A Chinese robotics company has published behind-the-scenes footage of its new humanoid robot. EngineAI unveiled its T800 robot just a day earlier. Still, its launch video, featuring the machine breaking down doors and delivering rapid kicks in a stylised studio, quickly fuelled doubts about its authenticity.
Despite company assurances that the clip contained “no CGI, no AI, no video speed-up,” viewers questioned the cinematic lighting, editing, and fluid motion. This scepticism reflects a growing challenge in the field of humanoid robotics. Here, increasingly lifelike movements often blur the line between engineering and visual effects.

It excels in various applications with high endurance and cost-effective operation. pic.twitter.com/pl5XwovCWO
— China Daily (@ChinaDaily) December 4, 2025In direct response, EngineAI released new footage on X titled “T800 BTS Footage: Setting the Record Straight on CGI Rumours.” The video strips away dramatic colour grading and cuts, presenting the robot in a plain studio performing the same actions. The raw clip clearly shows mechanical joints and actuator movements. The company states these are powered by 450 newton-metres of joint torque and 29 degrees of freedom.
EngineAI is not alone in facing such accusations. Earlier this month, Xpeng released additional engineering clips. This was after its Iron robot prompted speculation that a human might be inside a suit. Similarly, UBTECH Robotics faced doubts after a video surfaced of hundreds of Walker S2 robots moving in sync. This prompted them to release unedited drone footage to prove authenticity.
These disputes underscore how rapidly humanoid motion is advancing, making once-impossible movements convincing enough to trigger public scepticism.
EngineAI states its ambitions extend beyond viral demonstrations. The company plans “scenario-based verification and large-scale deployment” of the T800 in 2026. They are targeting industrial production, commercial services, and household companionship. An entertainment track is also in development, including a “Robot Boxer” event scheduled for December 24.
