3.0 PROJECT COMPONENT DESCRIPTION

3.1 Manual Robot
The manual robot consists of four DC motors, controlled by the PS2 controller that

is connected to the Cytron PS2 Shield and directly stacked on top on the Arduino Mega. A

DC motor will control the movement of the mechanical hand. A servo motor is placed at the
edge of the mechanical hand to grip the Gerege.

1. DC Motor 5 Linear Motor with 15N/cm torque. Max
speed 250rpm
2. Servo Motor 1 Torque 15kg/cm
3. Arduino Mega 1 ATMega 2560 controller
4. PS2 Controller 1 Standard Sony PS2 Joystick
5. Cytron PS2 Shield 1 Interface between controller and joystick
6. Lipo ion Battery 2 11.1V 2500mah

3.2 Autonomous Robot

The autonomous robot consists of 12 servo motors and is locked in place by a series

of “U” joint brackets. The slide switch, resister, LED, stackable shield and Arduino Mega
are placed together which act at the brains of the robot. A magnetometer sends the angular

position of the robot to the Arduino.
