Rover Design essentials

In like the idea of a mini rover, something small and light. Mobile Phone sized perhaps.

i wonder if one could let them talk to each other and help eachother somehow!

Flocking is a behaviour that is commonly found in nature. Animals sometimes flock for protection from wind or low temperatures but mainly for the protection that a flock offers from predators. When a predator attempts to attack a flock all the animals within the flock will flee for their lives, thus confusing the predator who now has to try to target one of many animals. Therefore the chance of any individual being caught and killed by a predator decreases with increasing flock size. In order to maintain a flock animals have to remain in close proximity to each other whilst changing direction and speed. The members of the flock also have to avoid collisions with each other and obstacles within their environment. Flocking behaviour can be found in birds, land animals (i.e. cows where the flock is known as a herd or sheep), and fish (where it is known as a school). Flocking presents an interesting problem in the field of robotics since it requires two opposing goals, the robots have to get close to each other but also have to avoid collisions. With many robots in close proximity, their sensors will receive more noise than when the robots are not so close together, for example false sonar echoes can be received from other robots, thus giving range errors. For these reasons flocking and the required sensor fusion formed a non-trivial task with which to test the robots.

Real time flocking was achieved reactively using a subsumption like architecture, but with a simple dynamic form of leadership. The four levels of control in this architecture are:

avoid objects (most basic behaviour with highest priority),
if no other robots are visible become a leader and wander,
if in a flock try to maintain position,
if a flock can be seen in the distance, speed up and head towards it, with more priory being given to following the closest visible leader.

mobile phones already have camera, microprocessor, battery, antenna, gps, so the only issues would be propulsion and heating. A smaller (lighter) rover needs less power and smaller wheels to navigate, so by slapping on some large (maybe 5-10 cm diameter and 5 cm wide?) and light wheels, it might be able to navigate the surface. I don't know what the heating requirements would be; electronics can be made to operate at extremely low temperatures.

A cell phone on Earth is NOT a rover on the moon in a extremely hostile evironment (vacuum, extreme temperature range, charged lunar soil). There will be many radiation, thermal, power, and communications challege. I wish you luck
