Starting With Robotics (Arduino)





Introduction: Starting With Robotics (Arduino)

Starting with robotics can be hard, if you don’t know where and how to start. Best way to start is to make mobile robot. In this step-by-step we will show you, how to make cheap robot with parts available in your local store and household.

Before you start you should make some plans how platform should look like. We did some sketches how robot should look like. Later we made some modifications so everything fit in properly.

I made this robot with my good friend purgec. ( )

Step 1: Tools and Parts

- board
- breadboard
- arduino (any one you like, we used mega)
- motors
- fasteners
- Velcro fasteners (hook-and-loop)
- screws (for making holes in board)
- knife
- tape

Step 2: Markup

You should start with marking up where everything should be. We did realized, that breadboard is little to big so we modified sketches to fit breadboard on base. Because of that motors must be mounted little bit back then in sketch.

Step 3: Breadboard

We mounted breadboard with Velcro fasteners. This step is one off the easiest. We used fasteners with glue on back side. We just have to cut them down and stick it to base board and breadboard.
In late steps we realized, that we did that too early because fasteners can got messy from making holes.

Step 4: Motors

We used modified hobby servo motors. How to modify a servo:
For mounting servo motors we cut holes in base board. After debate how to do it (drill can destroy this kind of board) we cut holes with two screws, smaller and sharper for making holes and bigger to make holes bigger.
For mounting motors in position we used fasteners. Fasteners were cheap, but where to short so we improvise. After this step robot was nearly finished

Step 5: Wheels and Support

In none of the steps before we didn’t think what we shall use as wheels for our robot. So we improvise again. We used two caps for canning jars and latex household gloves. We glued it to mounts with hot glue. Mount are not in center of caps. We didn’t mind that.
When wheels were mounted to motors, we realized that the vehicle is pretty high. On the back of robot will be a lot of weight so we had to make some a support. Because weight is in back (battery, arduino), there is no need to add any support in front.

Step 6: Arduino Mega

Mounting arduino is as easy as mounting breadboard. We used smaller pieces of Velcro fasteners on arduino board and bigger one on base board. Main reason of smaller pieces is that they are not in the way if you use arduino in another project.

Step 7: Battery

Currently we are using 9V battery. First we had to solder on connector to battery cable. When it was time to mount battery on base board we realized, that there is so little space. So in the rear part of base is a little unbalanced because battery is mounted on one side and there is no weight on other side.

Step 8: Test

We wrote test program using motor shield manufactures library. You can find it here:

Test program is also from the link above. We just modified it to contain what we needed.

Step 9: Improvements

There is some space to improvements. Especially with the support. It worked out well but it is not very endurable.

We wanted to show you, how to start with robotics on cheap. The bigger expenses were arduino, motor shield and motors, around 30-40 $. Other parts can be found in household so the end platform is cheap.

If tou use how can be coneccted the oin and the rest please

Hi, I really like the project but it seems the page with the code no longer exists :(. Can you please post the code or send it to me, please.

ALso what do you use to control the robot?

Add me on skype if you wish for further instructions: daniel.smith6394

I am new to this but your project was pretty simple to understand, at least the hardware part. Can you please send me the code for this project

Hello sir I have just started with electronics and don't have much idea about it can you please help me to choose which books to read to get about arduino programming

I don't know about books, but I do know that the best way to start is using Arduino's examples and reference page.



If you are new to programming, try to learn basics of C programming language.

If you want to know more about electronics, you can find some great tutorials on instructable, like this one:
