Simple Wired  Robot Manual tethered by the control wired,wire 4x2 or 4x4 ! dc gear motor 300rpm-1000rpm ...racing 4x4,robot mod,robot wars fight !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) by Me

Step 1: Tools & Components

This is a primer project which covers following concepts-

    1.Power Supply.or 12v battery
    2.DPDT switch operation.
    3.DC Geared Motors

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 of the motor. Draw a rough sketch of the base you need to cut keeping in mind the placement of motors and wheels.

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

Picture of 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

Picture of What is Caster Wheel
caster-wheel-2.png.jpg

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

Picture 5.jpg
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

Picture of Motor connections
image06.jpg
level one robot circuit.png
The motors are fixed to the chassis and the tyres are fitted to the DC Geared Motors 

4x4 and 4x2 ! outdoor or indoor !! !

Step 7: Power Supply &12 battery

Picture of Power Supply &12 battery
motordrivers_clip_image009_0000.jpg
solar_panel.jpg
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

i have made chassis for my robot which is around 4kg.which motor would suitable for it?
NithyaN17 months ago
harshb2 NithyaN15 months ago

i will prefer 250 rpm motor not 300 so that the robo could climb on the slopes. more the rpm, less the thrust (important to climb on slope and push back the opponents ) :)))))

which rpm motor is bbest for robowar

i would preffer lo rpm motor (100 or 150 rpm) bcs it gives nice thrust. the robo wil be slow but it will push back athers :)))

300 rpm it would fast !
100rpm slow

60rpm very slow !

i have made chassis for my robot which is around 15-20kg.which motor would suitable for it?

would 900rpm dc geared motor be suitable!!!!!!

for roborace is 300 rpm sufficient or would there be a problem in using a higher one

i have made this robot now i want to modifies this by adding claw in it so it can pick up the things please help me with this

antelero8 months ago

Excelent!

can anyone help my level 1 robo car is not working properly now but it was working fine when i made it..the problem is that when i press right or left switch individually it works fine but when i press them both to go forward it stop i mean it will go few milimeters and then stop for a sec and then again go few milimeter and again stop like that... can anyone tell what is the problem

avdhoot i wanna make a similar robot ...can u suggest me wch motors to use n stuff related to that..?

300 rpm it would fast

DC Geared Motors 4nos 4x4 or 2 nos 4x2

what are these specifications and what is the RPM required....

Avadhut.Deshmukh (author)  akshay.aky.5010 months ago

4x4-wheel Robotic chassis is designed for indoor and outdoor operation requiring higher ground clearance and faster maneuverability.


Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or r. min−1) is a measure of the frequency of a rotation. It annotates the number of turns completed in one minute around a fixed axis. It is used as a measure of rotational speed of a mechanical component.
speed 300rpm to 1000rpm

which motor is for robo race??

12v Dc Gerard motor 300 to 1000 rpm ...

hey, how to make a wired pick and place robot manual using servo motor,, ??
