A two-wheel balancing vehicle includes a chassis including one or more mounting interfaces configured to detachably mount one or more fighting modules for robotic competition. The two-wheel balancing vehicle also includes two wheel assemblies respectively mounted at a left side and a right side of the chassis. Each of the two wheel assemblies includes a wheel and a driving motor drivingly connected with the wheel and mounted to the chassis. The two-wheel balancing vehicle also includes an inertial measurement unit. The two-wheel balancing vehicle further includes a control system communicatively connected with the inertial measurement unit and the driving motor, the control system configured to receive sensing signals provided by the inertial measurement unit and to control a balancing state of the two-wheel balancing vehicle. The inertial measurement unit and the control system are mounted to the chassis.

A weapons platform including an undercarriage (11, 111) and a weapon (13, 113) that is positioned in a directable manner on the undercarriage (11, 111). The undercarriage (11, 111) may be supported in relation to the ground beneath by a supporting device (16, 116) that is damped in order to absorb firing recoil forces, the damping characteristics of the supporting device (16, 116) being adjustable in accordance with the firing recoil forces that are to be expected from the weapon (13, 113). The weapons platform (10, 110) may be mounted on a military vehicle (1). A method for operating such a weapons platform (10, 110) is also disclosed.

A self-propelled gun system (10) comprising a chassis (200) to which is mounted a gun barrel (300) having a gun barrel axis (302). The system also has a chassis suspension system (400) comprising a first wheel arm (402) extending away from the chassis (200) to a first wheel (404), the first wheel (404) being rotatably mounted on the first wheel arm (402), the first wheel (404) configured for engagement with, and travelling along, a support surface (500) to support the chassis (200) a distance (Dz) apart from the support surface (500). There is also provided a recoil mitigation system (900) comprising a recoil support leg (902) which extends away from the chassis (200) to a foot end (904), the foot end (904) operable to engage with the support surface (500) during firing of a projectile (340) from the gun barrel (300). The foot end (904) of the recoil support leg (902) is operable to be spaced apart from the support surface (500) when the gun system (10) is in transit. The recoil support leg (902) is configured to react against recoil force (Fr) in the z-axis from the firing of a projectile (340) from the gun barrel (300). The recoil mitigation system (900) further comprising a wheel brake control device (600) configured for applying a braking force to the chassis first wheel (404) after the firing of a projectile (340) from the gun barrel (300) and after the rotatable first wheel (404) has started rotating along the support surface (500) in response to the firing of a projectile (340) from the gun barrel (300).
