RaspiRover

Hello!

I have done a little wifi robot with a Raspberry Pi and other components.

Let me present it!

Ps: be indulgent, it's my first instructable!

You will need:

- a Raspberry Pi (35 Eur)
- raspberry cam (17,50 Eur)
- wifi key (use a compatible one) (3,70 Eur)
- a DC-DC Converter Step Up Boost Module 2-5V to 5V 1200mA (1,81 Eur)
- a XL6009 DC-DC Adjustable Step-up boost Power Converter Module (1,58 Eur)
- a L298N DC Stepper Motor Drive Controller Board Module Dual H Bridge (2,23 Eur)
- two Mini USB 5V 1A Lithium Battery Charging Board (5 for 3,73 Eur)
- two 18650 battery holder (2x1Eur)
- two 18650 battery (don't buy them on ebay! Use Samsung ones) (2 for 10,50 Eur on Amazon: QUMOX)
- two switch (10 for 2,71 Eur)
- the tamiya double gearbox 70168 (12,18 Eur)
- the tamiya tracked chassis kit 70108 (16,74 Eur)
- a 40Pin connector Single Row Straight Female (10 for 4,99 Eur) and use less than one
- a rectifier diode (to protect the raspberry) (100 for 1,07 Eur)
- breadboard (used a very little bit)
- M3 10mm Spacers (25 for 1,83 Eur)
- some wire

- a screwdriver
- a cutter
- a multimeter
- a solder
- a drill
- a glue pen

All the components are bought form Ebay, also the battery and the raspberry pi came from Amazon.

The total price of this instructable is about 108 Eur (134 USD) (Raspberry Pi, camera, and battery included)

In this step you need:
- a screwdriver
- a cutter
- the tamyia double gearbox
- the tamyia tracked chassis kit

How to proceed:

You have to build the tracked platform, first you should build the double gearbox and after assemble the chassis kit with the double gearbox (not the one in the chassis kit)

It is very simple, you have just to follow the manual!

Here we will assemble the power supply for the Raspberry.

In this step you need:

- a DC-DC Converter Step Up Boost Module 2-5V to 5V 1200mA
- a Mini USB 5V 1A Lithium Battery Charging Board
- a 18650 battery holder
- a 18650 battery (don't buy them on ebay! The one on the photo is very bad quality!)
- some wire
- a switch
- a solder

How to proceed:

Just solder the different parts like the schema. After you can add the battery and test it.

In this part we will connect all the parts to drive the two DC motor of the gearbox

In this step you need:

- a XL6009 DC-DC Adjustable Step-up boost Power Converter Module
- a Mini USB 5V 1A Lithium Battery Charging Board
- a L298N DC Stepper Motor Drive Controller Board Module Dual H Bridge
- a 18650 battery holder
- a 18650 battery (don't buy them on ebay! )
- some wire
- a switch
- a solder
- the tamyia double gearbox
- a screwdriver
- a multimeter

How to proceed:

Just solder the different parts like the schema. After you can add the battery and with the multimeter and the screwdriver, adjust the voltage at the out of the Step-up Power Converter to 5v.

In this part we will build the connector between the raspberry and the motor-driver.

In this step you need:

- a 40Pin connector Single Row Straight Female
- a rectifier diode (to protect the raspberry)
- breadboard
- some wire
- a solder

How to proceed:

Just solder the different parts like the schema.

In this part we will mount on the platform the different parts

In this step you need:

- all the parts prepared before
- M3 10mm Spacers
- a drill
-a glue pen

How to proceed:

With a drill, make two holes and put in each a spacer.

Fix the Motor Drive Controller, XL6009 Power Converter, and the raspberry. Then you can connect the raspberry to the Motor Drive Controller.

Use the glue pen to fix the switches and the Battery Charging Board.

In this step you need:

- all the parts prepared before
- raspberry cam
- wifi key (use a compatible one)

How to proceed:

1. Install the wifi key on the raspberry (a lot of tutorial on the Internet)

2. Install raspivid and nc (or verify if it is already installed) on the raspberry

3. Download MPlayer and netcat on your computer.

4. Launch on the computer the folowing command:

nc64.exe -L -p 8554 | mplayer.exe -vo direct3d -fps 31 -cache 1024 -

5. Launch on the raspberry the flowing command:

raspivid -w 1280 -h 720 -fps 25 -t 0 -o - | nc (computer ip) 8554

In this step you need:

- all the parts prepared before
- raspberry cam
- wifi key (use a compatible one)

How to proceed:

1. Install Python on the raspberry

2. Download and lauch the python file.

Use the arrow of the computer to command.

In this step you need:

- All the parts prepared before
- Foam paper
- Glue
- Cutter
- Rule
- A pen and a rubber

How to proceed:

1. Mark all the pieces on the foam paper

2. Cut the pieces

3. Make the hole for the camera

4. Glue the pieces

5. Cut the holes for the axis of the wheel

A little advice, you should add some holes on the top because it can run hot when you use it.
