This document describes a DTMF based pick and place robot project. The robot uses a PIC16F877 microcontroller and 12 relays to pick up and move an object to different locations based on DTMF codes entered from a mobile phone. The robot is able to pick up and place an object by actuating different relays according to the binary codes received from pressing numbers on the phone. Diagrams of the robot include a block diagram, schematic diagram, and multiple views of the mechanical design.

PROJECT 5: DTMF BASED PICK AND PLACE ROBOT
Description of the project
 In this project we are going to pick and place the object with
help of DTMF operation.
 We are doing this using PIC16F877.
 We are using 12 relays (R1 to R12) and DTMF kit to
functioning the robot and vehicle.
 The object has been placed in an any location with help of
DTMF functioning codes (Binary 0 and 1’s) to actuate the
robot to pick and place the object.
 The mobile phone is used to activate the DTMF with
functioning keys (1 to 9) to actuate the robot to function in
according to program.
 This process repeats again or required.
