R. Sammy destroyed by the Alphasprayer

R. Sammy destroyed by the Alphasprayer is the discovery and initial assessment of the robot’s destruction inside the New York City Police Department. The incident changes a robot’s disappearance into a crisis within the institution: R. Sammy is found irreversibly deactivated, an alphasprayer is identified as the cause, and the Commissioner concludes that the act is property damage rather than murder, even as its location threatens a first-class scandal.

Discovery and Identification

The discovery reaches Elijah Baley through R. Daneel Olivaw, who reports that there is confusion at the department because a corpse has been found there. When Baley asks who it is, Daneel identifies the errand boy, K. Sammy. Baley objects to the word corpse, prompting Daneel to clarify that the discovery is a robot with a completely deactivated brain. That exchange establishes both the immediate fact and the difference in how the two characters classify it: the robot is dead in practical terms, but Baley resists treating a machine as a human corpse.

Dr. Gerrigel explains that he found the robot after taking a wrong turn into a photographic-supply room. A brief examination showed that the prone figure was irreversibly deactivated. The room’s photographic film had been fogged, and counters detected the radiation source from ten feet away, corroborating the identification of the weapon and the circumstances of the deactivation.

The Weapon and the Cause

The decisive object is an alphasprayer, a shiny ovoid about two inches long and half an inch wide, with a mica window at one end. It is found in R. Sammy’s partly clenched right fist, pressed against the robot’s skull as though touching its head had been the machine’s last action. The placement links the object directly to the shutdown rather than leaving the cause as an inference based only on the damaged robot.

The alphasprayer emits hard radiation in one direction through its mica window. Its radiation randomized R. Sammy’s positronic brain paths, causing immediate, irreversible deactivation. The device has legitimate uses, but killing robots is not a legal one. Its presence therefore identifies the means while also making the act a matter of unauthorized weapon use. The damaged photographic film and the counters’ detection provide separate confirmation: the evidence is described as conclusive, not merely suggestive.

Access, Motive, and Legal Classification

The Commissioner regards the setting as the most troubling feature. The destruction occurred inside the police department, where the perpetrator must have been someone with access to the building; the Commissioner reasons that an outsider wanting to disable a robot could have done so more safely elsewhere. The alphasprayer was also difficult to obtain, narrowing the Commissioner’s suspicion toward someone able to acquire and handle such a device.

Daneel asks what motive could explain the act. The Commissioner points out that R. Sammy had annoyed Baley, but Baley and Daneel reject that irritation as an adequate murder motive. The discussion exposes a difference between moral description and legal category: the Commissioner insists that the act is not murder, because R. Sammy is property under the terms he invokes, and urges the others to keep their legal terminology exact.

That distinction does not make the incident inconsequential. The Commissioner says that destruction of a robot elsewhere would be treated as nothing, whereas destruction inside the department could become a major scandal. The institution’s concern is therefore not only what happened to R. Sammy, but what the event implies about security and responsibility within its own ranks.

Institutional Consequences and Significance

R. Sammy’s deactivation turns a missing or absent department robot into evidence of a deliberate act carried out with a scarce, identifiable weapon. The location points inward; the weapon requires access; and the discovery immediately prompts questions about who last saw R. Sammy. In this way, the incident becomes an investigative problem as well as a breach of departmental order.

The episode also places the human-robot distinction under pressure without resolving it through sentiment. Baley reacts strongly to Daneel’s initial description of a corpse, while the Commissioner converts the same destruction into a question of property damage and institutional scandal. Daneel’s question about motive keeps the possibility of meaningful harm in view, but the Commissioner’s legal framing limits what the department is prepared to call the offense. The event’s force lies in that tension: R. Sammy is irretrievably gone, yet the official category for the act treats the loss as damage to property.
