What is the intelligent anyway; could we categories how the bees building their tiny hexagonal compound nest, ants searching for their food or birds migration using precision navigation over continental are the intelligent acts; or we as the human being with our cultures and civilizations is the only one that can be categories as the intelligent being?

These kinds of question probably will not have satisfied answer as the answer is more philosophy terms rather than physics or mathematics law; therefore I think anyone could give their own opinion to this question. One of the important things is the DC motor polarity because the polarity will effect the DC motor rotate direction, you should experiment with it or you could simply change the logic truth table shown above to reflect your DC motor condition.

These switches arms is extended by using the modified paper clip so its look like animal whisker which actually used by many animals to sense its surrounding. Normally for mobile robot this bump switch is use as the last defense again the obstacles detection, most modern mobile robot also equipped with proximately sensors to sense the obstacle far before the robot bump to the object; later on this tutorial we will put this sophisticated sensor on BRAM.

Using a simple bang-bang close loop control with the hysteresis, BRAM could navigate smoothly toward the light source; for more information about using bang-bang close loop control please refer to my previous posted blog Basic Servo Motor Controlling with Microchip PIC Microcontroller.

BRAM Brain Now come to the most interesting part, as Mobile robot research paper will give BRAM an artificial life, so it behave like moth that interest is light photovore but if the light is to bright than it run from it light avoidance and when the light intensity is not bright enough than BRAM will start to explore the room searching for light and use its whisker to avoid the obstacle.

For autonomous mobile robot the world modeling is become very complex and almost impossible to put all the unpredictable and dynamically change environment inside this model; for example your cat suddenly chasing your robot, how we could plan to avoid such an action or your robot suddenly bump to the bone that your dogs just bring it from outside.

The solution for this situation is to use bottom up approach on the contrary of top down approach used in classic artificial intelligentthis method is usually called behavior based artificial intelligent. First introduced in by Rodney A. As shown by the diagram above; BRAM has four basic behaviors and each of these behaviors is given a fixed priority start from the higher obstacle avoidance: The priority selector is the algorithm method which guarantees that only one behavior could take control to the BRAM motor at a time; this priority selector work as a switch that connects the behavior action directly to the BRAM motor control.

For example if the light follower detect the light at the same time the whisker bump to the obstacle, then the priority selector will ensure that the obstacle avoidance should be served first because it has a higher priority over the light follower behavior.

For the purpose of this tutorial and to keep the program simple, BRAM implement the priority selector using just a fixed sequence call to these behavior functions, later on the BRAM final program we will fully implement this algorithm.

If the light intensity more then minimum threshold; BRAM will start to use the light following behavior to steer the motor toward the light source.

SPBRG registers pair value could be calculated: The zero error rates could be achieved by clocking the PIC16F microcontroller with external crystal at Actual Rate will be Sharp GP2D Distance Measuring Sensor The Sharp GP2D sensor is consider the primer IR infra red proximately sensor, this sensor use the triangulation method to calculate the object distance which is more immune to the ambient light condition compared to other IR proximately sensor method.

The IR pulse first is transmitted through the IR light emitter you could easily find the emitter by using your phone or digital camera to capture the IR light and when it bounces back by the object to the light receiver; the circuit inside the GP2D will start to calculate the angle between the emitting IR light and the receiving IR light and convert it to the corresponding voltage output level please refer to the sharp GP2D datasheet.

The closer the object the bigger the angle and this also produce the bigger voltage output through the sharp GP2D Vo pin and vise versa. Because BRAM is move both to the left and right, for proper alignment according to the sharp GP2D datasheet you should place the GP2D sensor vertical towards the moving object as shown on this picture bellow taken from sharp GP2D datasheet.

In order to make the program more structured and easy to be modified for the new behavior in the future, in this final program, BRAM fully implement the program fixed priority selector and each of BRAM behavior will have their own unique control over BRAM steer, speed and head light.Free research papers and projects on robotics.

Robotics is the study of robot A robot is a mechanical intelligent agent which can perform tasks on its own, or with guidance. In practice a robot is usually an electro-mechanical machine which is guided by computer and electronic programming.
