- 2. REVOLUTION Robots areautomatic artificial life forms that can perform useful work Fractal robot is a science that promises to revolutionize technology in a way that has never been witnessed before.
- 3. FRACTALS Fractal isanything which has substantial measure of statistical self similarity
- 4. FRACTAL ROBOTS Fractalrobot is a group of homogeneous electronic cubes controlled by an operating system They are the hardware equivalent of computer software. Cubes are embedded with the chips that control their movement Smallest expected size is b/w 1000 to 10,000 atoms wide
- 5. CONSTRUCTION Cubes areassembled from face plates bolted to a cube frame Each face plates have electrical contact pads that allow data signals to be routed from one cube to another Cubes have inductive coupling to transmit power and data signals.
- 6. Symmetrically arrangedcontact pads around four edges allows rotational symmetry. Contacts are relayed out and only transmit power .
- 7. Movement Mechanism Petalsare pushed in and out of the slot with the with the aid of a motor. They have serrated edges and so engage into the neighboring cube through 45 degree by a gear wheel running the length of the slot which slides the cubes along.
- 9. Implementation Of ComputerControl Cubes have a microcontroller to perform basic operations. The largest component of the Fractal Robot system is the software Fractal architecture dominates the functions of the core of the O.S, the data structures, the implementation of the devices etc.
- 10. Fractal O.S Playsa crucial role in making the integration of the system seamless and feasible. Uses some features to achieve these goals. 1. Transparent data communication 2. Data compression at all levels 3. Awareness of built in self repair.
- 11. Fractal Bus: AFractal bus permits Hardware and software to merge seamlessly into one unified data structure. It helps in sending and receiving fractally controlled data.
- 12. MOVEMENT ALGORITHMS theseare called as digital matter control. There are only three basic movement algorithms. · Pick and place · N-streamers · L-streamers
- 13. Pick and place Commands are issued to a collection of cubes telling each cube where to go. A command of "cube 517 move left by 2 positions" results in only one cube moving in the entire machine. Eg: When ever a shell or bomb comes the wall read just itself to dodge them
- 14. N-Streamers • A cubeis pushed out from the surface, and then another cube is moved into the vacant position.‡ • The new cube is joined to the tail of the growing rod and pushed out again to grow the rod.‡‡ • For bridge building applications, the tentacles are grown vertically to make tall posts.
- 15. L-streamers L-shape ofcubes numbered 4, 5, 6 are attached to a rod numbered 1, 2, 3 a new cube 7 is added so that the rod grows by one cube. Cubes 7&6 are moved till 5,6&7 forms an L shape
- 16. By grouping cubesand moving them, any structure can be programmed easily within minutes
- 17. Self repair: Ifa part is damaged robot rebuilds itself by shuffling the cubes around If a walking has lost its leg then robot could reconfigure its structure and resynthesize the lost features This feature helps in space applications.
- 18. Partial dismantlingof cubes and then reassembling at robot assembly station. A conveyor belt system and assembled into the whole unit by robotic assembly station Third scheme involves smaller robots servicing larger robots.
