Today the self navigated mobile vehicles are used in many different
areas such as space researches for example; path finder, and
military researches for example: mine detection robots, remote
controlled mapping applications of military, in unhealthy conditions
for the human for examlple in raditional environments, and also in
some hobbies such as Sumo Robots.
In these sensor
based navigations the robot moves according to the evaluation of the
current data that is done by the microcontroller. Being limited with
the imaginary of the human brain, the robotics has infinite
applications. This limitless attracts the people to research on this
subject.
The budget reserved
for the researches on robotics differs from country to country
according to the economical factors. This sitution effects the
people who are interested in this subject badly, because the
available components for making a robot is limited with the
capaticities of the electronics markets. For example in Turkey,
there is not a place to get a ready-made robot on the contrary to
the foreign countries. In the foreign countries it is available to
find a robot in a set which is ready to build. These circumstances
can make being interesteed with robots expensive and tiresome.
To deal with all
components of a robot from its mechanical construction to its
software makes being aware of the every part of a robot. The first
step to make a robot is designing an appropriate form according to
the purpose of the research. Constructing our robot like a tank is
came out from this point of view. Its shape is like a tank because
navigating the vehicle with two seperate parts gives the advantage
of simpler kinematic equations for the wheels. If the vehicle would
be navigated by the two front wheels, lots of kinematic equations
should be solved to design the vehicle. Also making the vehicle like
a tank gives the simplicity of rotating on a point. It does not need
any extra space to rotate.
The second criteria
in shaping the form of the vehicle is the energy sources. If an
accumulator is being used in the system of the vehicle, the shape of
the accumulator effects the vehicle directly, because the
accumulator would be carried on the vehicle. The other criteria of
the accumulator that effects the vehicle design is the weight of the
accumulator, or generally the shape of the energy source.
