DESIGNING SIMPLE WIRED ROBOT : Ultimate EC
1. Introduction-
This is a primer project which covers following concepts-
This is a primer project which covers following concepts-
·
Power Supply.
·
DPDT switch operation.
·
D.C. Motor.
·
Basic motion of Robot
2. Tools & Components –
There are following tools are required for this project-
·
Soldering iron
·
Hack saw/ blade
·
Screw drivers
·
Multimeter
·
Pliers
·
Wire stripper
·
Spanner
·
Hammer
There are following components are required for this project-
·
Battery (6 volt , 4.5 Ah) - 1 nos.
·
DPDT Switch- 2nos.
·
Ribbon wire strip- 3 meters+
·
D.C. motor- 2nos
·
Chassis(having holes for motor) - 1
·
Remote box 1
·
Metal strip 12
·
Wheels 2 nos.
·
Castor wheel 1nos
·
Soldering wire - as required
3. Procedure-
1.
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.

2. 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.
Bolt is to fit outside of chassis
Coupling motors and wheels
3. Remote Designing-
Before designing
remote we have to learn basic movement of
robot which is shown in following
table.
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 REMOTE
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-
 DPDT Connections
4. Motor connections-
There are 4
output wires from remote which is to solder on motor by ribbon
wire strip.
Switch1's output should connect motor1 and switch 2's
on motor2. This means
switch1 controls motor 1 and switch 2 controls
motor2. Before connecting motor
by soldering, the polarity of motor
should be check buy giving direct
supplyfrom battery.
5. Power Supply-
The rechargeable battery of rating 9 Volt and 4.5 ampere rating should
connected with remote switch (as shown in fig).
4. Speed calculation of robot- Speed of robot can be calculate by following formula- Velocity = circumference * rpm Velocity = diameter * pi * rpm OR Velocity = 2 * radius * pi * rpm The RPM of motor will perfect match with its specification if only is
power rating of motor is provide by power supply.
