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)

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.

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 25-250 kbps. Frequency 2.4 GHz ( 16 channel) Range 100 meter.

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

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.
