A lot of researches studies robot arms and the ability of controlling it to track targets
which depends on the type of motors used, DC motors or servo motors. In addition to
response time that DC and motor can give as a physical structure.
Robots
consists of number of junctions built of solid materials (robot arms(
connected together by motors and the total structure lets the robot to move, these robots
can be used in places that humans cannot act inside it or in places which we need a lot of
repeated actions.
This search aimes to study the robot arm movement by controlling the motors and its
response to a drawn line using a PID controller to achive the most accuracy by using the
distrubushion constants of the camera lens which used by the robot to see. All the cameras
need to be calibrated and the constants used to move the robot in X,Y,Z.
The theoretical section presents the principle of
operation of an on-site control circuit using a DC
motor, as the continuous motor is the main element
that rotates at certain angle and thus moves the
action to the gearbox which reduces the engin
e's
rotational speed to control the variable resistance
which adjusts the voltage Vb to be equal to the
voltage Vr
The Practical section displays the results.
