Abstract of our project
Human by his nature is very much reluctant to perform any repetitive task, so from the very beginning of
civilization we are trying to develop some sort of technology, which can give us relief from our
monotonous tasks. But with the time, our civilization becomes industry dependent and we are required to
accomplish our tasks quicker and under the less human observation. This requirement insists us to design
some machines, which can perform such tasks automatically or with a little manual operation. Basically
these machines are known as robot. But today the word ‘robot’ not only bounded to the machines used for
industrial automation, but also it covers all sorts of machines, which can be used instead of a living being.
So we can generally classify all the robots in two categories
Introduction to proposed mechanical structure of the robot
Mechanics is most elemental subject related to robotics, so our first step in this project was to
suitable mechanical structure for the robot to be born. For this reason we have
model of the fictitious robot. This model was reviewed several times with the propagation
and a final 3-D model appears in front of ultimately
us. This model is shown below
PCB and Motherboard CB Mounting
The 7805 IC and 7806 IC are used to supply the microcontroller and motors an amount of 5V dc and 6V dc
respectively. The PCB in which the ICs are mounted is required to mount with the structure of the lower
extremities of the robot. The RIVOBOT motherboard in which the microcontroller is mounted is also
required to be mounted in the structure of the robot. So it was a difficult task to mount both the PCB and
microcontroller with the structure as the mounting should not make the task of supplying the required
voltage to the motors troublesome and the wiring of the motors with the microcontroller ports should not
disturb the movement.
