A weapon mount including a housing through which the weapon translates when fired, a conversion subsystem configured to convert translation of the weapon when fired into rotational motion, and a braking subsystem for resisting rotation of the conversion subsystem.

Weapon mount

A robot arm assembly a base unit with a shoulder assembly rotatably disposed on the base unit. A lower robot arm is pivotably attached to the shoulder assembly. An upper robot arm is pivotably attached to the lower robot arm. The base unit includes a first motor which rotates a main shaft fixed to the shoulder assembly to rotate the shoulder. A second motor in the base unit rotates a second shaft in the shoulder assembly extending through the main shaft to pivot the lower robot arm with respect to the shoulder.

Robot arm assembly

A mobile remotely controlled robot includes a robot platform and a robot arm maneuverable with respect to the robot platform. A housing is configured to be removably mounted to the robot arm. A sleeve is translatable with respect to the housing for receiving a weapon therein. There is a gear rack on the sleeve and a pinion gear, rotatably disposed in the housing, is engaged with the gear rack. A braking subsystem resists rotation of the pinion gear when the gear rack translates upon firing of the weapon.

A trailer and hitch system for a mobile robot. The trailer includes a front Ackerman steering linkage, a releasable locking mechanism for releasably positioning the Ackerman steering linkage in a turned position to arrest the trailer, a tow bar extending upwardly from the Ackerman steering linkage and terminating in a lunette ring, and spaced skid members extending downwardly and rearwardly. The mobile robot includes a hitch assembly for the lunette ring. The hitch assembly has a frame including a slot for the lunette ring and a guide portion for guiding the lunette ring into the slot, a latch pivotable with respect to the frame and biased to close the slot, and a decoupling mechanism configured to move the latch to release the lunette ring from the slot. A robot arm is maneuverable to engage the decoupling mechanism.
