The TetraBOT T4-C wheeled humanoid developer edition supports fixed or mobile base, binocular vision, an adjustable lift structure and strong compute. Fully open-stack development reshapes the R&D threshold, so every build has a scene to land in. Price starts at RMB 23,900.
The T4-C is built for developers who need a real, modifiable humanoid platform without a six-figure budget. The wheeled base lowers stability and power barriers for indoor research, while the adjustable lift extends the working envelope for manipulation tasks.
The “fully open” pitch matters most. Robotics R&D has long been gated by closed stacks: you can run demos but not rewrite the brain. An open developer edition lets universities and startups prototype end to end, from perception to control to task logic, on one affordable body.
For the humanoid field, the constraint was never the idea but the cost of the bench. A RMB 23,900 base that ships with vision and compute lowers the entry point for the next wave of embodied-AI experiments, the same dynamic that drove cheap dev boards in earlier computing waves.
