Hello!
I have done a little wifi robot with a Raspberry Pi and other components.
Let me present it!
Ps: be indulgent, itβs my first instructable!
Step 1: Things Youβll Need
You will need:
β a Raspberry Pi (35 Eur)
β raspberry cam (17,50 Eur)
β wifi key (use a compatible one) (3,70 Eur)
β a DC-DC Converter Step Up Boost Module 2-5V to 5V 1200mA (1,81 Eur)
β a XL6009 DC-DC Adjustable Step-up boost Power Converter Module (1,58 Eur)
β a L298N DC Stepper Motor Drive Controller Board Module Dual H Bridge (2,23 Eur)
β two Mini USB 5V 1A Lithium Battery Charging Board (5 for 3,73 Eur)
β two 18650 battery holder (2x1Eur)
β two 18650 battery (donβt buy them on ebay! Use Samsung ones) (2 for 10,50 Eur on Amazon: QUMOX)
β two switch (10 for 2,71 Eur)
β the tamiya double gearbox 70168 (12,18 Eur)
β the tamiya tracked chassis kit 70108 (16,74 Eur)
β a 40Pin connector Single Row Straight Female (10 for 4,99 Eur) and use less than one
β a rectifier diode (to protect the raspberry) (100 for 1,07 Eur)
β breadboard (used a very little bit)
β M3 10mm Spacers (25 for 1,83 Eur)
β some wire
β a screwdriver
β a cutter
β a multimeter
β a solder
β a drill
β 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)
Step 2: Build the platform
In this step you need:
β a screwdriver
β a cutter
β the tamyia double gearbox
β 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!
Step 3: Power supply for the Raspberry Pi
Here we will assemble the power supply for the Raspberry.
In this step you need:
β a DC-DC Converter Step Up Boost Module 2-5V to 5V 1200mA
β a Mini USB 5V 1A Lithium Battery Charging Board
β a 18650 battery holder
β a 18650 battery (donβt buy them on ebay! The one on the photo is very bad quality!)
β some wire
β a switch
β a solder
How to proceed:
Just solder the different parts like the schema. After you can add the battery and test it.
Step 4: Power and drive the motors
In this part we will connect all the parts to drive the two DC motor of the gearbox
In this step you need:
β a XL6009 DC-DC Adjustable Step-up boost Power Converter Module
β a Mini USB 5V 1A Lithium Battery Charging Board
β a L298N DC Stepper Motor Drive Controller Board Module Dual H Bridge
β a 18650 battery holder
β a 18650 battery (donβt buy them on ebay! )
β some wire
β a switch
β a solder
β the tamyia double gearbox
β a screwdriver
β 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.
