SmartPhone Control Mini Panther Tank 3D Printed

I am going to show you how to make a mini Panther Tank. This Tank can be controlled by any smartphone from anywhere via internet.The controlling App is made with Blynk & it's free to use. The Tank is fully printable with 3D printer and for ease separate section are made which can be printed easily. This Panther Tank also has led Light in front which can be controlled by smartphone & also its movement & speed. Panther Tank battery can also be charged via any smartphone charger.

1. Double Sided PCB Board
2. D1 Mini
3. TB6612FNG Motor Driver
4. 134N3P Charger Module
5. N20 Motor x 2
6. 3.7 Lipo Battery
7. GT2 Belt 6mm/9mm
8. 3mm Led x 2
9. Switch

Mini Panther Tank is designed with Tinkercad. This can be fully Printable with 3D printer. For Easy Printing the Tank is divided into small parts which can assembled easily. The main 2 Parts Top & Bottom need to glued together.And also i have made 2 set of wheels one is for 6mm GT2 Belt another for 9mm GT2 belt. So print the wheel set according to belt size. 6mm belt is easily available as it widely used for 3D printers. All are made with 0.2mm layer but with different Infill. Check the video described in details infill & also how to remove the supports.

You can download the 3D (.stl) Printable files below.

First you need Double Layer PCB Board & cut it according to inner space of the tank. In one side you put D1 Mini & in opposite side put the Motor Driver.& solder it as per the circuit Diagram. And also trim the legs of the components. Next solder wire for motor output & power connection. Power is coming from Lipo Battery to charging module which is used for charging the battery and output from this module is 5 volt which drives the component & motors of the Tank. Check the video for details instruction.Also 2 Leds are connected parallel to D6 Pin(+) & negative to common ground. Also you need to remove the usb port from charging module & solder wire for getting power 5 volt.

I have made 2 set of wheels one is for 6mm GT2 Belt another for 9mm GT2 belt. So print the wheel set according to belt size.Next Cut the belt on middle of the teeth & the belt should't be tight. It should easily fit. After cutting use Feviquick adhesive to fix it & done your belt is ready. Note that 6mm belt is easier to cut then 9mm belt.

First insert the PCB Board with components D1 Mini should be facing Top. Then Connect the motor in the back & close the cover . There are no screw you need to put a straw or a 3D Printer filament in the hole & trim the edge so that it doesn't obstruct with wheels. Next insert the charging module with the the 3D printed board it will fit perfectly . Insert the Lipo Battery to the top section & connect it with Charger module.Then connect the 5 volt positive wire(output) from charging module to switch & to power the PCB board.Also connect the Led parallel to D6 Pin(+) & negative to common ground.Next Glue the Tank Top & bottom section together. And Finally insert the Front Module with switch & Led. Next insert the two geared wheels then belt . Finally put the free wheels & the wheel cap with little glue. Place the turret at top of tank done... Check the Video for details instruction.

Now download the code below & open Arduino IDE select board D1 mini & upload the code to D1 Mini. Next download & install Blynk to your phone. Make new project & follow the instruction as per the video.

Now switch on the Tank from front panel.Open Blynk & run the newly created project make sure to turn on hotspot or router & control the Tank . Finally enjoy the show check video...
