Industrial Applications
ROBAN 2.2 Smart (Lingdong) is a supervised teaching/research configuration. RK3588 only, passive hands and no camera/lidar/navigation. Nominal mass 39±4 kg is not the older 42 kg family figure.
This editorial assessment concerns industrial buyer readiness. It is not an independent performance test.

Manipulation and Perception
23-joint body (2 head, 4 per arm, 1 waist, 6 per leg). Passive five-finger dummy hands; no powered gripper. Endpoint load≥1 kg lacks a maximum/reach curve, so core payload remains unknown.
RK3588, programmable LED and voice tools. No Orin, camera, lidar or autonomous navigation in this 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 | Distributor promises a supplied DoC; exact-model declaration not inspected. |
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.
