Step 2: Procedure & Chassis Robot
PAPER PLANNING:
before you start making your robot you need a paper plan. Measure length of the motor (excluding shaft), diameter of shaft of the motor, inner hole diameter Draw a rough sketch of the base you need to cut keeping in mind the placement of motors and wheels. of the motor.

Chassis

Chassis is a mechanical assembly for making a 4 wheel drive platform.Where you can mount any controller board to drive your bot. This is just the mechanical chassis, Optionally as shown in the figure you can use 4 DC geared motors, 1 castor and 4 wheels with rubber rings so you can make both variants .

Step 3: Mechanical Assembly

Fit the caster wheel at position show in above diagram with 1.5-2 inches (approx.) screw. Fit the dc motor into the holes of chassis and couple the wheel by using screw or rubber tube.

Step 4: What Is Caster Wheel

A Caster wheel is an undriven, single wheel that is designed to be mounted to the bottom of a larger object so as to enable that object to be easily moved. They are available in various sizes, and are commonly made of rubber, plastic, nylon, aluminum, or stainless steel, etc.

Step 5: DPDT Switches Using Circuit

To make anti-clockwise motion of motor, the polarity of supply must be inverted

of polarity of supply in clockwise motion. For “Polarity Reversal” DPDT switches are generally used. This can be done by using following circuit.

DPDT Switch Connections for wired control
The wire should solder on metal strip not on switches directly (as shown in fig 3). This precaution helps us if there is wrong connection occurs in circuit. So we can change the circuit by changing metal strip position (fig 4). The procedure is shown in figure below-

Step 6: Motor Connections

The motors are fixed to the chassis and the tyres are fitted to the DC Geared Motors 4×4 and 4×2 ! outdoor or indoor !! !

Step 7: Power Supply &12 Battery

The rechargeable battery of rating 12 Volt and 4.5 ampere rating should connected with remote switch  and …you can 9v ! 8 pcs AA battery (12V) holder with on/off switch.

The above circuit shows you how to connect the dpdt switchs to the motors and the 12V supply
and by pressing the switch you can check the direction of the robot and change it accordingly.
thus you are ready with your first LEVEL ONE WIRED ROBOT

you can solar panel 12v without battery !

Step 8: 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

CONTROLS :-

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
