Google DeepMind says its Gemini Robotics 2.5 model helped Apptronik’s Apollo 2 humanoid pick and pack automotive parts with a 96% success rate in a Mercedes-Benz production-line proof of concept. The result puts a concrete factory task behind the model’s pitch for more capable, dexterous robots, though it is not evidence of routine production deployment.

What happened

Google DeepMind introduced Gemini Robotics 2.5 as its most capable vision-language-action model to date, focused on robot dexterity, reliability and safety. The company says the model was used in the Mercedes-Benz trial, where Apollo 2 handled automotive parts.

The announcement also highlights inference-time reasoning guidance intended to help robots avoid hazards. Google DeepMind says development was accelerated using its Gemini 4 Argon platform. Read the announcement.

Why it matters

A 96% success rate in a real-world proof of concept is a more useful signal than a robot performing a carefully staged party trick. Picking and packing parts tests whether a model can connect what it sees with actions on physical objects, where a poor grip or movement has consequences.

But a proof of concept is not a deployment record. The announcement does not establish how the trial was conducted, how many attempts it involved, or whether the result holds up across shifts, production lines and less forgiving tasks. The percentage is promising; the conditions around it matter.

Our read

This is a credible step towards robots that can do more than repeat a narrow sequence, and the factory trial gives the claim a practical anchor. The sensible verdict is promising, not job-done: the next test is whether the system can maintain its performance reliably outside a demonstration.

What to watch

  • Whether Google DeepMind or Apptronik publishes details of the trial and its evaluation method.
  • Whether Apollo 2 moves from proof of concept to sustained use on a production line.
  • How the model’s hazard-avoidance guidance performs in broader, less controlled settings.

Discussion spark: What evidence would convince you that a robot’s factory-trial success rate is ready to be treated as a production result?

Update

What changed

IoT Tech News adds that the Mercedes-Benz proof of concept ran on active production lines in Kecskemét, Hungary, and Sindelfingen, Germany. Apptronik’s Apollo 2 sorted automotive parts from bulk bins into trays in the order required for each vehicle, rather than working through a laboratory-only demonstration.

The report says two models shared the task: Gemini Robotics ER tracked the workflow, while Gemini Robotics 2.5 controlled Apollo 2’s hands and arms. The evaluation covered 200 distinct tasks.

The report also describes Gemini 4 Argon being used to generate simulation practice runs and digital twins, so engineers could examine failures before testing changes on robots. Separately, Google says Argon scored 99.5 per cent on the ASIMOV-Jailbreak benchmark for resisting disguised unsafe requests.

Update

What changed

Google DeepMind is rolling Gemini Robotics 2.5 out through robotics partners, Technobezz reports. The article says the model is intended to help robots handle a wider range of physical jobs, including using ordinary tools and manipulating fragile or bendable objects.

Technobezz also reports that Google DeepMind evaluated the model on more than 200 tasks, assessing the range and complexity of work as well as performance. That adds context to the factory-trial result already covered, though the article does not provide task-level results or evaluation details.

The company says the update includes changes intended to steer robots towards safer physical behaviour, alongside a new benchmark for resistance to adversarial jailbreaks targeting robotics systems.

Update

What changed

Firstpost reports that Google says Gemini Robotics 2.5 achieved success rates 20 to 30 per cent higher than its predecessor in laboratory testing. Google also said the model was 20 to 30 per cent faster in those tests, adding performance figures that put the existing factory-trial result in context without making them production-line measurements.

The report says Google’s ASIMOV-Jailbreak benchmark gave the system a 98.8 per cent safety score with Gemini 4 Argon in the loop, compared with 73.5 per cent for Gemini Robotics ER 2 alone. Those are Google’s benchmark results as reported by Firstpost, not independent evidence that robots will be safe in every physical setting.

Firstpost also says Argon generates variations of practice tests from real-world camera data and analyses failures to suggest improvements.
