PICK AND PLACE ROBOT
Automatic Robotic arms are used in manufacturing industries at places where
it is hazardous for humans to work or where very fast, precise & repetitive work
needs to be done.Three motors will be used for picking up (pickup point) & placing
(drop point) the object. IR sensors will be used to detect if an object has arrived at the
pickup point, then the robotic arm will move & pick up the object & move towards
the drop point. Another IR sensor is used to check if any object is there at the drop
point if so an alarm will be sounded until the object at drop point is removed. As soon
as the object is removed, the object in the robotic arm is placed & the arm goes back
to initial position.8951/8952 microcontroller is used over here which checks the
sensor input & controls the motors. The circuit consist of three motors & their
corresponding drivers. Two IR transmitters & receivers for detecting the objects at
pickup & drop point.
