4 O VERVIEW  Toys Catcher is a machine which challenges the user to capture items (stuffed toys, balls and more valuable prizes) that are placed in a wooden box.  The Player wears a special glove and moves his hand left – right, forward - backward and closes his fist in order to control wirelessly a moving shaft that ends with a gripper.

5 O VERVIEW  Our project can be used to control a group of components coordinated together to complete a specific tasks.  Various applications in real life: Clean Rooms Quarantine Environments (e.g. Chemical laboratories)

7 M ECHANICAL PART

8 X-Y Table Box. Timing Belts Pulleys Gripper Motors

9 M ECHANICAL PART  X-Y Table:  Profile 2.5cm used to build X-Y Table box with 60 X 77cm dimension.

10 M ECHANICAL PART  Timing Belts:  Control and transfer the movement between pulleys (pulley moves  belt rotate). Two Belts  Y-Axis direction One Belt  X-Axis direction.

11 M ECHANICAL PART  Pulley:  Fixes the belts that connected to motors (belt move  motor move).  Seven pulleys are used: Four Pulleys  Y-Axis direction Two Pulleys  X-Axis direction. One Pulley  Up and Down direction

12 M ECHANICAL PART  Gripper:  end of arm tooling used to catch stuffs.  Controlled by a servo motor.

13 M ECHANICAL PART  Motors:  Three Types of Motors are used: DC Motors. Servo Motor. Stepper Motor.

14 M ECHANICAL PART  Motors- DC Motors:

15 M ECHANICAL PART  Motors- DC Motors:  Responsible for the movement of gripper in X-Y axis direction.  Direction of movement controlled wirelessly.  Car motors was our choice for our project.

16 M ECHANICAL PART  Motors- DC Motors:  H-Bridge : o Reflect the direction of DC Motor motion. o Controlled wirelessly by Accelerometer (located on the glove)

17 M ECHANICAL PART  Motors- Servo Motor:

18 M ECHANICAL PART  Motors- Servo Motor:  Control open and close motion of gripper via PWM.  Flex sensor (located in the glove) control wirelessly movement of gripper.

19 M ECHANICAL PART  Motors- Stepper Motor:

20 M ECHANICAL PART  Motors- Stepper Motor:  Control up and down motion of shaft that ends with a gripper.  Flex sensor (located in the glove) control wirelessly movement of shaft.

22 S ENSORS

23  Player hand act as a main controller of all mechanical part components.  Two type of sensors are used: Flex Sensor. Accelerometer Sensor.

24 S ENSORS Accelerometer:

25 S ENSORS  Accelerometer :  ADXL335 Accelerometer Sensor is Small and thin component. low power. Complete 3-axis  Control the DC motor movement in X-Y Axis direction.

26 S ENSORS Flex Sensor:

27 S ENSORS  Flex Sensor:  Control motion of : Servo Motor ( open and close the Gripper ) Stepper Motor ( up and down the shaft that ends with gripper)  Flex bent  resistance changed  Output value changed  motion of motors changed

28 S ENSORS Wireless XBee

29 S ENSORS  Wireless XBee:  Send results of sensors (located on the glove ) to microcontroller that control the mechanical part. Transmission speed kbps. Frequency 2.4 GHz ( 16 channel) Range 100 meter.

30 C ONTENT Overview Mechanical part Sensors Controller part Conclusion

31 C ONTROLLER PART  Sender Circuit  Receiver Circuit

32 C ONTROLLER PART  Sender Circuit:

33 C ONTROLLER PART  Sender Circuit: Microcontroller Chip( PIC18F4620) Accelerometer Sensor. Flex Sensor. Wireless XBee Component. Regulator ( 9 V  5 V)

34 C ONTROLLER PART  Receiver Circuit:

35 C ONTROLLER PART  Receiver Circuit: Microcontroller Chip( PIC18F4620) H-Bridge ULN2003 Wireless XBee Component. Regulator ( 9 V  5 V)

36 C ONTROLLER PART User wear the Glove Finger Movement Shaft move down Gripper close Shaft move up hand’s movement Shaft move +ve, -ve X-Axis Left-Right Shaft move +ve, -ve Y-Axis Forward – Backward Movement Shaft move down Gripper Open Shaft move up

37 C ONTENT Overview Mechanical part Sensors Controller part Conclusion

38 C ONCLUSION  We build a system using microcontroller PIC18f4620, that can be divided into many parts: 1. Wireless part. 2. Sensor 3. Mechanical part  We apply that in a funny application, TOYS CATCHER.
