The present disclosure is directed to mobile correctional facility robots and systems and methods for coordinating mobile correctional facility robots to perform various tasks in a correctional facility. The mobile correctional facility robots can be used to perform many of the tasks traditionally assigned to correctional facility guards to help reduce the number of guards needed in any given correctional facility. When cooperation is employed among multiple mobile correctional facility robots to execute tasks, a central controller can be used to coordinate the efforts of the multiple robots to improve the performance of the overall system of robots as compared to the performance of the robots when working in uncoordinated effort to execute the tasks.

A gas powered fluid gun for propelling a stream or slug of a fluid at high velocity toward a target. Recoil mitigation is provided by a cavitating venturi that reduces or eliminates the associated recoil forces, with minimal or no backwash. By launching a quantity of water in the opposite direction, net momentum forces are reduced or eliminated.

A non-injurious incapacitating device is provided that includes an exterior layer defining a contained volume. A primary effect is contained within the device that deploys to size at least 10 times that of the contained volume. A power supply and a sensor are provided. The sensor communicates a contact or proximity signal when the exterior layer contacts or is within an effective range of a target. A control circuit interconnects provides a triggering signal to the primary effect based on the contact or proximity signal. The device is provided in some embodiments as a system inclusive of a launcher. A method of non-injuriously incapacitating of a target individual is also provided in which a user directs a device into proximity of the target individual. The device deploys an expansive primary effect to non-injuriously incapacitate the target individual.
