An embodiment upper body structure for a vehicle body includes a front body configured to be mounted on a front portion of an under body of the vehicle body, the front body including front side sills respectively disposed at two opposite sides thereof based on a vehicle width direction and center pillars respectively coupled to the front side sills, each of the center pillars including a quadrangular closed cross-section defined by coupling a center pillar outer member and a center pillar inner member and an outer flange portion extending in a forward/rearward direction of the vehicle body.

Provided is a system for robotic collaboration, including a first robotic chassis and a second robotic chassis each including a medium storing instructions that when executed by a respective processor effectuates operations including: capturing data of an environment and data indicative of movement; inferring locations visited up to a current location based on at least the data of the environment; and tracking areas cleaned based on the locations visited. The first robotic chassis performs a first part of a task and the second robotic chassis performs a second part of the task after the first robotic chassis completes the first part of the task.

An embodiment is a vehicle body including a vehicle body skeleton including a tail gate frame and a rear side member connected to a lower portion of the tail gate frame, a chassis frame including a longitudinal frame disposed in the length direction of the vehicle body, and a vehicle body rear connection structure configured to connect the vehicle body skeleton and the chassis frame, wherein the longitudinal frame is connected to an intersecting position of the lower portion of the tail gate frame and the rear side member.

A movable object includes: a steering part including a wheel provided to rotate along a ground, a wheel rod connected to the wheel and extending in a direction away from the wheel, and a steering motor connected to the wheel rod to rotate the wheel rod and steer the wheel; and a cover part disposed on top of the steering part, and including a receiving member in which a portion of the steering part is received. When the steering motor rotates the wheel rod in one direction, the steering part is engaged with the receiving member so that the steering part and the cover part may be joined, and when the steering motor rotates the wheel rod in an opposite direction, the steering part is separated from the receiving member so that the steering part and the cover part may be disengaged.

A multipurpose vehicle system with interchangeable operational components and power supplies is operational in multiple operational modes. The operational modes include: a personal transport vehicle mode, a service vehicle mode, and a commercial vehicle mode. The vehicle system has a dimensionally adjustable chassis module. The chassis module has the capacity to detachably attach to multiple exterior, interior, motor, and transmission components. The chassis module supports a cabin module and a rear module that enables formation of different iterations of vehicles. The vehicle system provides multiple different and interchangeable power supplies, like a rechargeable battery and a hydrogen tank. The power supplies are interchangeable. The used components can be recycled and interchanged with new components. The vehicle system also comprises at least one autonomous trailer that comprises a receiver in communication with a transmitter in the chassis module, allowing the autonomous trailer to be remotely towed by the chassis module.

A military vehicle includes a passenger capsule, a front module coupled to a front end of the passenger capsule, a rear module coupled to a rear end of the passenger capsule, a front axle coupled to the front module, a rear axle coupled to the rear module, an engine coupled by the front module, a front differential coupled to the front axle, a transaxle, and an actuator. The transaxle is coupled to the engine, the rear axle, and the front differential. The transaxle includes an internal mechanical disconnect that facilitates decoupling the transaxle from the front differential. The actuator is accessible from an exterior of the passenger capsule to engage the internal mechanical disconnect.

The disclosed technology regards a de-coupled V-hull structure for use with an armored vehicle, and energy absorbing crush elements suitable for mounting the V-hull structure in a de-coupled manner to the vehicle. The energy absorbing V-hull structure includes a sloped armor structure forming a cavity having a v-shaped cross-section and a plurality of reinforcing elements, including a backbone, hull stiffeners and lateral supports. The elements are coupled together and supported by energy absorber mounts, extending along each side of the structure. Crush elements suitable for decoupling the V-hull structure are also disclosed, having a uniquely designed housing, a plurality of plates positioned within the housing, and affixation means for securing the crush element to the underside of the vehicle and to the top of the V-hull structure.

A vehicle undercover mounting bracket for mounting an undercover body is provided. The vehicle undercover mounting bracket includes a frame-side mounting portion mounted on a side rail of a truck frame, an undercover-side mounting portion mounted on the undercover body and spaced apart from the frame-side mounting portion in a longitudinal direction of the side rail, and a connecting portion which extends in the longitudinal direction of the side rail and connects the frame-side mounting portion and the undercover-side mounting portion.

A mounting assembly is configured to join a vehicle body to a vehicle chassis with a bolt. The mounting assembly includes an outer tube and an inner sleeve. The outer tube defines a sleeve channel, and is configured to be fixed to one of the vehicle chassis and the vehicle body. The inner sleeve is disposed within the sleeve channel of the outer tube, and defines a bolt hole configured to receive the bolt. The outer tube, the inner sleeve, and the bolt cooperate to join the vehicle body to the vehicle chassis. An initiation slot is defined in the outer tube, such that the sleeve channel is an incomplete cylindrical shell.
