PANDACORN BOT
Introduction: PANDACORN BOT
Hey Everyone how you doin!
So recently I made this MICRO FIGHTER BOT which was a small Bluetooth-controlled robot that moves really fast.
PANDACORN BOT is a variant of MICRO FIGHTER BOT which has few tweaks like increase length & Height, and a PANDA-UNICORN Hybrid PCB in front which kinda looks like this robot face.
It works exactly the same but the only difference is PCB added at the front part, Pandacorn PCB is another project of mine that I made a few weeks ago.
It's basically a PCB Badge that has LEDs in the Horn Part, LEDs are controlled by a mosfet and this mosfet is controlled by an onboard Attiny13A. In this version, I removed everything from the PCB badge except for the LEDs and Mosfet and use D9 Pin of Arduino Nano to drive the LEDs with a Fade Sketch added into the main code.
In this Instructables, I'm gonna show you guys how I prepared this setup in few easy steps! Let's get started
Supplies
These are the stuff needed for this BOT Project
3D Printed parts-
* Base x 1
* Motor Mount x 4
* Front Shield x 1
* Long Pillars x 2
* Long Pillar with pandacorn support x1
* Front and rear rail x2
Components for BOT Base-
* L293D Motor Driver IC
* Arduino NANO
* Custom PCB (which was provided by PCBWAY)
* Micro Gear DC Motor
* Female Header Pins
* DC Barrel Jack
* AMS1117
* 4.7uf Cap 1206 Package
* 22uf Cap 1206 Package
* SMD LED 0603 Package
* 1K Resistance 0603 Package
* HC01 Module (SMD Version, not the HC05 module which is for breadboard)
* Battery JST Connector
Components for PANDACORN-
* Custom PCB (which was also provided by PCBWAY)
* LEDs 0603 Blue
* A03400 Mosfet
* 10K Ohms Resistors
Step 1: Basic Structure
So the goal here was to combine two of my recent project to make a new project that is this "PANDACORN BOT" it works the same as before iteration but the only difference is the increase in height&length in the body and the addition of PANDACORN PCB in the front part.
PANDACORN PCB looks like the face of this bot hence the name PANDACORN BOT.
Before actually physically connecting them, I have to redesign a few of its parts.
One of them was the mounting pillar, this mounting pillar part is a cylindrical pillar that connects Main PCB with the Base.
On the front mounting pillar, I added two circles holding pillars that basically hold the pandacorn in its place as pandacorn has two huge holes on it which are like his ears but anyways, I used these holes to fix it on the pillar.
At last, I added two attachments on the front side and backside which I named RIB.
The idea here is to increase the length of this bot to increase its center of gravity.
Oh also, LEDs on PANDACORN PCB Badge are soldered inverted, this is because I have left an opening in the top silkscreen of the PCB, by soldering LEDs in an inverted position, their glowing parts face towards the PCB and we could see their glow through the front side. 982
this is a neat trick which I have adapted from a similar PCB Badge I saw on tindie.
Step 2: 3D Files
following are the files that you need to print.
* Base2 x 1pc
* Front Pillar x 1pc
* Motor mount x 4pc
* Pillar x 2pc
* RIB x2pc
I printed these with PLA at 20% infill.
Step 3: Micro Fighter Bot Short Setup
The whole idea behind making this Micro Robot was to make multiple of these bots and make them fight.
Small Robots each equipped with shields and other kinds of weaponry to attack the opponent microbot. For a detailed version of this Micro Fighter Bot, you can check out its Instructables page but let me explain the working of this robot in simple words.

This Micro BOT is made out of two key things-
* the first is the PCB
* the second is the 3D Printed Base
PCB and 3D Printed Base are held together with 3 Pillars, kinda like in a sandwich configuration. The battery is placed between them and on the bottom side, there are 4 Micro Gear Motors and wheels. 646
