Escornabot
How to build it
Isto é unha pelusa!
See that you have all the printed parts.
Check that you also have all the non-printed parts.
You won't need the USB key in this tutorial.
Grab the battery holder, the bracket and two zip-ties.
Attach the battery holder to its bracket, using the zip-ties. Take care that the zip-tie's head stays in place as in the picture.
Grab the lower platform, the ball casters, four screws, four nuts and 8 washers.
Screw one ball caster to the platform, as seen in the picture.
You should repeat previous step with the second ball caster. Ball casters are pretty jelous, and it would become upset if you didn't.
Grab the motors, their supports, 4 screws and 4 nuts.
Supports will likely have their holes slightly closed, you have to open them.
The best method is to use melting ray vision. If you don't have such a power, a small round file or any pointy tool will do.
We won't give you any clue at all about how to put the motors on the suports.
You are left on your own, we are so mercyless.
Are you still here?
If you got over previous step, screw the motors to the supports. You are likely to feel a sensation as if everything fits well. Enjoy it.
Take all the pieces that you see in the picture. You can also take a cup of coffe and some pastry.
Put the screws on the holes.
These are the only holes where the motor's supports fit.
Put the motors in the position that we show, it's no time for personal innovations.
Take these parts, and be sure that you take the 30mm (long) spacers.
There are two kinds of spacers: long ones (30mm) and short ones (28mm).
LONG
Screw the long spacers in its position, maybe you'll need to make the hole a little bigger with a small round file or anything that suits. Unless you have extremely strong and hard fingers, you will have to hold the separators with pliers.
In case you have extremely strong and hard fingers, get in touch with us, we need people like you in the project.
Get the lower platform, the battery holder with its bracket, the two short spacers, two screws and two washers.
Put the screws and its washers in place so that they fit the bracket. Check that the zip-tie's head doesn't get in the way of the spacer.
Screw the spacers leaving the bracket between them and the platborm. Use your extremely strong fingers or pliers.
Check @procastino 's astonishing hairy fingers.
Do not take this step right now. I put the wheels in this moment, because they are easier to fit, but it was awfully difficult to finish the Escornabot without taking them out again. We will carry on with this mistake and there will be wheels on the pictures, so you will have to use your mental supression powers to erase them out until the final steps.
Take the upper platform, both drivers and four screws.
Screw the drivers in their supports, be very careful because this is a quite breakable part. It can be enough with just one screw, mostly if you brake all the other supports, as I did.
If you're seeing the wheels, you're not using your mental supression powers properly!!
We're much closer to seeing somthing that resembles an Escornabot… find the lower and upper platorms, two screws and two washers.
Screw the upper platform to the spacers on front part. What's front and what's back? you're right, is difficult to explain, just look at the picture!
Now you should have something like this, a badass looking robotic platform.
Turn the Escornabot upside down.
You can take some time to tickle its belly… he will love it!
Try to wind the wires so that they stay tidy.
Wire each motor to it's side's driver.
Take the Escornabot, the keypad supports, two screws and two washers.
Screw the back of the suports in the position that you see on the picture, and notice how wise the hole that uncle @xoan designed is...
Get two screws, two nuts and two washers… We won't say where to put them, because the two red arrows will do that.
Time for brains!
Get the Arduino Pro Mini, a bunch of male-female jumpers and a 170 points breadboard.
Put the Arduino, as you see in the picture, leave four empty rows on the side of the power pins (RAW, GND, VCC) and just one empty row on the other side.
Wire the whole package according to the dazzling picture on the right, or to the humble and clear table on the next slide.
| Driver pins | Arduino pins |
Left Motor Driver | IN1 | 2 |
IN2 | 3 | |
IN3 | 4 | |
IN4 | 5 | |
- | GND | |
+ | RAW | |
Right Motor Driver | IN1 | 6 |
IN2 | 7 | |
IN3 | 8 | |
IN4 | 9 | |
- | GND | |
+ | RAW |
| Driver pins | Arduino pins |
Batteries |
| RAW |
| GND | |
Buzzer | + | 10 |
- | GND | |
Keypad | 5V (red) | VCC |
GND (black) | GND | |
Signal (yellow) | A0 |
Get the keypad with it's wires, two screws, two nuts and two washers.
Two screws are enough to fit the keypad, but if you are a more solid builder than me and don't like things halfways, put four.
Place the breadboard onto the specially designed place for that.
This is how it should be. If you have followed our keypad, schematics, the wires go like this:
Red - Vcc
Black - GND
Yellow - A0
We had to change actor due to very important reasons that we can't explain right now.
You have finished your Escornabot, you now have to upload the code to the Arduino (this is how to configure it), connect the batterys (red to RAW and black to GND) and… start playing!
