Anchoring systems can be applied to connect a robotic system with its power supply structure (for example, umbilical cables), and then separate the same into several modules, each containing a pair of anchors. A sleeve is tensioned, by pulling the ring against its stop and, thus, performing a self-locking. The self-locking occurs because the friction force generated at the lace interface is greater than the sleeve tensioning force. In addition, the mesh is tightened by threading the stop of the ring in the house of the ring. The anchoring systems can be applied to any part of the robot and as many times as necessary, not being limited to the connection with the umbilical.

The present invention pertains to the field of the arms industry and metallurgy, and also to the fields of materials engineering and chemical engineering. More specifically, the present invention refers to a novel ammunition cartridge comprising reinforced polymer and the manufacturing process thereof. The ammunition cartridge serves for receiving the gunpowder so that explosion can occur inside the weapon barrel. The technology proposed reduces the quantity of components to be pre-manufactured and assembly processes on the product, producing a full cartridge, directly upon injecting the thermoplastic, and can also use bi-component injection. With this, the portion of the collar ring can be made entirely of fiber-reinforced polymer material, which reduces the weight of the item and is beneficial for the useful life of the weapon in the bolt region.
