Arduino User Controlled Fighting Robot

Hi, my name is Piyush and this is my Human Fighting Robot which is controlled by the user by the remote. This is an intermediate project on a difficult scale but the result is so worth making. This is a clear step-by-step instruction on how to make it yourself. this post contains videos to make it easy to understand and build the robot.

GOOD LUCK!

Supplies

-6 tactile push buttons

-male-to-male and male-to-female jumper wires

-2 arduino unos

-Arduino cable and computer to program it

-2 HC-05 Bluetooth modules

-1 breadboard

-14 MG995 servo motors

-MANY screws and bolts for servo motors

-metal parts for servo is from Skyfi Labs company (not custom made)

-2-4 metal strips

-servo bearings

-3 servo horns

-power cable to cut for the servo driver

-plug for power cable

-2A12 16 channel servo/PWM driver

-double sided tape

Here are some pictures of some:

Step 1: Connections for HC-05 and Code

Connections for both Arduino's:

RX pin - pin 13 of Arduino UNO

TX pin - pin 12 of Arduino UNO

GND pin - GND (Ground) of Arduino UNO

VCC pin - 5V pin or VIN pin of Arduino UNO

After the connections, upload this code ↓↓↓ and then unplug the usb connected to the Arduino. Next, hold the button on the HC-05 and replug the Arduino, and once the HC-05 starts to blink slowly, you can release your hand, this process will put the HC-05 in AT mode. Next, open the serial monitor which is the magnifying 🔍 icon on the top right corner of Arduino IDE.

Step 2: BT Module(HC-05) With Slave and Master Configuration

Follow the pictures with there commands, the command is written on top and the response is on the bottom shown as the output in the serial monitor.

important ! : make sure that you have the same settings as me.

AT COMMANDS:

AT- to see if the the Hc-05 is in AT mode and you should receive "OK", which means it is good to set up.

AT+UART=38400,0,0 - set the baud rate to communicate both the BT modules properly so they understand what they send to each other.

AT+ADDR?-copy the address of the BT module because to link them , you need to store their address in each other's BT module. So copy the address or write it on paper

AT+CMODE=0- this command makes the BT module to only focus on 1 more BT module

AT+ROLE=0/1-set the role to either 0 or 1 which makes the BT module either slave or master

Step 3: Setting All Servo Motors to 90 Degrees

Take 3 male-to-male jumper wires and fix them to your Arduino

Red wire of servo (VCC) to Arduino VCC

The brown or black wire of the servo (GND) to Arduino GND

Yellow or orange wire of servo (DATA) to Arduino pin 2 (Temporary only for this step)

Next, upload this code then keep on switching the servos to set them all to 90 degrees:

Step 4: Build the Controller

first, take the six push buttons and place them on the breadboard in a way so all of the first side of the switch is connected to the ground pin and the other pin to its own digital read pin on the Arduino UNO (Remember that your controller does not have to look exactly the same as mine)

switches | pin

1 | 2

2 | 3

3 | 4

4 | 5

5 | 6

6 | 7

The Bluetooth module should already be connected to the Arduino UNO. After everything is done, upload this code for the controller:

Step 5: Building the Robot

Materials (this is the list of items you need, get some extra things in case you need them):

2 hands:

14 servo bracket

14 servo bracket mount

14 metal horns(gear for servo roter)

6 mini screws

104 screws

106 bolts

10 bearings

2 metal strips for hip

2 big U bracket 

10 pcs 90-degree angle 

14 servo motors

here's how to make it:

Step 6: IMPORTANT

There have to be things kept in mind like the position of the servo motor. when fixing the place of the servo, make sure that the servo is set at the correct angle.

Step 7: Poses

To customize the code, watch this video: https://youtu.be/dz8IpfZ0b90

Step 8: You Should Be All Done!

Plug in the robot and the controller to a power source or you can attach batteries to the Arduino UNO like this,

watch the 2 Hc-05 connect. Then use the controller to control the robot and see it do YOUR custom moves!

Step 9: Demonstration

This is the Demonstration of my robot to see how it should work.

Thank you for joining me on the process of Building this Robot and hope you learned something
