Fractal robots are a revolutionary technology that could transform robotics. They consist of homogeneous electronic cubes that can move and rearrange themselves using basic algorithms. Each cube contains chips and contact pads that allow it to receive signals and power from neighboring cubes. This allows the cubes to move and assemble themselves into various structures. Potential applications include bridge building, search and rescue, medical procedures, defense, and space exploration. However, fractal robots also have limitations as the technology is still in its early stages and control software needs to be more precise.

2. REVOLUTION
 Robots are automatic 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 is anything which has substantial measure
of statistical self similarity

4. FRACTAL ROBOTS
 Fractal robot 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 are assembled 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 arranged contact pads around four edges
allows rotational symmetry.
Contacts are relayed out and only transmit power .

7. Movement Mechanism
 Petals are 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 Computer Control
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
 Plays a 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:
 A Fractal 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
these are 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 cube is 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 of cubes 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
cubes and
moving them, any
structure can be
programmed
easily within
minutes

17. Self repair:
 If a 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 dismantling of 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.
