An article manufactured in a mould and which comprises a structural composite of plastics layers, the article having a wall defining an internal space for holding contents therein; wherein, the wall is formed from at least two layers of plastics materials; wherein a first of said layers comprises a thermoplastics material and at least a second layer comprises a thermosetting resin and a fibrous layer.

A door and locking system for a rear opening of a long bed trailer, the rear opening having a top edge, a bottom edge and first and second side edges, the door and locking system has a canvas door configured for mounting adjacent to the rear opening of the long bed trailer. The canvas door can move between a closed position in which the canvas door moves to close the rear opening and an open position in which the canvas door moves to open the rear opening. A locking system secured to the edges of the rear opening can move between a locked position, in which the locking system is in locking engagement with the canvas door in the closed position to secure the canvas door against the edges of the rear opening to close the opening for retaining fluidizable product in the long bed trailer and an unlocked position, in which the locking system is free from locking engagement with the canvas door to allow the canvas door to move into the open position.

A container including a first panel with a first edge having a first protrusion with a first contoured profile with at least one projection, a second panel with a second edge having a second protrusion with a second contoured profile with at least one projection, and a spline with a first channel that defines a recess with an interior profile, and a second channel separate from the first channel that defines a recess with an interior profile. The first and second channels receive the first and second protrusions, respectively, such that the first contoured profile is complementary to a portion of the interior profile and the second contoured profile is complementary to a portion of the interior profile. The first and second panel include a mid-section extending from the first and second edges, respectively. The first and second edges have a greater thickness than the thickness of the mid-sections.

A modular mobility base for a modular autonomous bot apparatus transporting an item being shipped including a mobile base platform, a component alignment interface, a mobility controller, a propulsion and steering system, and sensors. The component alignment interface provides an alignment channel into which another modular component can be placed and secured on the platform. The mobility controller generates propulsion control signals for controlling speed of the modular mobility base and steering control signals for navigation of the modular mobility base. The propulsion system is connected to the platform and responsive to the propulsion control signal. The steering system is connected to the mobile base platform and is responsive to the steering control signal to cause changes to directional movement of the modular mobility base. The sensors are disposed on the platform provide feedback sensor data to the mobility controller about a condition of the modular mobility base.

A detachable modular mobile autonomy module (MAM) for a modular autonomous bot apparatus includes a housing with latching points, an autonomous controller, location circuitry, external sensors monitoring an environment external to the MAM and providing sensor data to the controller, multi-element light panels on the housing driven by the controller; and a modular component power and data bus. The bus has a bottom side modular component electronics interface disposed on the housing that mates to a corresponding interface on another proximately-attached modular component of the bot. The MAM receives sensor data from the external sensors, receives outside sensor data from additional sensors disposed on a mobility unit of the bot, generates steering and propulsion control output signals based on location data from the location circuitry, external sensor data, mobility unit sensor data, and destination information data maintained by the controller, and generates transport and delivery information for the light panels.
