The desired output expected from making this instructables was to
make a low cost quad copter from easily available materials. I spent only 3$ for the completion of this project. But I couldn’t accomplish the main characteristics of any drone, that is it won’t fly due to inefficiency of motor (I used dc toy motors). Note that It is not a working model and I have not included any control circuit .The main aim was to make a cheap quad copter .The design of frame and propeller for this project is explained in the description.
Step 1: Materials Used:
1. Plastic ball(2 cm radius)
3. Dc toy motor-4
4. Aluminum can (from spray bottles)
5. Used pen(It used to insert the propeller into motor)
6. Glue gun
8. A battery eliminator to vary the power supply
Step 2: Design of Frame:
The arms of quad copter are made as per the following dimension.
The Styrofoam piece is cut as per the dimension given
By using glue gun fix the prepared arms to the plastic ball
Step 3: Fixing Motors:
Fix dc motors to the edges of quad copter arms as per the image
Step 4: Connection Diagram:
Connect it as per the following image
Note that opposite arm should rotate in same direction .For example
here in my case 2 and 4 motor rotate in counter clock wise direction and 1 and 3 motor rotates in clock wise direction to balance the weight.
Step 5: Design of Propeller:
As main objective is to make a cheap quad copter, I made propeller
also from scratch, note that the design is not effective .
I have used aluminium can, Styrofoam pieces and a pen to build a
Keep aluminium can in between 2 Styrofoam piece and stick it with
glue gun .fix cut piece of pin to the down part using glue gun.so you can insert it into motor easily.my proto type model is given below.
Step 6: Final Assembly:
