POLYBOT

Nowadays robots are increasingly used in many areas. PolyBot is a modular reconfigurable robot which is composed of modules that can be disconnected and reconnected in different arrangements to form a new configuration enabling new functionalities. It is able to change from one form to another with no external mechanical assistance .As well as enabling versatility, the massively redundant nature of the system can lead to robustness and even self-repair. An additional advantage is that economies of scale and batch fabrication of many identical modules may eventually lead to low cost .PolyBot has mainly three versions, G1, G2 and G3. The first generation of PolyBot, G1, has the basic ideas shared in all the generations of repeated modules which are built up from simple hobby RC servos, power and computation are supplied off board. The second generation of PolyBot, G2 includes onboard computing as well as the ability to reconfigure automatically via shape memory alloy actuated latches. The third generation, G3, is the most advanced one and consists of integrated active brake, more sensors than G2, low power requirement, less weight &volume and many more. Its applications include space exploration, military operations, surface mobility, underground mining and so on. PolyBot is reliable, versatile and robust. Since it is made up of repeated modules, losing one part will not affect its functionality. Mass production of these modules can reduce the cost of PolyBot.
