No matter how hard evil tries, it can never prevail over good. This is what Dussehra, a major Indian festival teaches us. To keep the spirit of the festival alive, here’s how you can celebrate it the DIY way – make a DIY archery robot that wards off all kinds of evil letting only the truth triumph!
So, let’s give evil a taste of the power of DIY!

Step 1: Assembly Overview
We are going to divide the making into two parts:
1) Making of the base
2) Making of the bow and arrow mechanism
Step 2: Making of the base
The base of this is the smartphone-controlled robot.
You can find the assembly of the same here.
Now, the blix’s assembly cannot be mounted directly on top of evive, we need a plain base.
Thus, your base is ready.
Step 3: Making the parts of the bow and arrow mechanism
Time to add a bow and arrow mechanism:
We did break it into 3 parts:
- Assemble the Lifting unit of Archery robot.
- The Second part is the platform for the bow.
- Finally, to stabilize the whole mechanism, the third part is added. We even have the place in here, to keep the arrows.
Step 4: Completing the assembly
Fix the one side of the platform to the big gear with the help of parallel connectors.
Stick the 3d printed bow on to the platform with the help of double sided tape and also put the rubber band on the bow.
Step 5: Logic
The metal servo is used to move the bow assembly in the vertical direction and the small servo acts as the trigger servo. With the help of trigger servo, the arrow realizes from the bow.
To pair Dabble with the Bluetooth Module, follow the steps below:
Install the app and open it.
- The four direction buttons are used to control the movement of the robot.
- The top button on the right-hand side(triangle) allows you to elevate the bow assembly by 5° upwards.
- Similarly, the bottom button(cross) is used to lower the bow assembly by 5° with each click.
- The rightmost button(circle) is used to tighten the thread.
- And the button opposite(square) to it is used to tighten the thread attached to the trigger servo which results in losing the arrow.
Step 6: Circuitry of the Robot
- Connect DC Motor to M1 and M2.
- Connect the 2 servo motors to the jumpers on the evive.
- Connect a battery to the evive.
Step 7: Scratch Code:
Step 8: Conclusion
With this, your DIY archery robot is all set to kick down evil! Good luck fighting it!
