Very often on various forums or websites devoted to robotics
can be found such a question: how to make a robot out of scrap materials?
On such issues immediately clear that someone who gives a beginner and not
enough that the meaning of robotics.
But strangely enough from improvised materials can make a robot wit … need
only to show.
Introduction 
I asked idea to write some grandiose book or a comprehensive training course. I
just wanted to answer the questions here such newcomers. Actually, I’m not going
to play for time and immediately describe how you can make a simple robot, which
would react to the environment, but rather made the rounds of the obstacles.
Preparation
I think you understand that to create a robot need some details. Namely:
* Two of the motor 1.5 volts each
* Two SPDT switch
* Two batteries
* One case for these batteries
* One plastic ball with a through hole
* Three clips
* Little wires
Buy a can or on the radio market, or online store. In any case, you meet the
300-400 rubles.
So, you’ve got all the necessary details, and I begin to explain how and what to
do.
Step 1
We have the wiring. Cut the wires 13 to 6 cm each.
Now every wire with two ends to remove 1 cm of insulation with pliers or a
knife.
Step 2
With the soldering iron to attach two wires to the motor and three wires to the
SPDT switch.
We take kopus battery. On one side of him depart red and black wires. Therefore,
to the other side pripaevaem another wire.
Now the holder of the batteries are turning upside down and with the help of
glue Glue SPDT switches in the form of a letter V.
Step 4
Next to the body for two of our batteries Glue the motor so that they rotate
forward.
Step 5
We take a large paper clip. Unbend it. Get a wire. We take a plastic or metal
ball through a through hole and got through a former paper clip. Now Glue this
construction to the holder of batteries.
Step 6
Has come very complicated process. It is necessary to properly solder and solder
all wiring. How to do this is shown in the figure.
Step 7
To our robot to react to the world around him and was able to go around the
obstacles we will make it antenna. We take two paper clips, unbend them.
Then Glue them to the SPDT switch (better stick than solder – otherwise you can
gone through switches)
Step 8
To secure the axis of the little motor failure, we dress them in the rubber.
This can take the insulation from the wire and put it on the axle.
Step 9
So what? Here we are with you and make the first simple robot that reacts to
an obstacle and avoid them. To this robot drove insert the batteries and
naooborot. And in order to speed up or slow down the movement of the robot, then
glue the motors, as in the figure.
Conclusion
In this article we looked at creating the most rudimentary robot.
But you do not want and do not wake at this stop, right?
Therefore, I suggest you another photo report entitled "How to make a
BEAM-robot?".
Described in this book, the robot will react to light, that is to go to him or
from him.
