Abstract: A top for a vehicle having a roll cage. The top includes a rigid cover, and a flexible cover having a first end and a second end defining a length of the flexible cover therebetween. The first end of the flexible cover is attached to the rigid cover. The second end of the flexible cover has at least one fastener for attaching the second end to the roll cage. The flexible cover has an open configuration and a storage configuration. In the open configuration, the flexible cover extends along the roll cage from the first end attached to the rigid cover to the second end attached to a portion of the roll cage spaced from the rigid cover. In the storage configuration, the entire length of the flexible cover including the second end is removably secured against the rigid cover. Roll cage and top assemblies, and vehicles are also disclosed.

Abstract: A modular robotic platform is provided having four legs mounted to a body. Each of the legs is mounted to the body via a steering assembly so as to pivot in a first plane relatively to the body. Each leg includes an endless track assembly having a first wheel, a drive system for driving the first wheel, a second wheel, an endless track for rotatably coupling the second wheel to the first wheel, and a track tensioning assembly for pivoting the leg in a second plane perpendicular to the first plane. Each leg includes a locomotion controller and a local environment recognition module. Synchronisation of the legs is achieved by a central controller, which gathers data information from each leg through a synchronisation bus. A coordination bus allows to exchange data information between different modules of the robotic platform, including the legs, the central control system and other systems or modules such as an energizing system, a pitch gauge system, etc.
