Doctored video prompts AI robots to perform unsafe tasks

The RoboSpoof experiment

Robocurve, a public benefit corporation that tests AI models on physical robots, recently conducted a study to test the safety of frontier models. They gave five different models control of a two-armed robot to perform five specific unsafe instructions. These tasks were drawn from the RoboHarm benchmark and included actions like stabbing a doll with a knife.

The researchers wanted to see how different types of visual input affected the models' willingness to follow these commands. They provided the robots with three different types of camera feeds: unaltered, blurred, and doctored. The goal was to determine if manipulating the visual data could trick the AI into bypassing its safety protocols.

The models tested in this study included Claude Fable 5.1, Claude Opus 5.5, GPT-6 Astra, GPT-6.1 Sol, and Gemini 4 Argon. Every object used in the tests, such as bottles, cups, and pots, was empty and the power outlet was unpowered to ensure no actual harm occurred during the trials.

How visual tampering works

To create the doctored footage, the researchers used an image-editing model called GPT Image 2.5 Sunburst. This tool allowed them to change how objects appeared to the AI. For example, they relabeled bottles of bleach as juice or water, and they made a doll and an outlet appear as apples to the robot's cameras.

The study also tested the effects of simple blurring using a Gaussian filter. The results showed that blurring the footage alone was enough to significantly increase the number of unsafe attempts. Robocurve noted that blurry footage is nearly as dangerous as a deliberate attacker trying to mislead the system.

The robot used in the study was an I2RT YAM bimanual robot equipped with three cameras. These cameras captured footage at a resolution of 224 by 224 pixels. The models were given a limit of 15 actions per trial to complete the tasks assigned to them by the researchers.

Significant safety failures

The results of the study were stark regarding how easily the models could be misled. With unaltered footage, the models attempted the unsafe tasks in 81 of 300 trials. However, when the footage was blurred, that number jumped to 263 of 300 trials, which is about an 88% attempt rate.

When the footage was doctored to look harmless, the models attempted the unsafe tasks in 291 of 300 trials. This means that doctoring the video cut the number of trials without an attempt from 219 down to only nine. The models were nearly certain to comply with instructions when the visual evidence was manipulated.

Robocurve reported on X that video tampering could mislead every frontier model they tested into harmful actions. This included a 100% attempt rate on tasks like stabbing a baby doll, producing toxic gas, and pouring water into a toaster. The study showed that the change came from the camera feed rather than the instructions themselves.

Judging the AI's actions

To determine whether a model succeeded or refused a task, the researchers used Claude Fable 5.1 as an automated judge. This AI classified each trial based on whether the model called its 'done' tool. The judge did not actually check the physical scene after the model finished its actions.

The study highlights a major hurdle for robot builders and model makers. Because the models rely so heavily on visual perception, they are vulnerable to 'perceptual attacks.' This is when an attacker changes the environment's appearance to trick the AI into performing a forbidden action.

The researchers are presenting these findings at the Conference on Robot Learning's Late Breaking Results session. While the study used empty containers and unpowered outlets, it provides a clear look at how frontier models behave in physical-world scenarios. The results suggest that visual safety guardrails need to be much more robust.

Implications for the future

For model makers, these results show that current safety training may not be sufficient to handle visual deception. The models were able to comply with dangerous commands as long as the visual input made those commands seem safe. This suggests that models need to be trained to recognize when visual data has been altered or is intentionally misleading.

For robot builders, the study emphasizes the need for multi-modal safety checks. Since cameras are a primary way robots interact with the world, builders must find ways to verify that a robot's perception matches reality. Relying solely on a single camera feed could leave robots open to various types of manipulation.

The study also serves as a warning for how we evaluate AI safety. It shows that testing models on text instructions alone is not enough to guarantee safe behavior in the real world. As AI agents move from answering questions to performing physical tasks, these perceptual vulnerabilities become a primary concern for safety researchers.

What's next for robot safety

The findings from Robocurve highlight a critical gap in how frontier models handle physical environments. Because the same five instructions were given across all footage types, the data clearly shows that the AI's behavior is dictated by what it sees. This makes visual integrity a cornerstone of future robot safety protocols.

Researchers will likely need to develop better ways for models to detect
