INTRODUCTION If you want to make a robot at your home, let me tell you this. There are basically five types of robots. They are:- 1. LEVEL ONE ROBOT (wired robot with 2 dpdt switch). 2. LEVEL TWO ROBOT (Wireless robot with button control). 3. LEVEL THREE ROBOT (Wireless autonomous/ programmed robot). 4. LEVEL FOUR ROBOT(solar cell and panel 12v ) 5. LEVEL FIVE ROBOT(robot war fight) 6. LEVEL SIX ROBOT (Mobile Control Robot)

Tools & Components

Battery and Chasis

What Else You need… There are following tools are required for this project- 1.Soldering iron 2.Hack saw/ blade 3.Screw drivers 4.Multimeter 5.Pliers 6.Wire stripper 7.Spanner 8.Hammer

Components There are following components are required for this project- Battery (12 volt, 2 to 4 Amps) 1 nos. DPDT Switch 2nos. Ribbon wire strip 3 meters+ DC Geared Motors 4(rpm- 60,100,200) Chassis 1 Wheels 4 Soldering wire As required

Chassis Chassis is a mechanical assembly for making a 4 wheel drive platform. Where you can mount any controller board to drive your bot. Optionally you can use 4 DC geared motors and 4 wheels with rubber rings so you can make both variants.

DPDT switches using circuit HERE, A ‘+’ 12V POWER SUPPLY B ‘-‘12V POWER SUPPLY C ‘+’ 12V POWER SUPPLY D ‘-‘12V POWER SUPPLY

Motor connections

Power Supply For power supply you can either use a 12 V battery Or you can use an adapter 12 V from 2 to 4 Amps

CONTROLS Using robot control Before designing control wired we have to learn basic movement of robot which is shown in following table. Movements Motor1 (left) Motor2(right) For moving forward Clockwise Clockwise For moving backward Anticlockwise Anticlockwise For turning left Off Clockwise For turning right Clockwise Off.

The following switch positions will give you the respective movement L-DPDT switch R-DPDT switch Movement TOP TOP Forward BOTTOM BOTTOM Reverse —nil—– TOP Left TOP –nil– Right TOP BOTTOM 360 right BOTTOM TOP 360 left Thus you are ready with your first LEVEL ONE WIRED ROBOT
