Soldiers are spread swiftly across large area in lightweight round vehicles.
Inspiration from Nature
Branches of Salsola Kali turn and twist in themselves which distributes weight of the tumbleweed uniformly. This helps tumbleweed disperse seeds over large area.
One of the biggest military challenges in a dessert-like (hostile) environment is fast mobility of individual troops. Wherever they cannot be airdropped they must be transported in heavily armored vehicles, which slows down logistics. Furthermore, they are put together in the same vehicle which is a risk. A lightweight military vehicle needs to be designed for individual troops. The vehicle should be easily maneuverable and equipped with enough firepower to execute a fast surgical strike.
When one designs for the forces of nature instead of opposing them, one can no longer discard the importance of context. From lizards to camels, organisms of dessert demonstrate a range of locomotive strategies. In order to move fast, either we find strong muscle force that generates a massive thrust (such as the attack of black cobra) or we find fragility and weightless-ness of organism in a context of forces (such as dandelion). The problem at hand however, requires control over navigation. And the most suitable solution is found in a type of tumbleweed called Russian thistle (Salsola Kali). Its thin branches twine and twist in themselves, distributing the load uniformly. And its lightweight structure gets rolled over by wind. Since this strategy embraces just enough force from its context (wind) that the force does not alter structural integrity of the tumble weed, it is a perfect case for our vehicle.
Round spherical robots and tumbleweed structures have been designed for purposes ranging from art and entertainment to space and military. A number of concepts have given input to this nature gadget including Tumbleweed Survival Pod for Antartica, NASA Mars Tumbleweed Robotic Rover, Seed Planting Tumbleweed Robot and even Inflated Sphere Robot (for structural integrity). The intended vehicle would need layers of revolving spheres separated by micro ball-bearings. The vehicle must have a mechanism for navigation.
A lightweight spherical military vehicle is designed which can roll over a surface with lightening speed. There are two spheres (1, 3), one rolling over the other and both layers are separated by micro ball-bearings (25). The inner sphere accommodates a soldier- who can take over navigation manually (6, 13) and is equipped with a foldable exoskeletal gun (48) attached to his/her seat (5). This sphere has all its backend systems (8) situated at the bottom so that weight of the systems exert constant downward force which keeps the inside stable and horizontal. The outer sphere revolves about the inner sphere and is constructed with chain wheel technology (34) which will soon be used for roving missions on Mars.
