confirmation. |
| Documentation | Open documentation |
| Integration constraints | Use actual motor names/order and robot version. SDK public headers do not include verified camera/lidar or legacy speech/FK/IK APIs. Secure local test area and operator required. |
Safety Notes
No exact-model conformity dossier or certified collaborative operating envelope verified. Emergency-stop hardware and manufacturer demonstrations do not establish safe unrestricted shared work. Roban manual requires lifting support during enabling and local supervision; powered-down joints unlock.
Compliance and Certificates
| Standard | Status | Jurisdiction | Evidence |
|---|---|---|---|
| CE marking | Unknown | European Union | No exact-model signed declaration or test evidence inspected. Generic standard references and distributor promises are not model certification. |
| ISO 10218 review required | Unknown | International | No exact-model signed declaration or test evidence inspected. Generic standard references and distributor promises are not model certification. |
Commercial Readiness
| Pricing | No current exact-edition price verified; request a configuration-specific quote. Historical family average selling prices are not a unit list price. |
|---|---|
| Price range | Quote-based or unverified |
| Lead time | Needs verification |
| Availability regions | China; present quotation required, Europe: distributor-stated Leju range, exact edition subject to quote |
| Spare parts | Distributor claims European batteries/common spares; exact Leju model inventory and replenishment lead time not independently verified. |
| Warranty | No uniform manufacturer warranty duration, exclusions or cross-border repair cost established for these models. Obtain edition-specific written terms. |
| Configuration and pricing basis | Exact configuration quotation required |
| Distributors and service | Robot Distribution advertises Leju supply, European service and training; no per-edition authorisation or stock verification. |
No price, stock or lead time inferred from generic family offers.

European Commission · Accessed Nov 2, 2026
Current Commission overview opened November 2, 2026: Machinery Directive and Regulation 2023/1230 transition; overview gives January 20, 2027 mandatory application of the Regulation. General context, not a model declaration or legal determination for a specific installation. EUR-Lex pages returned a verification challenge, so this readable primary Commission overview is cited instead.
