About Synthoid
Synthoid combines its SynRobot 03 humanoid platform with SaiVLA policies, a world model and the Sai Agent task system. Visual and force feedback guide multi-stage work such as fastening, assembly, inspection and material handling. The mobile dual-arm platform accepts interchangeable end tools, while its software uses task decomposition and image feedback to adapt actions during execution.
The Shanghai company demonstrated screw-fastening and PCB assembly at CIIF 2026. These demonstrations included contact correction, local replanning and coordinated use of both arms. Its commercial interface offers demonstrations and technical engagement; published performance figures are company specifications and test claims, without disclosed customer fleet or shipment totals.

Research
- Synthoid publishes SaiVLA-0 tripartite VLA architecture
2026-03-09 - Research Publication - LIBERO mean success was about 99% in preliminary simulation tests. The matched cached-feature experiment used 4.5 hours of training, compared with 7.5 hours for the baseline. The implementation is licensed Apache-2.0; task-specific model files require manual access approval on Hugging Face.

Events
- 2026-10-12 - Demonstration - Synthoid demonstrates SynRobot 03 industrial assembly at CIIF
The screw-fastening sequence combines identification, force-guided alignment, clamping, tool use and quality checks. During PCB insertion, the robot withdraws and replans around contact or alignment errors before closing the enclosure with both arms. SynRobot 03 combines a mobile base, dual arms and interchangeable end tools; performance specifications remain company-reported.
