3 Axis Pick and Place Robot

Project Cost: 11,500

Project Code: 1220

Description of the project:

This 3 Axis Pick and Place Robot project is also called a Pick and Drop robot since it has a pick-and-drop robotic arm.

Operating Modes: This project is available in 4 operating modes

1. Keypad controlled (wired control)
2. Mobile operated using DTMF controlling (wireless control through mobile calling)
3. Android mobile controlled using Bluetooth Technology (wireless control)
4. PC-operated (wired or wireless, both options are available)

Mechanical Design of the Robot:

This pick-and-place robot has three main mechanical parts/components:

1. Robotic arm to hold and release the object
2. Lead screw assembly to move the arm up and down
3. The chassis of the Robot with wheels to move forward, reverse, left, and right

Dimensions of the Robot:

• Robot chassis base – 25 cm by 25 cm
• Vertical lead screw assembly – 18 cm
• Arm length – 30 cm
• Pick and place gripper length – 15 cm

Please note that these sizes may vary depending upon the modifications done in order to increase performance or reduce the weight of the Robot. If you need any specific dimensions then please email us or call us.

A detailed description of the 3 Axis Pick and Place Robot:

Operation of the Robot:

1. Initially, Robot is at a rest position, i.e. state when all motors are stopped and no object is picked or placed.
2. Once the power supply is turned on, the microcontroller will wait for a signal from the DTMF decoder which is connected to a mobile phone.
3. A User can send various instructions to the robot by dialing a call to the mobile phone which is connected to Robot.
4. When the microcontroller gets a signal to pick the object, it moves the gripper motor in say clockwise direction for a fixed time
5. When a user gives a command to move the arm in the Up direction then a vertical motor moves in a clockwise direction due to which the whole arm moves towards or away from the picking an object.
6. Once user realizes that object is picked then he/she can give command to close the grip. Then gripper motor stops to hold the object by closing jaw
7. User can give command to move arm in UP direction and now vertical motor is started in say clockwise direction. This motor also, is on for particular fixed time instant.
8. Now user can give command to move the Robot in forward or reverse direction. Depending on command wheel motor is moved in forward or opposite (here anticlockwise) direction till the time it reaches the placing platform.
9. As it reaches placing platform, user can give command sequence to release object the motor M1 stops and M2 is switched ON in opposite (here anticlockwise) direction till it releases object properly on desired place.

DC Motors and Motor Driver:

We have used 5 DC motors in this project. Motor driver IC is used because the microcontroller is not able to drive DC motors directly. So output signal of the microcontroller is given to Motor Driver ICs and the output of the driver is given to DC motors.

Applications and Advantages of 3 Axis Pick and Place Robot:

1. It can be used in the Production industry.
2. In mass production.
3. In Automobile Industry.

Future Development:

1. Bottle filling Plant.
2. Construction works.

Questions and answers about this project:

Question: Can we provide stepper motors instead of DC motors? what is the advantage of using a stepper motor?

Answer: No, we can not provide stepper motor. Reason behind this is, stepper motor has very less torque (and force is proportional to the torque) Since we need high power / force to drive the robot, like gripper, up down motion, we need high torque motors. DC motor provides the necessary torque.

Question: How you are going to send the project through courier in assembled mode or disassembled?

Answer : It is not possible to send in assembled mode. So we will disassemble it and then send by courier.

Question: Can we operate this project using mobile but without calling?

Answer : Yes you can do it by directly pressing the keys which is a wired control or by using a bluetooth device which will be a wireless control.
