Can a household robot take the witness stand?

Two neighbours dispute who damaged a shared fence on a Tuesday night. The only witness is a humanoid household robot that stood in the garden recording video and audio all evening; its owner wants it to answer questions live, in its own words. A thought experiment, not about any real case or robot.

Side A: Let the robot answer

The robot stood there all night and saw everything. It can answer any question in seconds, from its own recording. Why make the court guess from hours of video?

Side B: Play the tape

The recording is evidence and I accept it. The robot's answers are a model's guesses, it belongs to one side, and it cannot swear an oath or face real cross-examination.

What the law says: The recording comes in; the robot is not a witness

• United States · federal courts: A witness must have personal knowledge and give evidence under oath or affirmation; a machine does neither. A recording can be admitted once someone shows it is what it claims to be, and the court can examine how it was made. Rules for machine-generated evidence are being written, with the focus on showing the system is reliable rather than letting it speak as a witness.
• England and Wales: Video and audio recordings are routinely admitted when their origin and integrity are shown, and the people who made or handled them can be questioned. Evidence is given by people under oath; a device's output is treated as a document or real evidence, not as testimony.
